Method Detail

all

public List<ProcessingStatusDto> all()

Rerturns all existing processing status entries from the database.

Returns:

a list of all processing status entries

get

public Optional<ProcessingStatusDto> get()

Returns the processing status entry for the calling node.

Returns:

the processing status entry or an empty optional if none exists

earliestPostIndexingTimestamp

public Optional<org.joda.time.DateTime> earliestPostIndexingTimestamp()

Returns the earliest post-indexing receive timestamp of all active Graylog nodes in the cluster. This can be used to find out if a certain timerange is already searchable in Elasticsearch.

Beware: This only takes the message receive time into account. It doesn't help when log sources send their messages late.

Returns:

earliest post-indexing timestamp or empty optional if no processing status entries exist

save

public ProcessingStatusDto save(ProcessingStatusRecorder processingStatusRecorder)

Create or update (upsert) a processing status entry for the given ProcessingStatusRecorder using the caller's node ID.

Parameters:

processingStatusRecorder - the processing recorder object to create/update

Returns:

the created/updated entry
