How do monitor the usage of file descriptors on a system?

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I want to watch the number of file descriptors being used at any given time on a machine running Solaris 2.5.1. Is there any way to do this? Is it possible to find out what processes are responsible for using up the file descriptors? Thanks

Perl itself does not do much in the way of deep OS level monitoring, mostly because its completely impossible to maintain. But, I believe some variation of lsof (from sunsite) run as root will be your easiest route to finding it. http:More info here -- Jay "Yohimbe" Thorne, alpha geek for UserFriendly	[reply]

As mentioned above, this isn't a Perl problem. But you shood look for the lsof tool. It'll do exactly what you want (it tells you what processes have what filehandles open and a whole lot more).	[reply]
