RTMT SDL log size become smaller

[samhopealpha]

Hi everybody, 

A month ago, the RTMT still can retrieve the SDL log for the last 30 days
However, in these few days, the RTMT only can retrieve the SDL log for the last 3 hours
Is there anywhere I can check why the SDL log size become smaller?

Thanks in advance

Hi Sam,

You can check under Trace configuration settings under Callmanager serviceability page. There is a setting for the number and size of trace files.

Hi Sam,

You can check the Trace configuration settings as suggested by Manish. In addition to that, you can also check for the call volumes during this time and whether trace setting is detailed because these things will result in traces being overwritten soon.

Are you getting warnings about hitting the watermark for the common partition? Its quite possible your logs are now being flushed out due to that.

Thanks Tristan, Rajan and Manish for the reply

Just check the RTMT Alert Central,

- No alert on LogPartitionLowWaterMarkExceeded.
- Call volumes is high, but that is same as a month ago.

Settings in CUCM > Trace > Configuration
CUCM-Pub / CUCM-Sub > CM Services > Cisco CallManager

Maximum No. of Files : 250
Maximum File Size (MB): 2

Found out something strange in the Remote Browse
there are 251 files,
from SDL002_100_000001.txt.gz .. to SDL002_100_000250.txt.gz (around 300-400 kb)
and one SDL002_100_000404.txt.gz (this one about 1.1MB)

it looks like the trace log does not reach the 2MB

Where should I check for that? or should I restart some service?

Thanks in advance
Sam

If possible restart the callmanager service on one of the servers and see if that helps as ccm service is responsible for these trace files. Please note that this is service impacting and should be done during off production hours.
