stor2rrd deletes SVC performance data

Zoltan · September 2016

Hi,

we recently realised that stor2rrd deletes the performance data from SVC. It send this command:

stor2rrd svctask cleardumps -prefix /dumps/iostats 1

Is this a normal operation or some bug? The problem is, if we open a support case at IBM, we need to make a system snapshot and because of this command it will not include the performance data.

Regards,
Zoltan

yes, it runs once a day, when *svcperf* process is restarted (it shoudl happen on the midnight and after upgrade)

But why do you need to delete the dumps? A monitoring software should only read the data and not edit it. Is there a way to disable this?

It has been just implemented, install 2 below files and kill all running svcperf* processes.

http://www.stor2rrd.com/download/SVC.pm.gz
Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)
-rwxr-xr-x 1 lpar2rrd staff 65705 Aug 12 23:46 bin/SVC.pm
If your web browser gunzips it automatically then just rename it: mv SVC.pm.gz SVC.pm

http://www.stor2rrd.com/download/svcperf.pl.gz
Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)
-rwxr-xr-x 1 lpar2rrd staff 26047 Sep 22 07:47 bin/svcperf.pl
If your web browser gunzips it automatically then just rename it: mv svcperf.pl.gz svcperf.pl

Thanks Pavel!
Does this mean, that now the svc performance data will not be deleted on the svc?

Pavel · October 2016

exactly, above version does not delete them

Zoltan · November 2016

Do I need to update these files after I upgarde to newer version (1.35)?

Pavel · November 2016

it is all included in 1.35, just upgrade to the new version.
