+KPI Collection
+^^^^^^^^^^^^^^
+
+KPI collection is the process of sampling KPIs at multiple intervals to allow
+for investigation into anomalies during runtime. Some KPI intervals are
+adjustable. KPIs are collected from traffic generators and NFVI for the SUT.
+There is already some reporting in NSB available, but NSB collects all KPIs for
+analytics to process.
+
+Below is an example list of basic KPIs:
+* Throughput
+* Latency
+* Packet delay variation
+* Maximum establishment rate
+* Maximum tear-down rate
+* Maximum simultaneous number of sessions
+
+Of course, there can be many other KPIs that will be relevant for a specific
+NFVI, but in most cases these KPIs are enough to give you a basic picture of
+the SUT. NSB also uses :term:`collectd` in order to collect the KPIs. Currently
+the following collectd plug-ins are enabled for NSB testcases:
+
+* Libvirt
+* Interface stats
+* OvS events
+* vSwitch stats
+* Huge Pages
+* RAM
+* CPU usage
+* IntelĀ® PMU
+* Intel(r) RDT
