Controller Based WLANs

What enhancements have been made to the memory monitoring routines in ArubaOS 3.3.x?

Product and Software: This article applies to all Aruba controllers and ArubaOS 3.3.2.24 and later.

Aruba OS 3.3.2.24, 3.3.3.3, 3.4.2.1 and later builds have an enhanced memory monitoring routine. The memory monitor now saves up to 30 logs of debugging information. The logs rotate on a first-in first-out basis so that the most recent log contains the most current debug information. These logs include information on system memory, irregular application memory usage, large files in the ramdisk, large pending tx/rx queues, and memory block usage. This information can be leveraged by Aruba Networks technical support while analyzing nanny post-crash reports.

The memory monitoring logs can be retrieved from the controller by issuing the 'tar logs' or 'tar logs tech-support' commands at the CLI or by downloading the logs from the WebUI.

These logs are stored in the tarred logs under \var\log\oslog\memlogs.
In this folder, you can see a compressed mm_logs.tar.gz file. Unzip the mm_logs.tar.gz file to extract several logs named memlog.01, memlog.02, and memlog.03.

The following sample output of one of these memlog files shows the memory-related information that is collected.
