Error parsing regexp: invalid or unsupported Perl syntax

[albech]

When trying to query filesystems different than '/' no data is received.

Expected behavior
It is expected to pass data back to Grafana for the different filesystems.

Screenshots
On this screenshot it is clear that some Perl Regex is failing and probably the cause of this issue.

Not sure if this is the same or not (error message looks similar). I have a web server with different partitions, and I can't get
data from /var/www, but all others work fine (/, /usr, /tmp). Error message from the query inspector is: error:"error parsing regexp: invalid or unsupported Perl syntax: (?w"

I have done a ghetto Regex fix, by changing the Application to the appropriate filesystem and the Item to /.*Total/ and /.*Used/ to avoid using /'s inside the Regex. Hope this will help some people around this bug intil a fix is committed.

That's a mistake in a filter parser, it parses regex in a wrong way (in your case filter is not a regex, but parser tries to parse it anyway).
