Cisco Router: Total IP datagrams Health Monitor

Jalasoft.Xian.SmartManagementPacks.CiscoRouters.TotalIPDatagrams.1.1 (AggregateMonitor)

This monitor catches Xian events that notifies when the Total IP datagrams if has changed its state.

Knowledge Base article:

Summary

Number of total IP datagrams is over threshold.

The total number of processed datagrams is above the maximum threshold configured in Xian Network Manager 2012.

Causes

Sub-optimal configuration that causes slow response, buffering, congestion, and connection timeouts; the router is oversubscribed; there is low CPU availability; or low memory availability.

Resolutions

Perform packet debugging or run a packet analyzer with extreme caution if the CPU utilization is already high. Examine the output of the 'show interfaces switching' command to see which interface is burdened with traffic. Tune the router’s performance to minimize the time a packet remains in the router. If the router is over-used try to distribute the load among other routers or purchase a high-end router. Improve CPU and memory availability to avoid packets that require processor attention to be dropped.

Additional

Monitors the total IP datagams on a Cisco Router.
