At long last! Fans of bobross (a.k.a "BobRoss", the user on Thwack, not to be confused with "RobBoss" the YouTube celebrity: The Joy of Whiteboarding with Rob Boss - Happy Network - YouTube) as well as sysadmins who want to see the "right" values for Linux RAM can use this Poller in place of the SolarWinds standard. Download it here:
This poller calculates RAM as: 1 – (memAvailReal / memTotalReal)
...rather than the SolarWinds calculation of: 1 - ((memAvailReal + memBuffer + memCache) / memTotalReal)
Using the new(ish) "Manage Pollers" option in NPM, you can apply this to any nodes you want, and have the "default" RAM values populated with this calculation.
