I can help with the first one as I had the issue a few weeks ago. The answer from support is below, verbatim.<br>
<br>
<span style="font-family:"Arial",sans-serif">---------------------------------------------------------------------------------------------------------------------------------------------<br>
<br>
When trying to resolve the IP-Address in the JAVA code the first entry entry in the list is returned.<br>
Just localhost was expected for this. If the order is other way around and the list starts with<br>
localhost.localdomain, the GUI unfortunately cannot resolve the real node name and will fail with<br>
the message seen in the log files.<br>
Thus I assume that this is the case for your customer.<br>
<br>
it seems that our code it not as tolerant as it should be for the <i>localhost</i> definitions in<br>
the <i>/etc/hosts</i> file on the GUI node.<br>
We need to change this in our code to handle accordingly.<br>
<br>
Please let the customer adjust this entry and place localhost at the top of the list.<br>
After this the task should run successful and the state should be OK again for the pm_collector.<br>
---------------------------------------------------------------------------------------------------------------------------------------------<br>

checking the GUI nodes /etc/hosts it shows actually<br>

Subject:</b> [gpfsug-discuss] Pmsensors and gui<br>
<br>
Hi,<br>
<br>
I have a couple of a problems with the GUI and the stats data in there …<br>
<br>
First, on the gui node, I am getting “The following GUI refresh task(s) failed: PM_MONITOR”, looking at the log for this:<br>
<br>
PM_MONITOR * 2018-10-09 14:35:31 15ms failed RefreshTaskScheduler$1.run com.ibm.fscc.common.exceptions.FsccException: No entity found for NODE: null/localhost.localdomain<br>
<br>
Suggestions?<br>
<br>
Second, a bunch of my hosts have multiple NICs on different networks, they are joined to the cluster with the name hostname1-data, however the “primary” hostname of the host is “hostname”. I see summary stats information in the GUI which references the shortname
of the host, but when I click the host in the GUI, it claims no data – I assume because the GPFS hostname is the -data nama and pmsensors is using the primary hostname.<br>
