Network Device Responsiveness

System.NetworkManagement.Node.IsResponsive (AggregateMonitor)

Aggregate monitor that tracks the overall responsiveness of the network device to both ICMP and SNMP

Knowledge Base article:

Summary

This monitor is the rollup monitor for responsiveness to ICMP or SNMP. If one or more of the subordinate monitors is in a warning state, this monitor will also be in a warning state.

Causes

A warning state for this monitor indicates that the target network device is not responding to either ICMP or SNMP ping messages.

Resolutions

Use the Health Explorer to determine which subordinate monitor is causing the failure. See the knowledge article for the failed monitor for more information on the specific failure.
