Editions

MyARM is released in Versions as well as in Editions. All editions are based on the same source and therefore carry the same version number. New versions are released as new features and enhancements are available in MyARM. This document refers to version 4.2.6673.0of MyARM.

This brief overview summarizes different Editions and its features:

MyARM Community Edition

Free to use fully compliant ARM 4.0 agent including bindings for C/C++, Java, C# and Python. Manager graphical user interface (UI) and a standalone HTTP-Server providing a modern web user interface (UI). All measured data is stored using SQLite database as backend.

MyARM C/C++ Edition

Provides the ARM 4.0 (ARM 4.1) language binding for the C programming language. A C++ framework which uses the ARM 4.0 C language binding provides an easy to use object-oriented API. Beside the manager GUI and the web UI, command line tools are provided for batch processing of measured data stored in a supported (SQLite or MySQL) database.

MyARM Java Edition

Provides the ARM 4.0 (ARM 4.1) language binding for the Java programming language. For analysing measured data the manager GUI and the web UI and command line tools are provided. Any measured data is stored in a supported (SQLite or MySQL) database.

MyARM C# Edition

Provides the ARM 4.0 (ARM 4.1) language binding for the C# programming language. For analysing measured data the manager GUI and the web UI and command line tools are provided. Any measured data is stored in a supported (SQLite or MySQL) database.

MyARM Standard Edition

Combines the C/C++ and Java Edition by providing the ARM 4.0 (ARM 4.1) language binding for the C/C++ and Java programming languages in a single edition. For analysing measured data the manager GUI, the web UI and command line tools are provided. Any measured data is stored in a supported (SQLite or MySQL) database.

MyARM Enterprise Edition

Combines all three ARM 4.0 (ARM 4.1) language binding editions (C/C++, Java and C#) in one single edition. For analysing measured data the manager GUI, the web UI and command line tools are provided. Any measured data is stored in a supported (SQLite or MySQL) database. For high loads multiple database connections are used to write measured data into the atabase.

Add-ons

The functionality for each MyARM Edition (except MyARM Community Edition) can be extended by so-called Add-ons. An Add-on is a special feature which is additional licensed and enhances the functionality of the MyARM agent. The following Add-ons exists currently:

Real time statistics (RTS)

Real time statistics are used to monitor executed transactions within a production environment to get in overall picture of the performance and health of the whole system including end-to-end response times. For detailed information please read section Real time statistics.

Runtime configuration (RTC)

Transaction runtime configuration is used to manage and control instrumented applications remotely. For detailed information please read section Transaction runtime configuration.

Runtime notification (RTN)

Runtime notifications are used to notify conditions of the running applications by executing a script based on transaction or RTS conditions. For detailed information please read section Runtime notification.

Multiple database connections (MDB)

The MySQL/MariaDB database data sink supports to open multiple connections to a server. For detailed information please read section MySQL database.

FastCGI web applications (FCGI)

The MyARM web applications can be integrated into an existing web server infrastructure which supports the FastCGI protocol. For detailed information please read section FastCGI integration.

History

Here is a short overview of the MyARM development history.
