Hi,
Anybody know how the graph get’s cleared for all the hosts all of a sudden?. I can’t see any graph data before Nov 1, 2019.
There was no updates / changes done to CheckMK for a long time. I am running on 1.5.0p13 for quite a long time now.
Regards,
Anil
Hi Anil,
This can only happen if someone is removing your RRD files and the system generated new RRD files.
It looks if someone created a cron job running on the first of November and deleting all RRD files.
You can check inside your site with a “cron -l” to see if there is something defined to run at the time your graphs are starting.
Best regards
Andreas

Hello Andreas,
Thanks for the reply. I have checked the cron & bash history. Couldn’t see any deletions matching to date when the graphs disappeared.

Hi Anil,
do you use the enterprise edition or the RAW?
If it is the enterprise please take at look at the folder “~/var/check_mk/rrd/”
This should hold the RRD files if there are no files inside your pnp4nagios folder.
Best regards
Andreas

Hello Andreas,
Thanks for the reply. I have checked the cron & bash history. Couldn’t see any deletions matching to date when the graphs disappeared.
Cronjob:-
Once a day, at 00:30 cleanup old rrd files not touched for 30 days …
30 0 * * * find ${OMD_ROOT}/var/pnp4nagios/perfdata -name “*.rrd” -mtime +30 -exec rm {} +
Once a day, at 00:35 delete old folders if they won’t be touched for 30 days … remove deleted hosts
35 0 * * * find ${OMD_ROOT}/var/pnp4nagios/perfdata -type d -mtime +30 -exec rm -rf {} +
But even if I go to /opt/omd/sites/<site_name>/var/pnp4nagios/perfdata/ , I can see only one rrd file which is dated today.
Dec 3 01:29 _HOST__rountriptime.rrd
Do you know where exactly it stores old rrd files?.
Regards,
Anil

Hello Andreas,
Again thanks for your reply.
We are using the RAW edition and I can see RRD files inside pnp4nagios. Also there is no “~/var/check_mk/rrd /” folder exists.
OMD[XXX]:~/var$ du -sch *
751M check_mk
144K dokuwiki
0 icinga
42M log
8.0K mkeventd
4.0K monitoring-plugins
2.2G nagios
8.0K nagvis
63G pnp4nagios
4.3G rrdcached
268K ssl
244K tmp
4.0K www
70G total
OMD[XXX]:~/var$
But as I said earlier, I see only
one rrd file for each check and it’s just 380k size.
OMD[XXX]:~/var/pnp4nagios/perfdata/$ du -sch TCP_Connections_BOUND.rrd
380K TCP_Connections_BOUND.rrd
380K total
Not sure if check_mk will move old RRD data to some other location.

Anil
