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.

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

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.

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.

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

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
