Reading through the following three links will give you a great insight into using esxtop and vscsiStats.
Identify hot keys and fields used with resxtop/esxtop
See vSphere CLI Referencesection for esxtop
Identify fields used with vscsiStats
See vSphere CLI Referencesection for vscsiStats.
Configure esxtop/resxtop custom profiles
- Load esxtop
- Use hot keys to configure how you would like.
- ‘f’ will add and remove fields
- ‘o’ will change the order
- other hot keys will give you settings specific to that view.
- ‘W’ will save the settings to a new config file
- Next time you load esxtop use the ‘-c’ option to specify a configuration file
Determine use cases for and apply esxtop/resxtop Interactive, Batch and Replay modes
- Batch mode allows collection that will be captured to a file.
- esxtop -b > file.csv
- Esxtop will replay resource utilization stats that were collected using the vm-support command
- The capture from the vm-support command would have been generated by the following command
- vm-support -s -d duration -I interval
- You would then unzip/untar this for esxtop to use it.
- esxtop -R <path to dir>
Use vscsiStats to gather storage performance data
Given esxtop/resxtop output, identify relative performance data for capacity planning purposes
Again check out the links mentioned above in this section. They are a must read and will be a great guide in helping to identify performance related issues.
