Sitescope VM monitoring
Hi Sitescope experts,
I often heard from my colleagues that sitescope doesn't report accurate matrix from VMWare VMs. Is this true , are many customers experiencing the same and have differences in data reported by VMware vs Sitescope?
I would highly appreciate if sitescope experts throw some lights with latest updates related to current versions of Sitescopes that are used in performance testing.
Quoting from the SiteScope Monitor Reference Guide:
Inaccurate Performance Analysis Using Perfmon to Monitor CPU on VMware
Problem: SiteScope uses Perfmon to connect to the operating system of the VMware virtual
machine and query it for CPU usage of the virtual host. When used over a period of time to monitor
CPU on VMware, Perfmon provides inaccurate performance analysis.
Solution: VMware resolved this issue by integrating virtual machine performance counters such as
CPU and memory into Perfmon for Microsoft Windows guest operating systems when VMware
Tools is installed.
I am attaching the guide to this thread, if you want to take a quick look to it. Please start on page 820.
