I'm trying to work out how I can get hobbit to alert me when a process

have NFS problems that cause processes such as df to hang due to stale
mounts and I'd like tp pick these up sooner rather than later.
Wouldn't it be easier to just scan the logfile for NFS timeout errors?
Hobbit doesn't track the lifetime of a process, and I would think this
would be very bothersome to setup because you'd have to exclude long-
living daemon processes.

By default, under RHEL (most of) the files under /var/log are owned by,
and only readable by, root. I'm still deciding whether or not to allow
hobbit to read the log files. I do think that there are other cases
where monitoring how long a process exists is useful.
I was thinking that this could be done by adding a new flag to 'PROC' in
hobbit-clients.cfg. Something like:
PROC processname minimumcount maximumcount color [TRACK=id] [TEXT=text]
[RUNTIME=seconds]
Example, alert if a 'df' has existed for more 60 seconds
HOST foo
PROC df RUNTIME=60
I started hacking but my C fu is weak.
