Reproduce:
go to free space for root folder in librenms:
-value reported by librenms: 3.39GB Free
-value reported by “df -h” on server: 3.1G Free
When I used poller to poll the server, the SNMP reported value to the libreNMS server, matches the byte count (raw) by df on the target server. So I don’t know why librenms is showing the wrong value.
I’m seeing this for multiple servers, so I suspect this is more likely to be on the libreNMS side. One of my servers even has a discrepancy in the realm of 700MB, so this is really concerning.
