Keep Getting "collectd: rrdcached plugin: Failed to Connect RRDCached at unix...." errors in my syslog

Hi OMV forum,

I am posting today as I have tried a couple brief attempts to solved this issue to no avail.

I am continuously getting errors in my log for the rrdcached plugin. I looked at a couple posts in the forum and ran omv-firstaid to try solve but the issue persists.

This is the error message in my logs:

Code

collectd[1405]: rrdcached plugin: Failed to connect to RRDCacheD at unix:/run/rrdcached.sock: Unable to connect to rrdcached: Connection refused (status=111)

I ran omv-firstaid and did "Check RRD database" which gives me about 76 requests to remove rrd files that contain timestamps in the future? Not sure what is going on (probably too much of a newb) but even when I delete them with omv-firstaid they still seem to appear if I run the tool again.

Any help is appreciated, I am running OMV version 5.6.26-1 (Usul)

Thank you!

Check the time on the server and post the output of

systemctl status chrony

thanks for the help macom

here is the output of the command, the time on the server looks to be correct when I run timedatectl

Yes, looks fine. I was mislead anyway.

Try to disable and enable monitoring in the GUI of OMV and check if there are any error messages.

Ok I gave that a try, will give it a little time and see if the issue clears up, then report back.

looks like that did the trick so far. As always, appreciate the help macom
