In this Section:

The SBC Core uses the OAM Event Log memusage command to log the memory usage of each process over a configurable interval. The SBC generates a memory log which is uses to capture and log process heap memory usage over time.

The following limitations apply in this release: 

  • Memory consumption through interval statistics are not reported.
  • Memory usage is reported at the process level, not for individual threads/tasks.

The number of bytes used by an active process are captured in the memory usage log file:

Processes are identified by the log entries encoded by the system. For example, the format of a log entry:
113 03282017 073341.007995:1.01.00.00006.MAJOR .PRS: memusage: 1516445696

The memory usage details are logged to the hard drive in the directory: /var/log/sonus/sbx/evlog 

Note

Use the log number to locate the correct log file. For example:

/var/log/sonus/sbx/evlog/<log number>.mem

where the <log number>.mem is the memory usage log file.

On the SBC main screen, navigate to All > OAM > Event Log > Memusage.

The Memusage window is displayed.
