Step 2: Check Memory Utilization per Process

Purpose

The standard System Application MIB (RFC 2287, Definitions of System-Level Managed Objects for Applications), describes a set of managed objects that are restricted to information that can be determined from the system itself. The object sysApplElmtRunMemory provides information about applications and associated elements that have run or are currently running on the host system. (See Figure 19.)

Figure 19: System Application MIB Tree

Action

To check memory utilization per process, from a management station that has access to the router, and using a tool such as Snmpwalk, enter the following command:

user-bsd# snmpwalk [common arguments] hostname community object-id

What It Means

The sample output shows the total amount of real system memory, measured in kilobytes, currently allocated to the processes retrieved by the sysApplElmtRunMemory object.

The sysApplElmtRunMemory object shows granular, per-process information about memory usage. For example, the sampled process (3.17.2176) is using 2716 kilobytes of memory.

The sysApplElmtRunName object provides a description of the separate instances displayed in the sysApplElmtRunMemory object. For example, the sampled process is represented by the OID 3.17.2176.
