Parts of the graphs are missing

[zavt]

Hi everyone ,

I recently installed the cacti with version v1.2.25 (rhel 9.3) and import the old db version of cacti, v0.8.8b (Debian 7). My main problem it's that there are missing parts of the graphs. Differs on time and servers. I attached a snapshot to be more clear. Also i'am not a expertise in cacti. Anyone has face this issue?

Look into your cacti.log, and give the system stat line and other error or warning, like a poller error

[zavt]

I already looked into cacti.log. I can see errors entries but it's related to a few devices (less than 10).

However, related to warning, i have a lot of entries:

Can you give the ' SYSTEM STATS' from the log

Your poller doesn't finish in time sometimes. It is in forum very often. Try to find poller overrun, gaps in graphs, ...

Try to upgrade to 1.2.26, spine too. If I remember correctly, we fixed few things about poller.

[zavt]

I will look in the forum for poller overrun and gaps in graphs. Then, the last resort, i will upgrade to version 1.2.26.
