Hello,
It is noticed that some Netapp storage volumes are reporting incorrect numbers on librenms. the snmp reporting data is correct. However, after poller calculation librenms somehow got it incorrectly.
here is the full capture of poller.
For example, volume /vol/backup data from snmp shows percentage 98% and 240008568KB(about 229GB)
available:
