Method Detail

noChange

public void noChange(long tsNano)

Description copied from interface: ITracepointConfig

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

Specified by:

noChange in interface ITracepointConfig

Parameters:

tsNano - the time of the config update

configUpdate

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

Description copied from interface: ITracepointConfig

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

Specified by:

configUpdate in interface ITracepointConfig

Parameters:

tsNano - the time of the update

hash - the new config hash

tracepoints - the new config

currentHash

public String currentHash()

Description copied from interface: ITracepointConfig

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.

Specified by:

currentHash in interface ITracepointConfig

Returns:

the current hash.

loadTracepointConfigs

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

Description copied from interface: ITracepointConfig

Load the full configs for the given tracepoints ids.

Specified by:

loadTracepointConfigs in interface ITracepointConfig

Parameters:

tracepointId - the tracepoint ids

Returns:

a collection of all the matched tracepoints

addCustom

public TracePointConfig addCustom(String path,
                                  int line,
                                  Map<String,String> args,
                                  Collection<String> watches,
                                  Collection<MetricDefinition> metrics)

Add a new tracepoint via code api.

Parameters:

path - the tracepoint path

line - the tracepoint line

args - the tracepoint args

watches - the tracepoint watches

metrics - the list of metric expressions

Returns:

the new tracepoint config

IDeep.registerTracepoint(String, int)

removeCustom

public void removeCustom(TracePointConfig tracePointConfig)

Remove a custom tracepoint.

Parameters:

tracePointConfig - the tracepoint to remove
