clearing VA7100 logs

Peter Oliver_1 — Tue, 25 Nov 2003 07:11:12 GMT

The HP-UX logdel command deletes old logs related to VA7100 disk arrays. However, it doesn't seem to touch the logs in "/var/opt/sanmgr/commandview/server/logs/performance". Does anyone know if it's safe to selectively delete these, or is there another command that you're supposed to use?

Peter,

this is what I found and probably the best way to do it:

You can configure the operating parameters to automatically limit the performance log file size. This is done by adding the following parameters to the PanConfigParams.txt file

PERFORMANCE_DB_MAX_SIZE=nnn
Sets the maximum amount of disk space in Mbytes that performance log files can consume.

Once this limit is reached, the oldest performance log files are automatically deleted. A value of zero will not delete any logs.

PERFORMANCE_KEEP_MIN_LOGS=nn

Regards,
Bernhard

Ooops,

here is the rest...

PERFORMANCE_KEEP_MIN_LOGS=nn

Sets the minimum number of days worth of log files to keep. This parameter overrides the PERFORMANCE_DB_MAX_SIZE parameter if the
two parameters conflict. The default is seven days. For the default case, a minimum of seven days worth of performance log files will be kept for each device regardless of the max disk space setting.

PERFORMANCE_LOG_CLEAN=nn

Defines how often (in hours) the performance logs will be checked to see if log files need to be deleted, based on the PERFORMANCE_DB_MAX_SIZE setting.
The default setting is 24 hours.

Bernhard

That looks like it will do the trick. Where are these settings documented, btw?

Peter,

this is from the CommandView documentation (I would have attached the pdf but it is too large), so look under /opt/sanmgr/doc or similar, alternatively if you have a CD with the (separate) CommandView SW it will be there too.
