Monitor System via SNMP

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

Director Console uses 1.3.6.1.4.1.54322.2 as the base OID to get a list of the exposed OIDs and their corresponding information. You can also use the OID of the individual system components and services in Director Console to retrieve their status.

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

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.

SNMPv2

Syntax for snmpwalk via SNMPv2

snmpwalk -v2c -c <community-string> <api_server_ip> .OID

Here, <community-string> is public by default.

Changing Community String

change-snmpv2-cstring

The community string must be at least eight characters long. Only uppercases, lowercases, and numbers are accepted.

Syntax for enabling SNMPv2

legacy-snmp enable

Syntax for disabling SNMPv2

legacy-snmp disable

SNMPv3

Syntax for snmpwalk via SNMPv3

snmpwalk -v3 -u <user name> -l authPriv -a MD5 -A <user password> -x DES -X <DES key> <api_server_ip> .OID

Here, <DES key> is 5nMpvEenC^pt and <user password> is changeme by default.

Changing Key

change-snmpv3-key

The key must be at least eight characters long. Only uppercases, lowercases, numbers, and symbols except space are accepted.

Changing Password

change-snmpv3-passwd

The password must be at least eight characters long. Only uppercases, lowercases, and numbers are accepted.
