* SYNOPSIS
* sudo ./110provider_profile.d
*
* DESCRIPTION
* The profile provider has basically two kinds of probes:
* - profile probes fire on all CPUs each time period
* - tick probes fire only once each time period
* One can specify either a frequency or a time period.
*/
/*
* A profile probe is used with higher frequency to sample
* what is executing on the system.

/*
* A tick probe is used to fire once to stop data collection.
