Network Monitoring network devices in pending management

System.NetworkManagement.NetworkDevicesInPendingManagement (UnitMonitor)

This monitor checks whether Network Discovery failed for a number of network devices.

Knowledge Base article:

Summary

Network Devices were unable to be discovered and are in pending management.

Causes

Network Devices in pending management can be caused by an issue with SNMP credentials supplied, intermittent network latency or unexpected blockage of SNMP traffic.

Resolutions

Check to ensure your SNMP credentials supplied during Network Discovery are still valid. Ensure firewall rules are not blocking SNMP access to the devices being monitored. Contact your network administrator for additional troubleshooting.
