isEntityMxBeanStatsEnabled

public static boolean isEntityMxBeanStatsEnabled(Entity entity)

connectMXBeanSensors

@Nullable
public static JmxFeed connectMXBeanSensors(Entity entity)

connectJavaAppServerPolicies(Entity, Duration), getMxBeanSensorsBuilder(Entity)

connectMXBeanSensors

@Nullable
public static JmxFeed connectMXBeanSensors(Entity entity,
                                                     long jmxPollPeriodMs)

connectMXBeanSensors

@Nullable
public static JmxFeed connectMXBeanSensors(Entity 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(Entity entity)

connectJavaAppServerPolicies

public static void connectJavaAppServerPolicies(Entity entity,
                                                Duration windowPeriod)

getMxBeanSensorsBuilder

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

Parameters:

entity - The entity at which to poll

Returns:

A JmxFeed.Builder configured to poll entity every ten seconds

See Also:

getMxBeanSensorsBuilder(Entity, Duration)

getMxBeanSensorsBuilder

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

See Also:

getMxBeanSensorsBuilder(Entity, Duration)

getMxBeanSensorsBuilder

@Nonnull
public static JmxFeed.Builder getMxBeanSensorsBuilder(Entity 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.

Use connectMXBeanSensors(Entity, Duration) to create and build in one step.

compositeDataToMemoryUsage

public static <any> compositeDataToMemoryUsage()

init

public static void init()
