Esxi – Add historical stats to go over the 1 hour limit


The free version of esxi only allows you to view 1 hour of data through the vsphere tool.

To enable further historical stats simply amend the configuration file located within /etc/vmware/hostd directory. Amend the historical stats figure from false to true.

vi /etc/vmware/hostd/config.xml
<!-- Enable historical stats collection -->
<historicalStatsEnabled> true </historicalStatsEnabled>

pssst…ps


ps is another great facility in linux. It allows you to monitor what processes are running on a server. Using the below command we can identify the top CPU hungry processes.
ps

ps -eo pcpu,pid,user,args | sort -k 1 -r | head -10

result
