After integrating Telegraf to an SD-WAN Gateway, you can collect the counters from the configured Input and export the data to the Output plugin.

The following table lists the supported Counters that can exported from an SD-WAN Gateway.

num_nsd_paths_up/down Number of NSD tunnels in UP/DOWN state in the Gateway. Global 4.3.0
num_paths_INITIAL

Number of tunnels in INITIAL state.

INITIAL state indicates that the Edge just initiated a tunnel request to the Gateway.

Global 4.3.0
IPv4, IPv6 4.5.0

num_paths_MEASURING_TX_BW

num_paths_MEASURING_RX_BW

After initiating a tunnel request, tx and rx bandwidth will be measured for the tunnels from Edge to Gateway before moving to STABLE state. The number of tunnels for which tx and rx bandwidth is measured is tracked under the respective counters. Global 4.3.0
IPv4, IPv6 4.5.0
num_paths_STABLE

Number of tunnels in STABLE state.

STABLE state indicates that the tunnel is established between edge and gateway and the tunnel is stable.

To find the percentage of stable tunnels, multiply the number of stable tunnels by 100 and then divide that value by total number of tunnels.

Global 4.3.0
IPv4, IPv6 4.5.0
num_paths_UNSTABLE

Number of tunnels in UNSTABLE state.

If the loss, latency and jitter values exceed the defined threshold, the tunnel moves to UNSTABLE state.

To find the percentage of unstable tunnels, multiply the number of unstable tunnels by 100 and then divide that value by total number of tunnels.

Global 4.3.0
IPv4, IPv6 4.5.0
num_paths_QUIET If no packets are received in the path for a defined time interval, path transitions to QUIET state and the number of such paths are tracked here. Global 4.3.0
