• connectMXBeanSensors

  @Nullable
  public static JmxFeed connectMXBeanSensors(EntityLocal entity,
                                      Duration jmxPollPeriod)

  Parameters:

  entity - The entity at which to poll

  jmxPollPeriod - How often to poll

  Returns:

  A JmxFeed configured to poll the given entity at the given period, or null if the entity is not configured for MXBEAN_STATS

  See Also:

  UsesJavaMXBeans.MXBEAN_STATS_ENABLED

• connectJavaAppServerPolicies

  public static void connectJavaAppServerPolicies(EntityLocal entity)

• connectJavaAppServerPolicies

  public static void connectJavaAppServerPolicies(EntityLocal entity,
                                  Duration windowPeriod)

• getMxBeanSensorsBuilder

  @Nonnull
  public static JmxFeed.Builder getMxBeanSensorsBuilder(EntityLocal entity)

  Parameters:

  entity - The entity at which to poll

  Returns:

  A JmxFeed.Builder configured to poll entity every ten seconds

  See Also:

  getMxBeanSensorsBuilder(EntityLocal, Duration)

• getMxBeanSensorsBuilder

  @Nonnull
  public static JmxFeed.Builder getMxBeanSensorsBuilder(EntityLocal entity,
                                                long jmxPollPeriod)

  See Also:

  getMxBeanSensorsBuilder(EntityLocal, Duration)

• getMxBeanSensorsBuilder

  @Nonnull
  public static JmxFeed.Builder getMxBeanSensorsBuilder(EntityLocal entity,
                                                Duration jmxPollPeriod)

  Parameters:

  entity - The entity at which to poll

  jmxPollPeriod - How often to poll

  Returns:

  A JmxFeed.Builder configured to poll many interesting MXBeans at the given entity and to repeat according to the given poll period.

  If an entity does not have MXBean stats enabled (i.e. UsesJavaMXBeans.MXBEAN_STATS_ENABLED is configured to false) then returns a builder configured with entity and duration but no polls.
