[gpfsug-discuss] Scale / Perfmon / Grafana - services running but no data

Wed Jul 19 08:53:58 BST 2017

I’m having a play with this now too. Has anybody coded a systemd unit to handle step 2b in the knowledge centre article – bridge creation on the gpfs side? It would save me a bit of effort.

I’m also wondering about the CherryPy version. It looks like this has been developed on SLES which has the newer version mentioned as a standard package and yet RHEL with an older version of CherryPy is perhaps more common as it seems to have the best support for features of GPFS, like object and block protocols. Maybe SLES is in favour now?

Cheers,

Greg

Subject: [gpfsug-discuss] Scale / Perfmon / Grafana - services running but no data

Greetings,

I'm currently setting up Grafana to interact with one of our Scale Clusters
and i've followed the knowledge centre link in terms of setup.

https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.3/com.ibm.spectrum.scale.v4r23.doc/bl1adv_setuppmbridgeforgrafana.htm

However while everything appears to be working i'm not seeing any data coming through the reports within the grafana server, even though I can see data in the Scale GUI

The current environment:

From Grafana Server:

[cid:image002.jpg at 01D300B7.CFE73E50]

when I send a set of files to the cluster (3.8GB)  I can see performance metrics within the Scale GUI

[cid:image004.jpg at 01D300B7.CFE73E50]

yet from the Grafana Dashboard im not seeing any data points

[cid:image006.jpg at 01D300B7.CFE73E50]

Can anyone provide some hints as to what might be happening?
