+ Performance and Fault Management
+=================================
+
+|prod| provides a number of tools to allow system administrators to manage
+performance and troubleshoot system issues.
+
+Performance Management
+----------------------
+
+|prod| utilizes collectd ( https://collectd.org/ ) to capture the following
+platform statistics and to generate threshold events based on
+these statistics:
+
+-    CPU Usage of Platform Cores of |prod| hosts
+
+-    Platform Memory Usage of |prod| hosts
+
+-    Platform File Systems Usage 
+
+-    Platform Interface Usage
+
+-    PTP Clock Skew Monitor
+
+Any collectd threshold events trigger |prod| fault management Set/Clear
+Customer Alarms.
+
+Fault Management
+----------------
