I.e. instead of:
$ lscgroup cpu:/
cpu:///
cpu:///system
show:
$ lscgroup cpu:/
cpu:/
cpu:/system

All the data continuously generated in your IT infrastructure
contains a definitive record of customers, application performance,
security threats, fraudulent activity, and more. Splunk takes this
data and makes sense of it. IT sense. And common sense.
