See [Using `coconut`](./coconut/README.md) for instructions on the O² Control core command line interface.

# Running AliECS in production

The AliECS core runs as a systemd service in the O²/FLP cluster at Point 2.

## Health checks

There is a checker script that polls AliECS for its status (`coconut env list`).

1) The checker script runs via cron (checkAliECScore available in GL) and makes 3 attempts with 10 seconds timeout.
2) All failed attempts are recorded in the aliecs local file /tmp/checkAliECScore.out
3) The ILG message is issued at the third consecutive failure.
