Healthcheck

There are currently two health checks executed for each API.

• The JVM thread deadlock check verifies that no deadlocks exist in the KairosDB JVM.
• The Datastore query check performs a query on the data store to ensure that the data store is responding.

KairosDB provides REST APIs that show the health of the system.

See HealthCheck
