To query any SNMP attribute, the following details are needed:
IP Address of Administration Console
Community string name
Object Identifier (OID) of the attributeID
IP address of the device - Identity Server or Access Gateway.
For example, you want to query the memory utilization of an Identity Server with IP address 10.0.0.0. The query is issued to Administration Console whose IP address is 192.168.0.0.
You can perform the query either by using the OID or by using the namespace of the object.
The following sections provide the details of the equivalent command to retrieve memory utilization details if you are using the net-snmp package for monitoring:
