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.
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. In 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, less than two percent.
Complete these steps in order to stop this alert in the
Log into RTMT.
Choose Tools > Alert > Alert
Choose Set Alert Properties.
Change the value to 1 or 2%.
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.
