Hi,
fresh install of 26.1_4, I did some configuration and enabled data gathering for RRDs.
In the syslog I find tons of:
Quote/usr/local/opnsense/scripts/health/updaterrd.php: The command </usr/local/bin/rrdtool create '/var/db/rrd/ntpd.rrd' --step 0 DS:'offset:GAUGE:120:-1000:1000' DS:'sjit:GAUGE:120:0:1000' DS:'cjit:GAUGE:120:0:1000' DS:'wander:GAUGE:120:0:1000' DS:'freq:GAUGE:120:0:1000' DS:'disp:GAUGE:120:0:1000' RRA:'MIN:0.5:1:1200' RRA:'MIN:0.5:5:720' RRA:'MIN:0.5:60:1860' RRA:'MIN:0.5:1440:2284' RRA:'AVERAGE:0.5:1:1200' RRA:'AVERAGE:0.5:5:720' RRA:'AVERAGE:0.5:60:1860' RRA:'AVERAGE:0.5:1440:2284' RRA:'MAX:0.5:1:1200' RRA:'MAX:0.5:5:720' RRA:'MAX:0.5:60:1860' RRA:'MAX:0.5:1440:2284'> returned exit code 1 and the output was "ERROR: step size: value must be positive"
Basically no single RRD is created, of course creation with a stepsize of
0 fails.
Is this a known bug or a feature to save some disk space? ;-)
I don't think/see the bit of configuration I did on top of the fresh install caused this.
After I created all of the databases with a (guessed) stepsize of 60 the errors stopped.
Best wishes
Hello
You can try that in ssh
# opnsense-patch 6933841
and reboot
Worked for me
opnsense-patch 6933841 worked for me as well on 261_4 stopping frequent syslog messages about step size.
