[Xymon] File Handles

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.
