Hello,
Yesterday after 1 am my LibreNMS started sending alarms that all power supply voltages were out of parameters, on all servers in my network.
After reviewing the voltages (the information is downloaded from IPMI) it turned out that the limits were messed up.
On one of the servers I deleted the limits, ran a new scan, but the limits did not appear.
How can I fix this?
~$ ./validate.php
