TsConnectionStats

Transport-level stats for a connection-less TS input (udpTs / tcpTs). These inputs have no per-connection identity and no SRT-style loss/RTT stats, so the health event carries the media health plus this minimal packet-gap signal.

Field

Type

Repeated

Description

received_packets

int64

Packets received over the sample window (UDP datagrams; for TCP, read chunks).

ms_since_last_packet

int64

Milliseconds since the last packet/read arrived — the transport-level gap. Distinct from StreamHealth.last_media_age_ms, which times the last decoded frame: this fires even when decoding has stopped emitting frames.

seamless

SeamlessProtectionStats

Set only for an ST 2022-7 protected input. The merge happens as packets are received, so there is no node downstream whose throughput would reveal it: this is the only view of whether protection is protecting anything.

rist

RistConnectionStats

Set only for a RIST input: librist’s flow statistics, the only view of how hard retransmission is working (the TS packet counts above see only what came OUT of recovery).

sender

UdpSender

udpTs: the sender the input is taking its stream from (address and port), once one has been admitted. Under the default sender policy (lock to the first) this is the holder of the input until it goes idle or is kicked.

dropped_senders

DroppedSender

✅

udpTs: senders refused, each with how many of its datagrams were dropped and when it was first and last heard from: a second encoder pushing to the port while sender holds the input, or a kicked sender that has not stopped. Listed on every health sample for as long as it keeps sending, and for 30 s after it stops.

errors

TsErrorCounts

ETR 101 290 occurrences over this sample from the input’s TS decoders (udpTs, tcpTs, rist), by kind, with the TS packets seen: the field set of UdpTsPcapProbeStats, per sample rather than running. Counted whether or not etr290 notifications are on. CC errors per second drive the transport_errors health reason.

InputConnectionHealth

Periodic per-connection health for an input connection: measurements only.
