I am trying to create an alert when 90% of RAM is used.
I have determined that Committed bytes is the amount of RAM in use but I don't know how to get total RAM.
I am NOT trying to find memory but a percentage of physical ram in use. Thanks
the real question is how do you take the information about RAM?
if you use the Splunk_TA_Windows ( https://splunkbase.splunk.com/app/742/ ), it can extract many counters:
in this way you can calculate the percentage of used memory on total.
In addition, in the counters there's also "% Committed Bytes In Use" that directly answers to your question.
I appreciate your quick response. Is Available MBytes RAM or memory ? I am trying to calculate RAM.
