Hi all,

from one day to another i'm suddenly unable to get graphics when clicking on "Show performance chart" in my services - it always results (in each case) with a "no data".

Restarting the omd does not help, neither restarting the whole system...
What can i do? Is there a description somewhere to follow in such cases?

I am on OMD 5.30-labs-edition with Thruk 3.12, host is OK (no load, enough free hdd space)

Thanks for any help!
Joe

There are many wheels involved here, which graphing and database do you use?

Hello jstark1,

thank you for your help!
The answer to the above command is:

INFLUXDB: on
NAGFLUX: on
PNP4NAGIOS: off

influx

if i execute the command i get answers until the date since it stops to show graphs (21.11.2024), after that i get no results:

`

`

Additionally i recognized today, that since 10 days the partitons free space is rapidly decreasing!
It seems that there is a problem somewhere with "cleaning up" data?!
This is remarkable because the system is up for 3 years now and there have never been such a problem.

ok, nagflux is not writing data to the influxdb. I would check etc/mod-gearman/server.cfg for "perdata=grafana_data", and ModGearman section in etc/nagflux/config.gcfg.
See https://omd.consol.de/docs/omd/howtos/grafana/

some troubleshooting commands:

omd diff etc/mod-gearman/server.cfg
omd diff etc/nagflux/config.gcfg
gearman_top -b | grep grafana_data

But InfluxDB thinks so. Same error message here: https://community.influxdata.com/t/writing-on-influxdb-stopped-no-space-on-device/2328

OK, understand.
i rebooted the host now and the error with "no space left on device" disappeared: good.
But data are still not available, the log var/log/nagflux/nagflux.log now says:

I am sorry, it is not possible to solve your problem based on some log snippets and try this, try that,....
The nagflux.log is full of error messages and to me it looks like the influxdb is damaged (provided the perfoormance data are correct and not the reason for the errors)
You should find some help from the influxdb developers, but we (as authors of OMD) are only users ourselves and can't help here.

I agree with Gerhard, your influxdb is broken. Perhaps the influx_inspect can help.
A check like:

influx_inspect verify -dir ~/var/influxdb

give me

Hello Jens,

thank you very much for your help!

If i run the command i only get lines with "Healthy" at the end and this summary:

...
var/influxdb/data/nagflux/autogen/984/000000074-000000003.tsm: healthy
var/influxdb/data/nagflux/autogen/992/000000027-000000002.tsm: healthy

Broken Blocks: 0 / 8139454, in 53.975394778s
...

So it seems to me that the db(s) are not broken, right?

Will it be helpful if you take a look at my system directly?

Joe

OK, after 4 weeks without graphs and no real help from influxdb i stop at this point with the idea, to repair anything.

Last question:
how can i reset influxdb (or omd) and go further with no historical data?

sni Dec 20, 2024
Maintainer

stop influxdb and remove everything in var/influxdb should reset the database.

airathere Dec 20, 2024
Author

OK. I did that and stopped omd completely to be sure, then deleted the whole var/influxdb
After starting OMD it tells me:

Doing 'start' on site mysite:
Starting influxdb...first run, waiting for initial _internal database..............OK
Running naemon configuration check... OK
Starting naemon...OK
Running apache configuration check... OK
Starting apache...OK
Starting nagflux...OK
Starting grafana...OK
Starting crontab...OK

after a few seconds i can see exactly the same errors in var/log/nagflux/nagflux.log than before!!

frustrating...
