Jalasoft.Xian.SmartManagementPacks.F5BigIp.TotalActiveConnections.2.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Total active connections has changed its state.

Knowledge Base article:

Summary

Number of total active connections is under threshold.

Over threshold: The total number of active connections is above the maximum threshold configured in Xian Network Manager 2012.

Under threshold: The total number of active connections is below the minimum threshold configured in Xian Network Manager 2012.

Causes

Over threshold: Increase of network demand.

Under threshold: Network demand below predicted values.

Resolutions

Over threshold: Evaluate nature of connections to ensure they are not remaining active unnecessarily, and reconfigure to fit network requirement, if necessary.

Under threshold: Evaluate device configuration to ensure that it is not excessively limiting the connections, and configure if necessary.
