Output Format

Stellar Relay sends NDJSON over a raw TCP connection. Each record is:

one UTF-8 JSON object
terminated by LF (\n)
sent as one logical line

Example framing:

{"stellar_record_type":"alert",...}\n
{"stellar_record_type":"case",...}\n

The receiver must preserve line boundaries and parse each line as an independent JSON object.

The historical CLI names --alert-syslog-* and --case-syslog-* do not mean the payload is RFC 5424 syslog.

Alert and Case can use separate destinations or the same destination. When sharing a destination, distinguish record types using JSON fields such as stellar_record_type.

Receiver checklist

TCP listener is reachable from the relay host
listener accepts newline-delimited UTF-8 data
parser treats each line as JSON
firewall allows the configured destination port
receiver capacity is sufficient for retry/backfill bursts
