Source Control Management

Key Features

Source Control Management (SCM) Integration & Tooling

Integration with GIT and Perforce. Conveniently check-in/out, diff history within the AMI web-based dashboard builder.

Multi-file Linker

Dashboards can be comprised of multiple files meaning components can be logically separated for independent management/version control.

Abstraction

Functionality can be marked virtual and overridden in another file, allowing for dashboard designers to abstract out functionality for custom implementation.

Refactoring Tool

Components can safely be renamed and/or moved between files. The tool automatically updates and moves dependencies as necessary with naming conflict resolution.

Dashboard File Stabilization

Changes to a dashboard result in minimum/localized changes to the underlying file. Components can be set to defaults to avoid noisy/unintended changes.

Benefits

Team Collaboration

By logically dividing a dashboard across files, Teams can simultaneously work on sub-components of the dashboard.

Reusable Components

Scripts, datamodels, widgets and entire dashboards can be written once and then reused across dashboards.

Dashboard Tracking, Versioning, Branching

As AMI files are managed by source control, they can be used to label versions of a dashboard, compare versions and manage branching.

Merging Independent Projects

Existing dashboards can be incorporated into new dashboards making it easy to build super-dashboards cross-incorporating functionality

Enterprise Deployment Strategy

Treat AMI files just like any other resources that are managed through deployment strategies, such as uDeploy, TeamCity, etc.

Dashboard Extension

Extend existing dashboards for regional/business line specific usage without needing to maintain multiple near duplicate dashboards.

Full Backwards Compatibility

File

Loads existing dashboards and automatically converts to the new format. Note: files are still json with the same general structure, just less clutter/redundancy.

Usage

Users & dashboard developers can continue to develop/maintain dashboards without change. Changes are purely additive, existing functionality has not been changed nor removed.

Split Dashboards

Split existing dashboards into separate files for better SCM management.

Combine Dashboards

Utilize multiple existing dashboards to create a single super-dashboard.

Key Concepts

Dashboards vs. Layout

Prior to Source Control Management (SCM), a Dashboard was backed by a single Layout file, so the terms were interchangeable. With SCM, a Dashboard can be an amalgamation of multiple Layout files so the distinction matters:

  • Layout: an individual .ami file which contains a set of source definitions such as Panels, Datamodels, Relationships, AmiScript, etc. 
  • Dashboard (Root Layout): the .ami file that is directly opened (ex: File > Absolute File - Open) is considered a Dashboard, or more specifically the Root Layout
Scm.absolutefile.jpg

Included Layouts

A layout file can also include pointers to other .ami Layout FIles (Dashboard > Included Layouts). This forms a Parent Layout/Child Layout Relationship.

Scm.includedlayouts.jpg

Scm.includedlayoutchildparent.jpg

Hidden Panels

A layout file can define panels that are not directly referenced in the dashboard. If a layout includes a child layout, all of the child layout's panels are hidden by default. In order to make a child layout's panel(s) visible, you need to specifically unhide it (Blank Window > Green Button > Unhide Panel). In effect, this is how linking a panel from one layout to another is achieved.

Scm.unhidepanel.jpg

Getting Started

Please ensure this property is set before continuingami.scm.plugins=com.f1.ami.plugins.git.AmiGitScmPlugin

Connecting to Source Control Management (SCM)

Navigate to Account > Source Control Settings, select the appropriate source control type and fill in your user credentials. The base path tells AMI where it expects files to reside which are managed under source control, including sub directories. (files outside that directory will not have source control functionality)

Scm.scmSettings.jpg

Loading/Saving Dashboards in SCM

Traditionally, layouts could only be stored under “my layouts” or “cloud”. Now there is an “Absolute” (File > Absolute File - Open) option which allows you to load/save files anywhere on the host. If you wish to use SCM to manage a layout file, it should be located under the SCM base path (Account > Source Control Settings > Base Path). Tip: To move a layout from my layouts into SCM, simply load it (File > My Layouts - Open) and then save it under said SCM base path (File > Absolute File - Save As).

Link multiple files to a dashboard

Open the project browser (Dashboard > Include Files)

To add an existing file:

Right click on the project > Add Child Link from > Existing File > select the file to add.

To add a new file:

Right click on the project > Add Child Link From > New File > Enter the name of the new, blank file to create.

Notes:

  • The alias defines how objects (panels, datamodels, etc.) within this will be referenced within the main dashboard.
  • Read-only: If selected then, you will not be able to save changes made to the objects within the selected file.
  • Relative Path: If true, then the file will be referenced using a path relative to the parent file; otherwise it will be an absolute path. Relative is preferred for portability.

Link to a panel from another file

Be sure the other file has been included (see Link Multiple files to a dashboard). Create a blank Panel (Window > New Window), click the blank panel’s green button > unhide panel > choose the panel to display

Refactoring

To Move a panel (and it’s dependent objects) from one file to another, click on the panels green button > Move to Different Layout > select the layout to move the panel to.

Using Source Control

  • Open the project Browser (Dashboard > Included Layouts), right click > Add Child Link From > Choose the appropriate action
  • To see most recent changes : File > Diff against last save

Additions to Layout Editor

Hiding Panels

Panel's Green Button > Hide Highlighted Panels

Unhiding Panels

Windows > New Window > Green Button > Unhide Panel > Choose panel to unhide (Note, any blank panel can be used to link to a hidden panel

Tab Per Layout 

Several Resource editor tools are now organized such that there is one editor panel per layout.

  • Custom methods:
    • Dashboard > Custom methods…
  • Custom css
    • Dashboard > Css…
  • Custom callbacks
    • Dashboard > Callbacks…

Owning Layout

All resources now have the concept of an owning layout:

  • Variables: 
    • Adding/editing global variables now allows you to choose an owning layout (Dashboard > Variables Table… > Right Click > Add/Edit/Copy > Owning Layout)
  • Relationships: 
    • Ability to choose which file owns the relationship (Green Button > Add/Edit Relationship > Owning Layout dropdown).
  • Datamodels: 
    • Dashboard > Datamodeler… > Right Click on Datamodel > Config Tab > Owning Layout
  • Panels: 
    • Green Button -> Move To Different Layout File -> Move To Layout

Data Modeler

There is a list of checkboxes on the left to choose which layout’s datamodels/panels to show (Dashboard -> Datamodeler)

Dashboard Objects

View for seeing all relationships (Dashboard > Dashboard Objects). Note: This was added to allow access to hidden relationships, which is a new concept. A relationship is hidden if its source or target panel’s are hidden.

Advanced Concepts

LAYOUT FILE

Previously an .ami json file was considered a fully-contained dashboard. Now, an .ami file should be thought of as a collection of resources such as panels, datamodels, code, etc. and can contain references to other .ami files. An individual .ami file is referred to as a layout. There are a few key points:

Root Layout

This is the file that was directly loaded (ex: File > Absolute File - Open) and is used as the “bootstrap” to determine which windows are loaded and displayed within the desktop.

Parent/Child Layout Relationship

A layout can include any number of child layouts such that each included layout must have a uniquely identifying alias. Note that the root Layout has no parent

Layout Alias

Each layout (.ami file) within the dashboard is uniquely identified using an alias (note that when you attach a child layout, you are prompted to choose a unique alias). This alias is used to reference objects within the layout.

Layout Nesting

Because layouts can recursively include other layouts, it’s possible to have child layouts, grandchild layouts, etc. In this case the alias is constructed by dotconcatenation, ex: a.b.c

Complex Nesting

Circular references are not supported (ex; A.ami -> B.ami -> A.ami). Diamond references are supported (A.ami -> B.ami -> C.ami & A.ami -> D.ami -> C.ami).

Read-only/Locked

A layout file can be marked as read-only (Dashboard > Included Layouts > (right click) > Permissions). If the same file is referenced multiple times (as with the diamond pattern) then only one instance will be editable, and the others will be locked.

ALIAS-DOT-NAME (ADN)

Previously, all panels where identified by a unique panel ID. Now, uniqueness is enforced by combining a panel’s owning layout’s fully qualified alias plus the Panel Id. Same goes for uniquely identifying datamodels and relationships.

SCOPING

Parent layouts have access to the resources of child layouts but child layouts do not have visibility to parent objects. This is an important concept that enforces clean modularization.

CUSTOM AMISCRIPT METHODS & VARIABLE SCOPING

Because a dashboard can incorporate multiple layout files, it’s possible for the same method definition to exist in duplicate. Depending on where the AmiScript is getting executed, the appropriate version of the method will be run. For example, a parent layout could import two child layouts, each with their own onButton() method. Datamodels (or other resources) in child1 calling onButton() will get child1’s method and Datamodels in child2 calling onButton() will get child2’s version of the method. A subtle detail, if the parent layout did not define its own onButton() method and were to call onButton(), it will get the child with the higher priorities version… (See Dashboard > Included Layouts > (right click) > Move Up Higher Priority/Move Down Lower Priority)

AMISCRIPT LAYOUT OBJECT

A new, important Layout class has been introduced, which is used to represent each layout file loaded within the dashboard. The layout variable is automatically visible within AmiScript (like the session variable) and is associated with the layout that the AmiScript is owned by. This is important because it maintains relative consistency when referencing other objects with AmiScript. Note, this has replaced several methods from the session class and when loading old layouts AMI will automatically convert the code to use the layout object instead.

For example, let’s consider a layout B.ami that has two datamodels dm1 and dm2:

B.ami

→dm1

→dm2

Inside dm1, if we want to get access to dm2 we would write:

//I’m inside dm1 Datamodel dm2=layout.getDatamodel(“dm2”);

Say that we have another layout A.ami that includes B.ami with the alias b and has its own datamodel dm0:

A.ami

→dm0

→b

→dm1

→dm2

First, keep in mind the above code will continue to work because its inside dm1 which is owned by layout b so the layout instant represents b. But now, let’s say we want to get dm2 from code inside dm0. We could do either of these:

//I’m inside dm0, all three of these result in same value

Datamodel dm2;

dm2=layout.getChild(“b”).

getDatamodel(“dm2”);

dm2=layout.getDatamodel(“b.dm2”);

dm2=layout.getDatamodel(“b.dm1”).

getLayout().getDatamodel(“dm2”);

The 3rd method is needlessly complex but highlights the relative nature of layouts and resources… We’re grabbing b’s dm1 datamodel. Then because dm1 and dm2 are in the same layout we can simply do getLayout(). getDatamodel(“dm2”) on dm1.

VIRTUAL METHODS

With regards to scoping, it was mentioned that AmiScript within a child layout does not have access to it’s parent’s AmiScript. While generally true, if the layout were to explicitly define a function as virtual and the parent layout were to also define the same method, then the parent’s function will get called instead. In the example below, if we were to call doit() in the child layout, we would see the alerts parent1 and child2 because test1() was marked as virtual, but test2 was not:

Child Layout:

virtual String test1() {
     session.alert(child1);
}
String test2() {
     session.alert(child2);
}
Object doit() {
     test1();
     test2();
}

Root Layout:

String test1() {
     session.alert(parent1);
}
String test2() {
     session.alert(parent2);
}

Connecting to an Excel Datasource

Our goal in this tutorial is to import excel data into AMI and create a visualization. In this example we have an Excel spreadsheet, sine.xlsx, with two columns: Degrees and Sine.

Guides.Excel.01.jpg

1. The first step is to add a new Excel Datasource. In developer mode, click on Dashboard from the menu and open the Data Modeler.

Guides.Excel.02.jpg

Guides.Excel.03.jpg

2. Inside the Data Modeler, click on Attach Datasource. This will bring up the Attach Datasource Window. Select the MS Excel icon from the list of available datasource types.

Guides.Excel.04.jpg

3. In the provided fields, fill out the Name and URL fields. In the Name field, put in the desired name of the new datasource. And in the URL field, provide the full file name (including the path) of the Excel file.

(Warning: prior to adding as a datasource, the Excel file must be closed and saved)

Guides.Excel.05.jpg

4. The successful addition of the MS Excel datasource will be confirmed with a prompt and the appearance of the Excel datasource in the Data Modeler

Guides.Excel.06.jpg

(Note: each sheet in the Excel file will be added as a table to the datasource)

Guides.Excel.07.jpg

5. Double click on the datasource (or right-click and select Add Datamodel to excel) in order to see the tables under the datasource. Select the table and  follow the wizard in order to create a datamodel

Guides.Excel.08.jpg

Guides.Excel.12.jpg

6. Once the datamodel is created, we can create a visualization (please refer to GUI > Creating Your First Visualization). In this example, we will create a line chart. In the wizard, select the appropriate variables for the X and Y axis (i.e, X: Degree, Y: Sine)

Guides.Excel.11.jpg

Guides.Excel.13.jpg

(Hint: on the right side of the wizard, click Refresh to get a preview of the chart or View Data in order to view the data that is being used)

Guides.Excel.16.jpg

7. Click Finish in order to create the line chart based on the data in our Excel sheet

Instructions for Using Python with AMI Script

How to load Python Modules in AMI Script

To import python modules, place the import statements inside the python extern block.

By default AMI looks for Python Libraries in the lib/Lib directory of amione.

Alternatively, you can also set the JYTHONPATH environmental variable and AMI will load libraries from there.

{
 CREATE TABLE _TABLE AS USE EXECUTE SELECT TableName, Broadcast, RefreshPeriodMs, SourceTableNames, PersistEngine, OnUndefColumn, DefinedBy FROM __TABLE WHERE ${WHERE};

  double n = 0;
  extern python {{
    import math
    n = math.pow(2,3)
  }};
  session.log(n);
}

How to use Python in AMI Script

Below is an example of how you can pass in variables and tables and modify and return them:

{
 CREATE TABLE inTable AS USE ds=AMI EXECUTE SELECT * FROM __TABLE;
 //INPUT VARIABLES
 String findEngine="TEXT";
 Table inTable=select * from inTable;
 //OUTPUT VARIABLES
 int foundCount;
 Table outTable=new Table("out","Name String");
 //Loop through each row of inTable and add TableName to outTable for records that have a PersistEngine equal to findEngine Variable
 //foundCount is incremented for each record added to outTable
 extern python{{
   foundCount = 0
   for row in inTable.getRows():
     if(row.get("PersistEngine") == "TEXT"):
       outTable.getRows().add(outTable.newRow(row.get("TableName")))
       foundCount+=1
 }};
 create table outTable=outTable;
 session.log("found: "+foundCount);
}

Using JDBC adapter to connect to AMIDB

Sample JDBC connection to AMI Center

import java.sql.*;
public class AmiJdbcSample {
//IMPORTANT NOTE: be sure to include out.jar in your java classpath. The out.jar file is located in the lib folder of your ami installation
    public static final String NEW_LINE = System.getProperty("line.separator");
    public static void main(String a[]) throws SQLException, ClassNotFoundException {
        Class.forName("com.f1.ami.amidb.jdbc.AmiDbJdbcDriver");
        final String url = "jdbc:amisql:localhost:3280?username=demo&password=demo123";
        final Connection conn = DriverManager.getConnection(url);
        try {
            final ResultSet rs = conn. createStatement().executeQuery("select * from __TABLE");
            System.out.println(resultSetToString(rs));
        } finally {
            conn.close();
        }
    }
    public static String resultSetToString(ResultSet rs) throws SQLException {
        final StringBuilder r = new StringBuilder();
        final ResultSetMetaData metaData = rs.getMetaData();
        final int columnCount = metaData.getColumnCount();
        for (int i = 1; i <= columnCount; i++)
            r.append(metaData.getColumnName(i)).append(i == columnCount ? NEW_LINE : "\t");
        while (rs.next())
            for (int i = 1; i <= columnCount; i++)
                r.append(rs.getObject(i)).append(i == columnCount ? NEW_LINE : "\t");
        return r.toString();
    }
}

Using JayDeBeApi - Python JDBC Adapter for AMI

Prerequisites: A jre (Java runtime environment, for JDBC) needs to be installed.

1. Install the JayDeBeApi module.

JayDeBeApi is an adapter of JDBC for python. You can install it using pip:

pip install JayDeBeApi

Alternative ways to install JayDeBeApi: https://pypi.org/project/JayDeBeApi/

2. Start AMI One

3. Connect to amisql from python:

a. You’ll need the path to the out.jar file. This can be found in the ami/amione/lib folder.

b. Find the server hostname and ami.db.jdbc.port (default is 3280).

c. Copy this script, replacing the <placeholders> with appropriate values:

import jaydebeapi

conn =

jaydebeapi.connect( "com.f1.ami.amidb.jdbc.AmiDbJdbcDriver",

"jdbc:amisql:<hostname>:<port>", {"user": "<username>",

"password": "<password>"}, "<path/to/out.jar>")

4. To run queries, create a cursor:

curs = conn.cursor()

5. Queries can then be executed using the execute method:

curs.execute ("show tables")

6. Results are fetched using the fetchall method, which returns a list:

print(curs.fetchall())

7. Close the cursor once finished:

curs.close()

You can also execute queries within a with block for the cursor so you don’t have to worry about closing it:

with conn.cursor() as curs:

curs.execute("show tables")

result = curs.fetchall()

Super Filter Layout

1. overview
The Super Filter layout provides a simple method for filtering common column values across multiple tables.

2.Setup
(1). In the layout which you want to use the super filter layout, include the SuperFilter.layout file through the Included Layouts panel.
(2). Open the SuperFilter.layout file, and use the SuperFilter window to pass in a mapping json (see JSON reference) and its corresponding mapping id.
(3). Open your layout and attach a new data model with the following script:

 spr_fltr_initTable("PANELNAME", "MAPPINGID", null);

Where PANELNAME is the name of the panel containing the super filter and MAPPINGID is the earlier created id. (4). Create a new panel in your layout with the name PANELNAME, and attach a table visualization on top of the previously created data model. If everything has been setup correctly, you should see a table `SEARCH FIELDS` containing your column names.
(5). Finish creating the panel and open the AMISCRIPT callbacks, on the onFilterChanging() tab, add the following line:

spr_fltr_tableFilterSearch(this,null);

(6). Submit your changes and the filters on the super filter should affect the target tables.

3. JSON Config

     "DmMapping": {
        //Table name should correspond to the data model name
        "TABLE_A": {

Managing 3forge AMI for Multiple Environments

Introduction

3forge AMI refines the software development life cycle and improves on developers ability to write high impact code. It allows you to make rapid changes and see iterative improvements which need to be maintained overtime. This document provides a general template to manage and ensure that the development of dashboards is properly maintained for multiple environments.

The following components of 3forge AMI will need to be managed: AMI Layouts, the AMI DB Schemas, AMI Config Properties, AMI Datasources, Aeskey, Scripts, AMI Libraries. There are also additional sections in this document which may be useful such as Source Control, and AMI Database persist data files.

Environments

We recommend that development teams create multiple environments as necessary when working with AMI. Here's a recommendation, modify as necessary.

DEV - This environment is for day to day rapid changes.

QA - This environment is for promoting DEV changes for testing.

UAT - This environment should be set up with testing data but production volumes, it is for pre-production testing.

PROD - This is your production environment.

For each environment you should configure a custom properties file.

Note: You may want to set up a failover production environment to provide a backup server if a production change is not performing as expected.

Alternative Folder Structure

Note: You may to set up the environment folders at the top level, in this document we set up the environment folders at section to show developers how to manage important files.

At the root level make as many environment folders as you need.

Inside each environment folder, you should create the following subfolders that need to be managed and any additional ones you need. The below is an example.

Layouts

One of the key files you need to maintain are the dashboard layouts. These layouts are json files that define how a layout is constructed in the 3forge AMI frontend.

For the purposes of managing multiple environments we will only be using the cloud layouts.

There are three main ways 3forge AMI supports saving files: a local user file, an absolute file, and as a file in your local cloud directory. Local files are where 3forge AMI developers can make and test changes that are only visible to them. Absolute layouts can be saved anywhere on the server's file system. Cloud layouts are shared layouts available to users who have access to them.

How to Manage Layout Files for Multiple Environments

By default cloud layouts are stored in your data/cloud directory. We recommend making a cloud directory for each environment and configuring your AMI instance to use the cloud directory for that environment.

Example: Cloud directory structure

Properties

ami.cloud.dir=path/to/cloud

AMI Database Schemas

The AMI Database (AMIDB) is a core component of 3forge AMI, it allows you store and cache data for aggregations and analytics. The files that define the schema of AMIDB are amisql files.

There are two types of schema files, one is managed by 3forge AMI which allows the addition of new tables, procedures, triggers, and timers while AMI is running. The other schema files are preconfigured and any tables, procedures, triggers and timers defined in these files cannot be modified.

By default 3forge AMI only starts with the managed schema file located in

data/managed_schema.amisql

Schema Structure

We recommend creating a folder structure like below for managing your schema files across deployments. You should place your managed schemas and config schemas in these folders.

Multiple Environments.04.jpg

Properties

ami.db.schema.config.files=path/to/configSchema.amisql,path/to/configSchema2... ami.db.managed.file=path/to/managed_schema.amisql

Note: When defining config files, use a comma delimited format without spaces.

Configuration Properties

Configuration properties are located in your config directory. Each install contains the following default property files, these files should NOT be modified:

root.properties - contains the default included property files

defaults.properties - contains the default properties

speedlogger.properties - contains the default logging properties

By default 3forge AMI developers should create a local.properties file and place custom properties in it. To configure properties for each environment, they can make separate property files for each environment.

To use those property files they can use the #INCLUDE directive to include that property file.

Example: Properties Files

Multiple Environments.05.jpg

Note: Using folders is a good way to organize properties by environment

Multiple Environments.06.jpg

Properties

#INCLUDE path/to/env.properties

Datasources.dat and amikey.aes

The __DATASOURCE.dat file contains datasource connection properties that 3forge AMI is connected to. Datasource connection details may differ in each environment. That is why datasources are accessed through its name and are pointers to the datasource configuration which contains details such as datasource connection url.

Example __DATASOURCE.dat file

For example, if the dashboard is connected to a Mysql and a Kdb database, the file will contain two entries containing the connection details.

To make sure 3forge AMI connects to the intended datasources depending on the environment we recommend creating a folder for each environment and place the __DATASOURCE.dat file in them. Lastly we need to edit the environment specific property file to indicate the location of it.

Based on the screenshot below, the property for the dev environment would be:

# //Inside dev.properties
ami.db.persist.dir.system.table.__DATASOURCE=persist/dev

For prod it would be:

# //Inside prod.properties
ami.db.persist.dir.system.table.__DATASOURCE=persist/prod

Amikey.aes

It is very important you manage your amikey.aes properly. This key is used for encrypting the connection details for your 3forge AMI datasources. It is recommended you have different amikey.aes keys for each environment. By default the key is located in your persist directory.

This key can be configured through the property:

ami.aes.key.file=path/to/amikey.aes

Multiple Environments.08.jpg

Properties

ami.db.persist.dir.system.table.__DATASOURCE=path/to/datasourcesfolder ami.aes.key.file=path/to/amikey.aes

Scripts

The scripts folder contains the startup scripts for 3forge AMI. We recommend managing your start script in source control if you change or customize the start script. Some examples of why you may modify the start script: change the amount of memory 3forge AMI reserves and change the Java Garbage collector.

Libraries (Optional)

3forge provides many plugins for connecting to datasources and interfacing with other technologies. By default these libraries get stored in the lib directory. It may be a good practice to enable revision control on the 3forge AMI lib directory especially for production environments if it is necessary to conduct a rollback.

Source Control for Layouts

3forge provides a source control plugin for AMI layouts. This is set up on the AMI server. We recommend each 3forge AMI Developer to create a separate branch with the developer's userid as the branch name. They should pull from the main branch and merge into the main branch when submitting change

Persist Data

3forge stores the AMI Database data files by default in the persist folder. This can be configured through the property: ami.db.persist.dir=path/to/your/persist. You do not want to check this into version control as these files can be very large.

Properties

ami.db.persist.dir=path/to/your/persist

Log Viewer Layout

LogViewerImage.png

Introduction

3forge has a log viewer layout that allows developers to quickly understand resource usage across a single session and can also be extremely helpful with diagnosing performance or memory issues. The layout provides charts detailing the following areas: Messages, Memory, Threads, Events, Objects, Web, Web Balancer, Timers, Triggers, and Procedures.

Please note that this layout does not come pre-packaged with AMI and can be provided separately upon request.

Setup

  1. Load the layout according to how it was saved (Absolute/Cloud)
  2. Load the .amilog file in either of the two ways:
    1. Edit the "AmiLogFile" flat file reader (under Dashboard > Data Modeler...) to point to your log directory, and once done, use the File Name drop down on the main window to select your log file OR
    2. Use the Upload File field on the main window to upload your log file and hit the upload button once selected
  3. Once the log file has been processed, you should see the graphs being populated. Otherwise, please check for any error messages or contact support@3forge.com for further troubleshooting
