Liveness Health Check
--liveness-check option is used, Chronicle enables liveness
depth charge checks to ensure system availability. It starts a background
task that periodically executes a transaction to Chronicle's
System Namespace. At each interval,
the depth charge operation is executed and timed. If the transaction is
successfully committed, the elapsed time of the round trip is calculated
and made available as a histogram metric.
The liveness check task installs a Prometheus
exporter to record metrics. If the transaction is successfully committed,
the elapsed time of the round trip is calculated and recorded as a
histogram metric in the Prometheus exporter. The collected data can be
scraped from the exposed endpoint for analysis and monitoring purposes at
127.0.0.1:9000/metrics or simply
