tls

The tls domain includes metrics about the status and configuration of TLS (SSL).

Industry best practice is to always use TLS with MySQL. This domain reports a single derived metric, enabled, that should be monitored to ensure that every MySQL instance has TLS enabled.

True (1) if have_ssl = YES, else false (0). Metrics sinks that don’t support bool report this metric as a gauge.

have_ssl is deprecated as of MySQL 8.0.26. This domain does not currently support the tls_channel_status table but there is an open issue to fix this.
