Just looking at the source for the filesystem collector in the Node
Exporter, the detailed errors in case of a failed statfs() are logged at
debug level, so you'd have to set --log.level=debug to see that:

Adding to this, I noticed something very strange. I am seeing that
node_filesystem_device_error gives 1, but when I login into the servers,
everything seems to be fine with the NFS mount. Even the statfs call is
successful.
Is this a bug? If not, how to know the reason because of which
node_fil
2 matches
