Memory usage percent

Is there any way to know or alert for Memory usage percent instead of memory usage size?Do I need to create a new plugin to calculate it?or this is possible without any new plugins?

can anyone help me to make an alert when free memory is less than 10%?

Is there any idea about how to make a new plugin to fix this?

Hi,

this topic has been discussed several times. To put it in a nutshell:
No it's not possible right to to fire an alert when the amount of free memory reaches a certain percentage value.
Writing a new plugin is not a good idea i think. In my opinion the alert facility should calculate the values.
Maybe it's a good idea to request that function

Cheers,
Mirko

Back in the day we did have a "Derived Measurement" feature where you could define this using existing values as Mirko's suggesting. Not sure if that'll return anytime soon, in the meantime I've added these to the sigar api: http://jira.hyperic.com/browse/SIGAR-92

Still need to upgrade the sigar version in HQ and expose via the system plugin, but that should be available soon.
