Overview

CPU Usage Check with Process Profiler is a Sensu Check that was built as an extension of the official check-cpu-usage check. At the time of this writing, it provides the same functionality as the original check-cpu-usage check, with the added benefit of providing a list of the 10 top resource intensive processes at the time that the check was carried out.
