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.
|number_of_edges||Number of Edges connected to the Gateway||Global|
|number_of_tunnels||Number of tunnels associated with the Gateway||Global|
|number_of_routes||Number of routes installed in the Gateway||Global|
|number_of_flows||Total number of active flows in the Gateway||Global|
|active_NAT_entries||Number of active NAT entries per peer.||Global|
|free_NAT_entries||Number of free shared memory entries assigned for NAT||Global|
|stale_NAT_entries||Number of stale NAT entries in the system. This tracks only the stale entries due to ref count leak.||Global|
|stale_tunnel_entries||Number of stale tunnel entries in the Gateway||Global|
|stale_peer_objects||Number of stale peer objects in the Gateway||Global|
|stale_flow_entries||Number of stale flow entries in the Gateway||Global|
|sched_drop||Packets dropped in scheduler due to the bandwidth limit||Global|
|flow_drop||Packets dropped due to flow lookup failure and flow creation failure||Global|
|route_drop||Packets dropped due to route lookup failure and route sanity failure. Routing control packets which are dropped due to exceptions are also accounted.||Global|
|nat_drop||Packets dropped due to NAT lookup failure and NAT creation failure||Global|
|over_capacity_drop||Packets dropped due to internal handoff queue limit drops and due to low packet buffers in the system||Global|
|vcmp_drop||VCMP control and data packet drops due to VCMP sanity checks and exceptions||Global|
|invalid_pkt_drop||Packets dropped due to invalid checksum, TTL, and invalid packet size||Global|
|misc_drop||Packets dropped due to other errors and exceptions||Global|
|num_nsd_paths_up/down||Number of NSD tunnels in UP/DOWN state in the Gateway||Global|
Number of tunnels in INITIAL state.
INITIAL state indicates that the Edge just initiated a tunnel request to the Gateway.
|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|
Number of tunnels in STABLE state.
STABLE state indicates that the tunnel is established between edge and gateway and the tunnel is stable.
Number of tunnels in UNSTABLE state.
If the loss, latency and jitter values exceed the defined threshold, the tunnel moves to UNSTABLE state.
Number of tunnels in UNUSABLE state.
If the loss, latency and jitter values exceed the defined threshold for UNUSABLE, the tunnel moves to UNUSABLE state.
|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|
|nat_cnt||Number of active NAT entries per Enterprise||Per Enterprise|
|route_cnt||Number of route entries installed in the Gateway per Enterprise||Per Enterprise|
|flow_cnt||Total number of active flows per Enterprise.||Per Enterprise|
|tx_packets||Number of packets transmitted from the Gateway||Per Enterprise, Edge Tunnel|
|tx_bytes||Number of bytes transmitted from the Gateway||Per Enterprise, Edge Tunnel|
|rx_packets||Number of packets received by the Gateway||Per Enterprise, Edge Tunnel|
|rx_bytes||Number of bytes received by the Gateway||Per Enterprise, Edge Tunnel|
|vc_queue_<queue_name>_len||Number of packets enqueued in each handoff queues listed in Capacity of Gateway Components||Global|
|vc_queue_<queue_name>_drop||Number of drops in each handoff queues listed in Capacity of Gateway Components||Global|
|dpdk_mbuf_pending||Number of buffers that are already processed and waiting to be freed||Global|
|dpdk_mbuf_locked_fail||Number of times the GET buffer operation fails while retrieving a buffer from the locked pool||Global|
|dpdk_mbuf_locked_free||Number of free buffers present in the locked pool||Global|
|dpdk_mbuf_pool_free||Number of free buffers||Global|
|Total number of RX mbuf allocation failures||Global|
|mbuf_low||Number of times the mbuf_low threshold is reached||Global|
|net_sch.pkt_cnt||Number of buffers used by Net Scheduler||Global|
|link_sch.pkt_cnt||Number of buffers used by Link Scheduler||Global|
|link_sch_cosq.pkt_cnt||Number of buffers used by Link Cos Scheduler||Global|
|mp.rt_pkts_stored||Number of buffers used by VCMP retransmit store||Global|
|mp.reseq_qlen||Number of buffers used for VCMP resequencing||Global|
|mp.jitter_pkt_bufs||Number of buffers used for VCMP jitter management||Global|
|ipfrag.current_cnt||Number of buffers allocated for storing fragmented packets||Global|
