Watchdog uses default values for all thresholds defined in `docker-compose.yml`.
|
|
|
|
The default values will work for most setups.
|
|
Example:
|
|
```
|
|
- NGINX_THRESHOLD=${NGINX_THRESHOLD:-5}
|
|
- UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}
|
|
- REDIS_THRESHOLD=${REDIS_THRESHOLD:-5}
|
|
- MYSQL_THRESHOLD=${MYSQL_THRESHOLD:-5}
|
|
- MYSQL_REPLICATION_THRESHOLD=${MYSQL_REPLICATION_THRESHOLD:-1}
|
|
- SOGO_THRESHOLD=${SOGO_THRESHOLD:-3}
|
|
- POSTFIX_THRESHOLD=${POSTFIX_THRESHOLD:-8}
|
|
- CLAMD_THRESHOLD=${CLAMD_THRESHOLD:-15}
|
|
- DOVECOT_THRESHOLD=${DOVECOT_THRESHOLD:-12}
|
|
- DOVECOT_REPL_THRESHOLD=${DOVECOT_REPL_THRESHOLD:-20}
|
|
- PHPFPM_THRESHOLD=${PHPFPM_THRESHOLD:-5}
|
|
- RATELIMIT_THRESHOLD=${RATELIMIT_THRESHOLD:-1}
|
|
- FAIL2BAN_THRESHOLD=${FAIL2BAN_THRESHOLD:-1}
|
|
- ACME_THRESHOLD=${ACME_THRESHOLD:-1}
|
|
- RSPAMD_THRESHOLD=${RSPAMD_THRESHOLD:-5}
|
|
- OLEFY_THRESHOLD=${OLEFY_THRESHOLD:-5}
|
|
- MAILQ_THRESHOLD=${MAILQ_THRESHOLD:-20}
|
|
- MAILQ_CRIT=${MAILQ_CRIT:-30}
|
|
```
|
|
|
|
To adjust them just add necessary threshold variables (e.g. `MAILQ_THRESHOLD=10`) to `mailcow.conf` and run `docker-compose up -d`.
