System Monitoring via SNMP

You can use SNMP to monitor the status of Director Fabric components using OIDs. Director Fabric supports both SNMPv2 and SNMPv3 protocol.

To monitor Director Fabric components, open UDP port 161 and connect to SNMP. For details on how to open a port in the Director setup, go here .

circle-info

Both SNMPv2 and SNMPv3 are enabled by default to localhost. Before exposing the SNMP to UDP port 161, change the default credentials to ensure system security.
