Question Disk IOPS and data graphs missing

[Crim]

Server operating system version

Ubuntu 22.04.4 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.59 Update #2

On one of my servers the disk IOPS and data graphs are missing, how can I add these? Is there some kind of configuration file which I can compare?

Server 1 (without IOPS and data graphs, only utilization):



Server 2 (with IOPS and data graphs)

When you click the settings button in Monitoring and select the Thresholds option you'll find all the available monitoring graphs. Including IOPS, listed under the Disk header.

I don't see IOPS on this server:



On my second server I do see IOPS:



Both are running Ubuntu 22.04.4 LTS / Plesk Obsidian 18.0.59 Update #2 with the same software RAID1 setup.

Same provider?

2 dedicated servers at the same provider.

Hmm, I am not sure why that is. You could try to re-install the monitoring and Grafana extensions to see IOPS pops up as a option after ...

Would I lose all my historic data by doing this?

 

[Kaspar@Plesk]

I am not completely sure. On my test server historic data was saved (ie not deleted) and still accessible after re-installation of the extensions. But can't grantee anything.

I have tried to remove and reinstall the Monitoring extension a couple of times (the historic data is kept) but I don't get the disk IOPS graphs. Is there a way to add them manually?
