Method Detail

getElasticsearchClient

public ElasticsearchClient getElasticsearchClient()

This method gets the elasticsearch client.

Returns:

The elasticsearch client

setElasticsearchClient

public void setElasticsearchClient(ElasticsearchClient client)

This method sets the elasticsearch client.

Parameters:

client - The elasticsearch client

getFragment

public Trace getFragment(String tenantId,
                         String id)

Specified by:

getFragment in interface TraceService

getTrace

public Trace getTrace(String tenantId,
                      String id)

Specified by:

getTrace in interface TraceService

processConnectedFragment

protected void processConnectedFragment(String tenantId,
                                        Trace root,
                                        Trace fragment,
                                        Producer producer)

This method aggregates enhances the root trace, representing the complete end to end instance view, with the details available from a linked trace fragment that should be attached to the supplied Producer node. If the producer node is null then don't merge (as fragment is root) and just recursively process the fragment to identify additional linked fragments.

Parameters:

tenantId - The tenant id

root - The root trace

fragment - The fragment to be processed

producer - The producer node, or null if processing the top level fragment

searchFragments

public List<Trace> searchFragments(String tenantId,
                                   Criteria criteria)

Specified by:

searchFragments in interface TraceService

internalQuery

protected static List<Trace> internalQuery(ElasticsearchClient client,
                                           String tenantId,
                                           Criteria criteria)

This method performs the query.

Parameters:

client - The elasticsearch client

tenantId - The tenant id

criteria - The criteria

Returns:

The list of traces

storeFragments

public void storeFragments(String tenantId,
                           List<Trace> traces)
                    throws StoreException

Specified by:

storeFragments in interface TraceService

Throws:

StoreException

clear

public void clear(String tenantId)

Specified by:

clear in interface TraceService
