Alert of specific Pool Fails

GSolari

Hi,

I'm having problems trying to alert over specific pool on two different storages, an Hitachi and a IBM. This is are the errors of the alert test:

For the IBM DS3700:

WARNING        : POOL: LID-STR-BKP:Pool-BKP_00:io_rate : no data at: 15:22:00 23/11/2016 - 600 seconds /home/lpar2rrd/stor2rrd/bin/AlertStor2rrd.pm:953 : 
Util           : POOL: LID-STR-BKP:Pool-BKP_00:io : some problem encountered, continuing with next rule

For the Hitachi:

Working for    : POOL: HUS130_9223267XX:0:resp_t_r : POOL:HUS130_922326XX:0:resp_t_r:5:10:15::Giorgio
WARNING        : POOL: HUS130_922326XX:0:resp_t_r  Pool "0" has not been found in /home/lpar2rrd/stor2rrd/data/HUS130_922326XX/pool.cfg /home/lpar2rrd/stor2rrd/bin/AlertStor2rrd.pm:509 : 
Working for    : POOL-ALL: HUS130_922326XX::io : POOL-ALL:HUS130_92232670::io:7000:10:15::Giorgio

The other configured alerts, for all pools of a storage, works right. Please Your help to solve this issue. Regards Giorgio

DS3K: run below cmd to see if there is any data being updated
 (for pool ID 0, put there another id if pool ID 0 does not exist)
rrdtool fetch data/LID-STR-BKP/POOL/0.rrd AVERAGE -r 300 -s now-900 -e now


HUS: is there pool ID 0?
cat /home/lpar2rrd/stor2rrd/data/HUS130_922326XX/pool.cfg

Thanks for Your Help...

What is local time on your V3700? Is not it couple of minutes back?

regarding HUS issue there is a probolem when pool name is "0". Then it does not work for that. Install this fix:

http://www.stor2rrd.com/download/AlertStor2rrd.pm.gz
Gunzip it and copy to /home/stor2rrd/stor2rrd/bin (755, stor2rrd owner)
-rwxr-xr-x    1 lpar2rrd staff         40985 Nov 24 14:10 bin/AlertStor2rrd.pm
If your web browser gunzips it automatically then just rename it: mv AlertStor2rrd.pm.gz AlertStor2rrd.pm

The local time is the same at the appliance and the V7300, but at the graphs there is no data for the last 10 or 15 minutes.... any idea how to fix this? 

The fix worked great for the HUS, thanks.

regards,

Pavel

I am not sre whay it is 10 - 15 mins back (usually it might be abou 5 - 10 mi back), but it should not be a problem. It can be a problem only for testing from the GUI.

Let it work, set some alert (low limit) and check if you receive an alert.
