Prerequisites

Requirements

Problem

In the Cisco CallManager server, a Swap Partition available disk space below 10 Percent. LowSwapPartitionAvailableDiskSpace partition has 7 percent of available disk space alert appears from the RTMT.

Solution

This alert indicates that the swap partition is left with very less available space, and is heavily used by the system. The swap partition is normally used to extend the physical RAM capacity when needed. Under normal conditions, if RAM is enough, swap should not be used too much.

This alert appears when the default threshold for available disk space is set to a high value. In order to stop the RTMT alert, Cisco recommends to set the default threshold for available disk space to a lower number (for example, <2%).

Complete these steps in order to stop this alert in the RTMT:

1. Log into RTMT.

2. Select Tools/Alert/Alert Central.

3. Right click LowActivePartitionAvailableDiscSpace.

4. Select Set Alert Properties.

5. Click Next.

6. Change the value to 1 or 2%.

7. Click Next/Next.

8. Click Activate.

   Note: As this alert can be caused by a build up of temp files, a reboot of the server is recommanded to clear out any unnecessary temp files.

   Note: Turn off any unnecessary traces configuration. Traces should only be turned on during troubleshooting.
