Hi, is there a way to monitor file handle usage - how many open files against the maximum allowed, by any chance? - just had a request from a user for this and couldn't find a reference in the documentation or the Google thing.
Regards,
Nick
You'll likely need to write your own test based on this (assuming this is linux):

Sorry, it will be most likely used under Solaris 10/11.

Have an external that uses "sar" to figure out the number of open file handles. It has stanzas for Linux and HPUX; if your Solaris box has sar then should be able to add a Solaris stanza.
Basically uses "sar -v 5 2" and processes the last line; 3rd field for linux, 8th field for hpux.
If you want the external, can send it to you off list. It may be malingering as a Big-Brother module on the Dell/Quest/Big-Brother/defunct-deadcat repository. You may also find other modules there that can be modified for your requirements.

It's been a long time since I worked on Solaris but there might even be a way to do it with dtrace. There was a link for doing something similar using lsof but that required a bit more work.

googling a bit more shows that the /proc filesystem is available on Solaris and there is also the pfiles command.

If you have /proc available, then check if you have /proc/sys/fs/file-nr. If you do then should be able to get the value using:
cat /proc/sys/fs/file-nr
This "should". ahemm.... be OS agnostic.

Nope, Solaris does not put non-process-related info in /proc (no /proc/sys on Solaris).
The following _might_ be what's wanted, but keep in mind that the maximum isn't necessarily a hard limit; it could grow as needed.
kstat -p 'unix:0:file_cache:buf_[im]*'
No special privileges needed (kstats are readable by anyone), and it will even work in a zone; but the info will apply to the entire OS, and not be specific to the zone (no sane way to do that, AFAIK!).
Example:
$ kstat -p 'unix:0:file_cache:buf_[im]*'
unix:0:file_cache:buf_inuse 1248
unix:0:file_cache:buf_max 2320
That was run on Solaris 10 / SPARC; but it works similarly on 9 and 11; I don't have anything available older than Solaris 9 to try it on.
