What is best VSphere performance monitor and troubleshooting approach for CPU and high I/O?

Hello,

I’m running vSphere 6.7 and a VM which is my SCOM Server is having high CPU and I/O. How can I report performance on this server and attempt to isolate the service for which is pegging resources? How would an expert approach this scenario?

Thank you so much!

yes sir...hey Andrew, can you elaborate on solution? thank you!
So you have vCenter Server ?

Then you have all metrics recorded.

So what is your environment, host, cpu, memory, disk, network...

what have you allocated to the VM ?

what is the underlying storage ?

The steps are all listed in my article.... to find where the bottleneck exists...

1. Check and correct CPU utilization: CPU Performance Analysis and Monitoring

2. Identify memory bottlenecks and remove: Memory Performance Analysis and Monitoring

3. Characterize storage performance and correct: Storage Performance Analysis and Monitoring

4. Understand and improve the network utilization profile: Network Performance Analysis and Monitoring

but we need to know what your environment is first.....
Thank you Andrew!
