Configures the rate limiting interval that is applied to all messages generated on the system. This rate limiting is applied per-service, so that two services which log do not interfere with each other's limit. The value may be specified in the following units: s, min, h, ms, us. To turn off any kind of rate limiting, set either value to 0.
See services.journald.rateLimitBurst for important considerations when setting this value.
