I do not seem able to get decent performance from my libre install. EIther using CRON or the poller.service.
I am currently managing 832 devices. 3 pollers.
See my build information;
I have offboard SQL - ANy suggestions to what I am doing wrong?
Maybe you are hitting SQL max connections?
Or your RRD/SQL server is having a disk I/O issue?
With any tweaks I make I just seem to make it worse.
