A tunnel is established over a link and has communication with a peer. A peer can be a Gateway (edge to Cloud traffic), Hub (edge to data center traffic) or Edge (dynamic edge-to-edge VPN traffic). The Tunnel Stats template captures the stats of a tunnel and it is sent every one minute. The linkUUID field lists the link established for the tunnel. The interface Index field says to which peer it is communicating.

Difference between Tunnel and Path

Path is a unidirectional entity and tunnel is bi-directional. TX and RX paths make up a tunnel.

Note:
  • Only connected tunnels will be exported. If a tunnel goes DEAD, this tunnel’s stats will not be exported from the next export interval. For example: if the tunnel stats template export interval is 300 seconds and the tunnel was exported at time t1 and tunnel goes down at t1+100. Stats between (t1 and t1+100) will be exported at t1+300. And from the next interval, this tunnel’s stats will not be exported since the tunnel has gone DEAD.
  • Number of tunnels down events will be exported as part of tunnel stats template.
  • Formula for Loss computation:
    • TX Loss Percent = ((packetsLostDeltaTxCount) / (packetsLostDeltaTxCount + packetsLostCompDeltaTxCount)) * 100
    • RX Loss Percent = ((packetsLostDeltaRxCount) / (packetsLostDeltaRxCount + packetsLostCompDeltaRxCount)) * 100
