Hi Andreas,
hi Neil,

the GUI-Node returned a hostname with a FQDN. The clients have no FQDN.

Thanks for this tip. I will change the hostname in the first step. If this 
does not help then I will change the configuration files.

I will give you feedback in the next week!

Thanks,
Matthias

Hi Matthias,
 
what's "hostname" returning on your nodes?
 
1.) If it is not the one that the GUI has in it's database you can force a 
refresh by executing the below command on the GUI node:
 
/usr/lpp/mmfs/gui/cli/runtask OS_DETECT --debug
 
2.) If it is not the one that's shown in the returned performance data you 
have to restart the pmsensor service on the nodes:
 
systemctl restart pmsensors
 

Mit freundlichen Grüßen / Kind regards

Hi Matthias,
 
Not sure if this will help but we had a very similar issue with the GUI 
not showing performance data, like you we have separate networks for the 
gpfs data traffic and management/admin traffic. 
 
For some reason when we put the full FQDN of the node into the “hostname” 
field (it’s blank by default) of the pmsensors cfg file on that node and 
restarted pmsensors – the gui started showing performance data for that 
node.
 
We ended up removing the auto config for pmsensors from all of our client 
nodes, then manually configured pmsensors with a custom cfg file on each 
node.
 
It’s probably not the same for you, but might be worth trying out.
 
Thanks
Neil

Hi at all,

when I install the gui without a separate network for the admin commands 
the gui works. But when I split the networks the gui tells me in the 
brower:

Performance collector did not return any data.

All the services like pmsensors, pmcollector, postgresql are running. The 
firewall is disabled.

Any idea for me or some information more needed?

Many thanks in advance!

Matthias
