Anna,
Yes, that will be it! I was running the wrong command as you surmise.
The GPFSFileSetQuota config appears to be correct:
{
name = "GPFSFilesetQuota"
period = 3600
restrict = "icgpfsq1.cc.ic.ac.uk"
},
However "mmperfmon query gpfs_rq_blk_current" just shows lots of null values, for example:
Row Timestamp gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current gpfs_rq_blk_current
1 2018-10-11-13:07:31 null null null null null null null null
2 2018-10-11-13:07:32 null null null null null null null null
3 2018-10-11-13:07:33 null null null null null null null null
4 2018-10-11-13:07:34 null null null null null null null null
5 2018-10-11-13:07:35 null null null null null null null null
6 2018-10-11-13:07:36 null null null null null null null null
7 2018-10-11-13:07:37 null null null null null null null null
8 2018-10-11-13:07:38 null null null null null null null null
9 2018-10-11-13:07:39 null null null null null null null null
10 2018-10-11-13:07:40 null null null null null null null null
Same with the metric gpfs_rq_file_current.
I'll have a look at the PDF sent by Markus in the meantime.
Thanks
Richard

Hi Richard,
one thing to note.
You tried "mmperfmon query GPFSFilesetQuota" to get metric data. So you used the sensor's name instead of a metric name.
And compared it to "mmperfmon query cpu_user" where you used the metric name.
mmperfmon will not return data, if you use the sensor's name instead of a metric's name. I bet you got something like this returned:
[root at test-51 ~]# mmperfmon query GPFSFilesetQuota
Error: no data available for query
.
mmperfmon: Command failed. Examine previous error messages to determine cause.
The log entries you found just tell you, that the collector does not know any metric named "GPFSFilesetQuota".
Please try the query again with gpfs_rq_blk_current or gpfs_rq_file_current.
If the collector never got any data for that metrics, it also does not know those metrics' names.
But since you do not see any data in the GUI this might be the case. In this case please check with "mmperfmon config show"
if the restrict field is set correctly. You should use the long gpfs name and not the hostname. You can check, if the configuration file was distributed
correctly in checking the /opt/IBM/zimon/ZIMonSensors.cfg on the node that is supposed to start this monitor. If the mmperfmon command was
able to identify the restrict value correctly, this node should have your configured period value instead of 0 in ZIMonSensors.cfg under the GPFSFilesetQuota sensor. All other nodes
should include a period equal to 0.
Furthermore, of course, the period for GPFSFilesetQuota should be higher than 0. Recommended is a value of 3600 (once per hour) since the underlying command
is heavier on the system than other sensors. Change the values with the "mmperfmon config update" command, so that it is distributed in the system.
E.g. "mmperfmon config update GPFSFilesetQuota.restrict=<long_gpfs_name>" and "mmperfmon config update GPFSFilesetQuota.period=3600"

Hi all,
Maybe I'm barking up the wrong tree but I'm debugging why I don't get a nice graph in the GUI for fileset capacity, even though the GUI does know about things such as capacity and inodes and usage.
So off I go to the CLI to run "mmperfmon query GPFSFilesetQuota" and I get this:
Oct-10 16:33:28 [Info ] QueryEngine: (fd=64) query from 127.0.0.1: get metrics GPFSFilesetQuota from node=icgpfsq1 last 10 bucket_size 1
Oct-10 16:33:28 [Info ] QueryParser: metric: GPFSFilesetQuota
Oct-10 16:33:28 [Warning] QueryEngine: searchForMetric: could not find metaKey for given metric GPFSFilesetQuota, returning.
Oct-10 16:33:28 [Info ] QueryEngine: [fd=64] no data available for query
Is this a golden ticket to my problem or should I be checking elsewhere?
I'm following a troubleshooting guide here:
https://www.ibm.com/support/knowledgecenter/en/STXKQY_5.0.1/com.ibm.spectrum.scale.v5r01.doc/bl1pdg_guiperfmonissues.htm
and from the page directly within the GUI server itself.
Notably, other things work ok:
[root at icgpfsq1 richard]# mmperfmon query cpu_user
Legend:
1: icgpfsq1|CPU|cpu_user
Row Timestamp cpu_user
1 2018-10-10-16:41:09 0.00
2 2018-10-10-16:41:10 0.25
3 2018-10-10-16:41:11 0.50
4 2018-10-10-16:41:12 0.50
5 2018-10-10-16:41:13 0.50
6 2018-10-10-16:41:14 0.25
7 2018-10-10-16:41:15 1.25
8 2018-10-10-16:41:16 2.51
9 2018-10-10-16:41:17 0.25
10 2018-10-10-16:41:18 0.25
I'm running 5.0.1-2 on all nodes except the NSD servers which still run 5.0.0.2.
Thanks
