Thanks John. Crud, I guess I did forget the OS and all the other stuff that Jared is going to smack me with. Arggg! Okay, here goes: Linux RHEL 4.x, monitored by OEM (agent, OMS, and Repo all same rev). Repo and OMS both on Linux RH 4.x.

We've also got Tru64 5.x, but OEM 10g seems to have lots of troubles with advfs, so I've given up on that.

> Anyone have a good way of dealing with this? Should I create user
metric to pull in "vmstat" buff and cache values, used to subtract from used memory to get a more real picture? Seems like a dumb fix but I can't come up with any other way. I know managment won't understand that just because memory shows as 99% used all the time its really not.

You did not mention the OS platform, but I am guessing *nix. In that case, configure sar (if not already configured) - you will then not need to poll from vmstat. Depending on your OS, sar will be able to provide this information.
