Specified by:

addHarvestListener in interface HarvestService

Parameters:

listener -

removeHarvestListener

public void removeHarvestListener(HarvestListener listener)

Remove a listener.

Specified by:

removeHarvestListener in interface HarvestService

Parameters:

listener -

doStop

protected void doStop()

Specified by:

doStop in class AbstractService

getInitialDelay

public long getInitialDelay()

Get the initial delay in milliseconds.

Tests can override.

setInitialDelayMillis

public void setInitialDelayMillis(long millis)

Override the initial delay.

Parameters:

millis - number of milliseconds to wait

getReportingPeriod

public long getReportingPeriod()

Get the reporting period in milliseconds.

Tests can override.

getMinHarvestInterval

public long getMinHarvestInterval()

Get the minimum harvest interval in nanoseconds.

getEventDataHarvestLimits

public java.util.Map<java.lang.String,java.lang.Object> getEventDataHarvestLimits()

Description copied from interface: HarvestService

Returns the object structure that will be marshaled to JSON for `event_harvest_config` that will get sent up on connect. This JSON will allow for faster event harvesting by returning what the local max_samples_stored value is for each event type.

Specified by:

getEventDataHarvestLimits in interface HarvestService

Returns:

map of event data types to local max samples stored
