You can use the SNMPv2 or SNMPv3 to monitor the status of the Director Fabric components and services using their respective OIDs.
Syntax for snmpwalk via SNMPv2:
snmpwalk -v2c -c <community-string> <Server-IP>:161 .OID
Syntax for snmpwalk via SNMPv3:
snmpwalk -v3 -u <user name> -l authPriv -a MD5 -A <user password> -x DES -X <DES key> <Server-IP>:161 .OID
The default values of the parameters used in SNMP monitoring are as follows:
Parameter |
Default Value |
|---|---|
<community-string> |
public |
<user name> |
director |
<user password> |
changeme |
DES key |
