Dear Mr.Scott
I could have some results with Formula dataSource after changing my expressions .
My Expression : $ssCpuIdle+$ssCpuSystem
But when i create a new Calculate_Perfomance DataSource and write the same expression , when i do the TEST AGIANST MY DEVICE . i,ll have the following result :
Preparing Command...
Executing command $ZENHOME/libexec/ against 192.168.1.107
/bin/sh: /opt/zenoss/libexec/: is a directory
DONE in 0 seconds
Did i miss any configuration ?
