[collectd] plugin tail as source for smartcl tmp

[Bruno Friedmann]

I've seen the contrib exec-smartctl but my smartctld also log into syslog the Temp change.
so i think tail plugin would be more appropriate. Right ?

I think this exercice can also complete the wiki page about tail plugin.

Context : two drive to monitor sda & sdb
smartctld is logging temp change in /var/log/messages when it appear

Regex : (this is not my favorite & master domain ... :-)

With this grep  -e "smartd.*194.*[0-9]$" /var/log/messages
I can get all lines of

But after digging conf, website and wiki I can figure out how to write the RegExp inside conf
to get a gauge
