This is the interface to the config services. The implementation of this service should act as the manager between incoming tracepoint configs and instrumentation. To help reduce the time spent in the instrumentor.

Method Summary

Modifier and Type	Method	Description
void	configUpdate(long tsNano, String hash, Collection<TracePointConfig> tracepoints)	This indicates that the config from the servers has changed, and we should inform the instrumentation services.
String	currentHash()	Get the hash of the config last used to update the config.
Collection<TracePointConfig>	loadTracepointConfigs(Collection<String> tracepointId)	Load the full configs for the given tracepoints ids.
void	noChange(long tsNano)	Called when there is no change to the config so just update last seen.

Method Detail

noChange

void noChange(long tsNano)

Called when there is no change to the config so just update last seen.

Parameters:

tsNano - the time of the config update

configUpdate

void configUpdate(long tsNano,
                  String hash,
                  Collection<TracePointConfig> tracepoints)

This indicates that the config from the servers has changed, and we should inform the instrumentation services.

Parameters:

tsNano - the time of the update

hash - the new config hash

tracepoints - the new config

currentHash

String currentHash()

Get the hash of the config last used to update the config. This hash should be sent with the calls for new configs, so the server knows what the clients config is and can detect changes.

Returns:

the current hash.

loadTracepointConfigs

Collection<TracePointConfig> loadTracepointConfigs(Collection<String> tracepointId)

Load the full configs for the given tracepoints ids.

Parameters:

tracepointId - the tracepoint ids

Returns:

a collection of all the matched tracepoints
