Graph not drawing frequently even get the value

[zexinfinite]

Hi folks,

I usually get the discontinuous graph, but there have value in legend and RRD command.
All of graph have same issue, and the result of validate.php is OK.

Does anyone faced same issue before?

I noticed the poller performance was unstable, and sometime the consumed worker seconds will bigger than maximum, so I try to increase poller from 16 to 48, then all of graph seems more stable.

hi,
I installed RRDcache and it resolved for me. I did about 2 years ago, so don’t remember how I did it. I just followed the on line help for it.

I’ve enabled RRDcache in the beginning, but the situation still getting worse since 2021.
I finally solved issue with increase CPU resource then added worker from 24 to 48.
