So I converted my kubernetes install from using the librenms cron to using dispatcher. I installed redis and everything ‘seems’ good however none of my rrd files are getting updated. I am also getting an error on the console of the dispatcher. I don’t know if this has anything do do with the rrd issue.

Your OS isn’t set to use UTF or something?
Good question. I’m running this in a container in k3s. The node is running Ubuntu 18.04.

Hi
Are some your graphs red. I installed 1.65 docker today on Ubuntu 18.04 using docker-compose.
Most of my graphs are red some aren’t graphing at all.
Thanks
possibly, your UI instance is not able to access the RRD directory. check the RRD Command & output of the Red graphs you are seeing.
Hi
Below is an example of what is happening
docker-compose exec --user librenms librenms php validate.php
