[monit-dev] Suggestion: file descriptor count

[Brian Candler]

I have a suggestion for a new process resource test: the number of open file
descriptors a process has.

We currently have a knocked-together shell script which does

  ls /proc/<pid>/fd | wc -l

and compares this to a threshold. If we could use monit to do this, it would
give a much cleaner approach.

I don't know if there's a better way (more efficient or more portable) to
collect this data though.

Cheers,

Brian.
