Overview

The system performance and utilization module provides information on system performance and utilization in order to monitor reliability and impact of the electronic medical record system installation.   These indicators include both low level system indicators (CPU load, memory utilization, etc.) as well as application level indicators (# logins per day per user, # of opened charts, etc.). The system indicators are mainly developed using Java Management beans API's statistics. The graphical data is rendered using the Google Charts API.

  1. System Monitoring Indicators

System monitoring is currently focused on gathering and presenting information on low level system indicators on Memory utilization. The v1.0.0 which is the currently available module version provides graphical information on used memory of the OpenMRS installation, based on per second view and per minute views. The per second memory usage table displays data on the used memory for the last two minutes (120s) where the per minute table provides memory usage of the last 30 minutes.

...

The application monitoring is introduced to monitor what usage patterns are occurring number of opened charts during a set time period, number of modified charts during a set time period, number of active log ins etc. This is currently under development and the first phase of the implementation will be available with v 1.1.0 of the module which is due on August 2014.

Google Chrome Extension

 

Fed up of opening the admin panel again and again for the system statistics. Don't worry about it. You can download the google chrome extension for the module from the store. Currently extension is developed for Google Chrome Browser. This will make the module usage simple and quick access to the information.
