Hi Folks,
Following last nights update I’m having a problem with the Proxmox App.
From the main menu if I choose ‘Apps/Proxmox’ I can still see my clusters and the VPS they are running. However hovering over a VPS displays nothing and clicking on a link results in a blank page.
If I look at the node server hosting the VPS, under APPS none of the VPS are now listed.
Any help much appreciated.
Cheers
Clear the cache in your browser
Thanks for the reply,
Sorry I should have said I’ve already tried clearing the cache. I also tried testing from a completely new client machine/browser that had not been used before. In both cases the results are the same, the page title appears followed by the cluster title then nothing.
Add /debug to your url and see if it gives any output
Ok from the Main Menu I choose Apps/Proxmox, I then select one of the listed VPS and add /debug to the end. This gives me a blank page with options for SQL and PHP on the bottom. Selecting either brings up a dialog.
SQL -> 0 total SQL queries run.
PHP -> 0 total PHP issues / errors.
Repeating for the Device/Apps tab returns the same.
Hmm, check logs/librenms.org and see if there are any errors in there after visiting the page.
Ok I refreshed/opened the offending pages a number of times then captured the last few lines from each logfile. Nothing jumps out, the last logs in the error log file were from the day before.
I also have a couple more LibreNMS installs, each is created from the published Centos 7 VMDK and each runs on and monitors a local ProxMox cluster. In all cases the same ‘issue’ has occurred so whatever has happened is consistent.

That timezone notice has been fixed, your install isn’t up to date, run ./daily.sh
I think that’s a hang over from earlier. I’ve manually run daily.sh just in case but checking the log everything looks up-to-date:

Could it be a php out of memory issue?

Sorry for the delay in responding, too many things to do!
So last nights update fixed 90% of the ProxMox Issues, I say 90% as the graphs for the VPS are now shown correctly when you select one however the ‘hover’ pop up is still missing (perhaps its supposed to be).
So whatever the issue it seems it was a codebase one not an environment, unless someone wants to correct me.
Thanks
