Composition of dashboards

Dashboard	Panel	Purpose
ePDG Overview	10	Service availability, connection success rate, number of active sessions, SWu/SWm/S2b status, interface bandwidth
IKEv2 Details	10	Mes per second by type, histogram of request duration, delay in the 95th percentile, error by type, IKE SA life cycle
GTP Details	8	GTPv2-C PGW messages, retransmissions, cause code errors, GTP-U (uplink/downlink) carriers
Diameter Details	7	Number of application messages (SWm/SWx/S6b), duration of requests, state of watchdog timer, distribution of result codes, chronology of connection states
