Diagnostics Flags

Diagnostics flags let you enable targeted debug logs without turning on verbose logging everywhere. Flags are opt-in and have no effect unless a subsystem checks them.

How it works

  • Flags are strings (case-insensitive).
  • You can enable flags in config or via an env override.
  • Wildcards are supported:
    • telegram.* matches telegram.http
    • * enables all flags

Enable via config

json
{
  "diagnostics": {
    "flags": ["telegram.http"]
  }
}

Multiple flags:

json
{
  "diagnostics": {
    "flags": ["telegram.http", "gateway.*"]
  }
}

Restart the gateway after changing flags.

Env override (one-off)

bash
MAYROS_DIAGNOSTICS=telegram.http,telegram.payload

Disable all flags:

bash
MAYROS_DIAGNOSTICS=0

Where logs go

Flags emit logs into the standard diagnostics log file. By default:

/tmp/mayros/mayros-YYYY-MM-DD.log

If you set logging.file, use that path instead. Logs are JSONL (one JSON object per line). Redaction still applies based on logging.redactSensitive.

Extract logs

Pick the latest log file:

bash
ls -t /tmp/mayros/mayros-*.log | head -n 1

Filter for Telegram HTTP diagnostics:

bash
rg "telegram http error" /tmp/mayros/mayros-*.log

Or tail while reproducing:

bash
tail -f /tmp/mayros/mayros-$(date +%F).log | rg "telegram http error"

For remote gateways, you can also use mayros logs --follow (see /cli/logs).

Notes

  • If logging.level is set higher than warn, these logs may be suppressed. Default info is fine.
  • Flags are safe to leave enabled; they only affect log volume for the specific subsystem.
  • Use /logging to change log destinations, levels, and redaction.
