Defines a new parameter <parameter_name> which is an average value for system performance counter <perf_counter_path> for the specified time period <period> (in seconds).
Syntax: <parameter_name>,“<perf_counter_path>”,<period>
For example, if you wish to receive average number of processor interrupts per second for last minute, you can define a new parameter “interrupts” as the following:
PerfCounter = interrupts,“\Processor(0)\Interrupts/sec”,60
Please note double quotes around performance counter path.
The parameter name (interrupts) is to be used as the item key when creating an item.
Samples for calculating average value will be taken every second.
You may run “typeperf -qx” to get list of all performance counters available in Windows.
