The graphs stop every X amount of time

[Sergiolocuelo]

I have a few charts monitoring devices, I have the poller set to 5 minutes, but sometimes every 5 minutes no data is collected.

In the "Grap Utility View" of the graph I have shown the following appears:

I don't really understand it, I have this configuration done in the poller.

The cacti crontab is also configured to run every 5 minutes.

Logs - > filter SYSTEM STATS. You will see lines like this:
2021-06-17 13:11:33 - SYSTEM STATS: Time:93.1284 Method:spine Processes:3 Threads:15 Hosts:344 HostsPerProcess:115 DataSources:16365 RRDsProcessed:7261

Column "Time" says how log poller runs. Have you here time about 300 seconds? If Time is about 300 seconds, it seems that the poller does not have time to process all devices

This is what the logs show:

Looks like you have 2 cron jobs running. Maybe under different users

I have checked the directory "/etc/cron.d" and 2 files related to cacti, one of them is called "cacti" and another one "cacti.bk", this second one I created because I was testing with the original one.

The "cacti.bk" file is also executed even if it has a different name than the original one?

Code: Select all

-rw-r--r--. 1 root root 128 nov 12  2019 0hourly
-rw-r--r--  1 root root  77 jun 16 17:21 cacti
-rw-r--r--  1 root root  77 jun 16 09:19 cacti.bk
-rw-r--r--. 1 root root 108 abr  7 11:06 raid-check

I have to add that at the moment the graphs are printing well, what I have done is to change in the file "php.ini" this variable:

Code: Select all

max_execution_time = 300

And at the moment the graphs are printing well.
What does this variable mean?
Why changing this variable works fine?
Should I change something else?

The "cacti.bk" file is also executed even if it has a different name than the original one?

I seems that yes. Remove .bk file or comment all lines in file.
