Hardware Resources

[scott.barnes]

Hi,

I'm having an ongoing discussion with our hardware providers. We've been using the following metric to measure server performance accross a 6 node load balanced tier running a web application. The metric reaches 100% just before an application crash so I'm confident it is telling us something useful. Can you please give me a technical explanation of what the following metric is showing us;

Application Infrastructure Performance > Tier > Individual Nodes > Node > Hardware Resources > CPU%

I believe the .NET agent collects the Windows performance counter "System: %Total Processor Time" and reports it to the Controller as Application Infrastructure Performance|<Tier>|Individual Nodes|<Node>|Hardware Resources|CPU|%Busy

See https://docs.microsoft.com/en-us/sql/relational-databases/performance-monitor/monitor-cpu-usage for details.
