Monitoring Server CPU performance
Since June 2008 i am monitoring some important performance values, one of them
being CPU usage. When i started using Microsoft Windows Server 2008 with
Hyper-V, i almost immediately felt the need to
have some sort of monitoring for the server and for each virtual machine that
runs on it. Using some
Powershell
code,
WMI
queries i managed to create a script that periodically stores performance
information into my
SQL Server.
Depending on the type of information these performance values are stored at
different intervals and kept in the SQL database for a specific time-period. For
example, CPU usage is only kept for 5 days, after that it will be deleted.
Information about percentage disk free space however, is kept much longer but it
also has a much longer interval: 1 day.
Gradually more and more pages will be added to show other performance values of
my server and virtual machines.
