    • CONTAINER_HEALTH_THRESHOLD_PERCENT

      public static final String CONTAINER_HEALTH_THRESHOLD_PERCENT
      The container health threshold percent when explicitly set for a specific component or globally for all components, will schedule a health check monitor to periodically check for the percentage of healthy containers. It runs the check at a specified/default poll frequency. It allows a component to be below the health threshold for a specified/default window after which it considers the service to be unhealthy and triggers a service stop. When health threshold percent is enabled, CONTAINER_FAILURE_THRESHOLD is ignored.
      See Also:

    • CONTAINER_HEALTH_THRESHOLD_POLL_FREQUENCY_SEC

      public static final String CONTAINER_HEALTH_THRESHOLD_POLL_FREQUENCY_SEC
      Health check monitor poll frequency. It is an advanced setting and does not need to be set unless the service owner understands the implication and does not want the default.
      See Also:

    • CONTAINER_HEALTH_THRESHOLD_WINDOW_SEC

      public static final String CONTAINER_HEALTH_THRESHOLD_WINDOW_SEC
      The amount of time the health check monitor allows a specific component to be below the health threshold after which it considers the service to be unhealthy.
      See Also:

    • CONTAINER_HEALTH_THRESHOLD_INIT_DELAY_SEC

      public static final String CONTAINER_HEALTH_THRESHOLD_INIT_DELAY_SEC
      The amount of initial time the health check monitor waits before the first check kicks in. It gives a lead time for the service containers to come up for the first time.
      See Also:

    • CONTAINER_HEALTH_THRESHOLD_PERCENT_DISABLED

      public static final int CONTAINER_HEALTH_THRESHOLD_PERCENT_DISABLED
      By default the health threshold percent does not come into play until it is explicitly set in resource config for a specific component or globally for all components. -1 signifies disabled.
