Memory Usage Not Accurate

[Zolaikha Hammad]

Hi All,

I am new to grafana and I am trying to scrape system metrics into promethues using windows_exporter and show them in grafana dashboard. I want to show memory usage by per process bu the value is not accurate. I converted the value into KBs by dividing the metrics with 1024. Here's my query 

topk(5,sum by( process, process_id) (windows_process_working_set{instance=~"$server.*",job=~"$job"})/1024 ).

If anyone knows the query to show memory usage by process please let me know 

Thanks and Regards,
Zolaikha
