Hello - My Libre was working perfectly since initial setup about 30 days or so. Today I added about 10 more hosts to bring it to 40 and some time while adding those hosts it just stopped graphing and I have no idea why. My validate config looks great! When I look at the logs it appears to be polling devices like crazy which I think is good however there is no graph data for some unknown reason. I rebooted the server but no luck. Again the only change is adding more devices.
I did figure out the problem. My workers seconds were way out of balance. I added more CPU and then increased the “Poller Workers” under Poller settings in the GUi to resolve the issue.
I am curious however when you mention RRDCache. Is there a way to check if I am using that and if it is healthy? Thank you
