===== 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 |
