Implementing and Administering Avaya Aura® Media Server
Monitoring system performance
About this task
Avaya Aura® Media Server provides performance monitoring tools in Element Manager. The tools provide real-time displays of the key operational measurement counters and gauges.
The performance monitoring tools use HTML5/JavaScript and require you to use Chrome, Firefox, Safari, or Microsoft Edge.
There are seven different views that display over 140 unique operational measurements. You can select the required view using the textual view link on the top left of the page.
The default cluster display mode is nodal. When the clustered mode is selected, the type of cluster is listed and the display adjusts for the cluster type.
Avaya Aura® MS supports two types of clusters:
1+1 High Availability
N+1 Load Sharing
A standalone cluster
is sometimes used to describe an Avaya Aura® Media Server which does not belong to a cluster. 1+1 HA clusters are active/standby, so toggling this mode does not result in aggregation of the measurements.
Operational measurements are grouped by type: Gauges are grouped with other gauges and counters with other counters. Counter displays reset to zero every 15 minutes. Gauges display the current real-time value.
