As an administrator, it is ideal to get familiar with built-in tools for Windows. My main go-to’s are Resmon and Perfmon. Resmon is good for what is happening now and Perfmon is good for a collection over time (although it can be used for in-depth real time metrics). I usually do these three steps when someone reports “slowness” on a server:
RDP to the server and open Task Manager. Check current usage stats. Open Resmon (Run – resmon) and let it run for a little bit, monitor results.
Open Event Viewer (eventvwr.msc) and check the logs during the time frame the user specified.
Open Perfmon and create a Data Collector Set
Data Collector Sets- User Defined – New – Name it
Choose Create from Template – System Performance – Finish the wizard using common judgement.
At the end, choose “Open Properties”
Go to Schedule Tab and set the schedule to the time the user said the issue was.
