Statistics Monitor Module (smonitor)

Description

The Statistics Monitor tool is an viewer for the statistics provided by OpenSIPS via the Statistics Inteface. The tool is able to display realtime statistic values, but also to sample and to draw charts for the certain statistics (value history).

The statistics monitor module has 3 tabs :

Realtime Statistics Tab
Displays each module that exports statistics . Clicking on the module will show its variables . The posibility to reset the variable exists. When the checkbox is enabled the variable will be drawed in the chart statistics .
Statistics Charts Tab .
Displays a chart (graph) with the evolution of the variable in time. A buttons to clear and refresh the Statistics Charts is present.
Configuration Tab.
- The Sampling Time of the chart - how often the sampling should be done (smaller value means more accurate chart, but more load on your OpenSIPS).
  NOTE: changing this value will delete the history!
- The Chart Size can be configured.
- The Chart History : auto mode - 3 days (default) or it can be manually changed at 1 month interval ( in one-day steps) .

Don't forget to set up the additional tables and the cron script which gathers data from the OpenSIPS servers and inserts them into the DB tables (see INSTALL file).
