Because we use systemd for most of our service management, these stdout/stderr streams are generally piped into systemd-journald which handles the local machine logs. With its RateLimitBurst and RateLimitInterval configurations, this gives us a simple knob to control the output of any given service on a machine. This has given our logging pipeline the colloquial name of the “journal pipeline”, however as we will see, our pipeline has expanded far beyond just journald logs.
