Hello All,
after upgrading checkmk version from 2.1 to 2.3 the graphs are not more shown:

The screen is being taken in a remote site, on the central site i got this error instead, while trying to view a graph:

Any guess on how to resolve the issue or why it is happening ?

Thanks,
Davide

Unclear as you have not given any detail as to the way (path) you followed upgrading from 2.1.0p15 → 2.3.0p27

Did you follow the recommended intermediate upgrades as discussed in this post ?

Hi Michael,
yes, I upgraded to the latest 2.1 version then to the latest 2.2 version and at the end to the latest 2.3.
Unfortunately, at the time, the latest version of the 2.3 was the p13 and a couple of weeks we applied the update this warning come out:

Today, I have updated the remote site to the patch 27, but this does not resolved the issue.
I still have the backup of the remote site at version 2.2.0p31, should i roll back and then update directly to the 2.3.0p27 ?

I want to add that the central site is a 2.2.0p31 and the graph of host managed directly by this site are showed and rendered correctly.
The strange thing, is that a couple o months ago we created a new site with 2.3.0.p23 from fresh installation and in this site the graphs are not rendered correctly, so is it legit to assume that there is some incompatibility between central and remote site versions ?

I am unfortunately unable to provide you with an answer to this, as i do not use a distributed setup.
Also the warning/issue you are describing was at a time where i was still trying to solve own setup issues which kept me from upgrading my setup at that time.

I do not recall me - when transferring from 2.2 → 2.3 that i did take this intermediate step, maybe i just got lucky ?

Update,
i have just downgraded the remote site to the central site version through the command line, (not from backup) and now i can view correctly graphs both from remote site and central site.

Since i have about 50 remote site, it is less expensive to just update the central site to the 2.3.

Even if different major release are supported (Distributed monitoring - Scaling and distributing Checkmk) i believe that not every feature is available.
PS. i have rolled back the central site due to a problem with apache, there was an abnourmous number of session opened which casued an elevated CPU usage and the impossibility to log to the dashboard.
Now i will retry the upgrade on the central site to a different version than before setting a limit to the maximum numbero of apache connection available.

Thanks,
Davide

For as far as i read up (after having seen your issue, and for others who read it, please correct me on it as i have limited insight in a/the situation) .

[ removed] - i stand corrected by @aeckstein - thankyou for giving me clarification

No, this is wrong. Please Read the Upgrade guide. Remotes first and the the central site last.
