<h1>Thresholds</h1>
<p>Watchdog uses default values for all thresholds defined in <code>docker-compose.yml</code>.</p>
<p>The default values will work for most setups.</p>
<p>Example:</p>

- UNBOUND_THRESHOLD=${UNBOUND_THRESHOLD:-5}
- REDIS_THRESHOLD=${REDIS_THRESHOLD:-5}

- 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}
