Configure performance data collection

This topic discusses how to improve the performance of the vCenter server when you see performance issues during data collection.

You can limit the processing (reduce the memory and cpu load) on the vCenter server during data collection when you see performance issues with your vCenter server. How performance data is collected in the Splunk Add-on for VMware is specified in the file ta_vmware_collection.conf. The parameter perf_format_type is set to one of two modes:

• csv mode. The response from the ESXi host when collecting performance data is parsed by vCenter. Performance data is collected by the Splunk App for VMware, from vCenter, by default, using csv mode.
• normal mode. The response from the ESXi host when collecting performance data is parsed by the data collection nodes. This reduces the load on vCenter.

To change modes, edit a local version of etc/apps/Splunk_TA_vmware/default/ta_vmware_collection.conf, and change the value of perf_format_type to normal. Processing performance data is now done on the data collection node.
