class patroni.watchdog.Watchdog(config: Config)

Bases: object

Facade to dynamically manage watchdog implementations and handle config changes.

When activation fails underlying implementation will be switched to a Null implementation. To avoid log spam activation will only be retried when watchdog configuration is changed.

_activate() → bool

_disable() → None

_set_timeout() → int | None
