Re: monitoring network filesystem

[Martin Pala]

Hi Aleksander,

the feature is implemented in next Monit version (5.2), it allows to override 
default alert action when the monitored object doesn't exist. Syntax is as 
follows:

    check file with path /path/to/netfs/lost+found
       if failed existence for 5 cycles then exec "/path/to/scripts/mount.sh"


You can get the development version from svn:
http://code.google.com/p/monit/source/checkout

Regards,
Martin
