I noticed something weird in central-broker-master.log :

Any help would be greatly appreciated ! Wishing you happy holidays if so

Figured out it was just punctual errors and the TCP connection is working.

RRD files are getting updated, other widgets are working as intended, for example :

Huh… It’s been 3 days of debugging and I can’t even get a clue of why it isn’t working. I’m starting to think I’ll have to start fresh and reinstall everything.

I would greatly appreciate any clue of what could be happening since I’ve ran out of ideas !

Hi @Yllake do you have enough space in /var/lib/centreon/metrics directory?

Can you check the //var/log/centreon-broker/central-rrd-master.log file?

Hi @Laurent ! Thanks for answering

I think I do have enough space available :

The ‘metrics-old’ folder is just a copy I made while trying to debug

As for central-rrd-master.log, everything seems fine except that one error I found :

“””

�core] /info] main: termination request received by process 405433
core] icore] wcore] ntcp] dinfo] TCP stream destroyed. Still 0 configured on a thread pool of 3 threads
ttcp] sdebug] Finishing to write data before closing the connection

“””

I tried reading rrd files and they seem to update according to the values I get in CentreonWeb.

How do you check rrd file? If you move to “Monitoring > Performances > Graphs” can you see them?

Same problem on version 23.04.5, Graphs were working yesterday and now they aren’t. “There’s no data”

I tried researching a bit about rrdtools, I learned that you can see the last value put into the file with 

rrdtool last 667.rrd

Anyway, no, I can’t see them anywhere, even when hovering over the graph Icon in ‘Regroupement par hôte’ unfortunately…

There it says “No data available for this period of time”

Hi, are you on Debian?

Where are the owner and groups of /var/log/centreon/rrdtool.log file?

ls -lah /var/log/centreon/rrdtool.log

Hello @Laurent ! Yes I run Centreon on Debian 11.

-rw-r--r-- 1 centreon centreon 0 15 juin  10:24 /var/log/centreon/rrdtool.log

It’s the same as other log files... Should the owner be centreon-engine or centreon-broker ?

I don’t want to hijack the thread but I have the same permissions

-rw-r--r-- 1 centreon centreon 0 jul  7 22:26 /var/log/centreon/rrdtool.log

Also at work I have the same issue with centreon, both using Debian 11.

-rw-r--r-- 1 centreon centreon 0 jul  7 22:26 /var/log/centreon/rrdtool.log

No worries, please participate as we seem to have the same issue and configuration.

Then could it be a RRD package issue ?

Ok can you change rights using:

chown www-data:www-data /var/log/centreon/centAcl.log
chown www-data:www-data /var/log/centreon/license-manager.log
chown www-data:www-data /var/log/centreon/login.log
chown www-data:www-data /var/log/centreon/rrdtool.log
chown www-data:www-data /var/log/centreon/sql-error.log

That solved it after restarting centreon !

Woah how come the logs permission influence the behavior of the graphs ? Alone, I could never have guessed

Thank you so much @Laurent ! @Net ping

Yes the solution also worked for me in both my lab and at work.

Thank you @Laurent and @Yllake
