Description:
The duration to compute the "Status" of Windows processes is the bottle neck of the
processlist
monitor on Windows. This change delegates the evaluation of the thread status to the WMI query reducing the amount of data marshalled back to golang. On my dev box this reduced memory and cpu usage, the duration was reduced to about 30% of the original code.Link to Splunk idea:
