All Implemented Interfaces:

Session, ServerConfigurationUpdateCallback, OpenKitObject, java.io.Closeable, java.lang.AutoCloseable

public class SessionProxyImpl
extends OpenKitComposite
implements Session, ServerConfigurationUpdateCallback

Implements a surrogate for a Session to perform session splitting after:

• a configured number of events
• after a configured idle timeout
• after a configured maximum session duration

Method Summary

Modifier and Type	Method and Description
void	close()
void	end() Ends this Session and marks it as ready for immediate sending.
RootAction	enterAction(java.lang.String actionName) Enters an Action with a specified name in this Session.
void	identifyUser(java.lang.String userTag) Tags a session with the provided userTag.
boolean	isFinished() Indicates whether this session proxy was finished or is still open.
void	onServerConfigurationUpdate(ServerConfiguration serverConfig) Called when a server configuration is updated.
void	reportCrash(java.lang.String errorName, java.lang.String reason, java.lang.String stacktrace) Reports a crash with a specified error name, crash reason and a stacktrace.
long	splitSessionByTime() Will end the current active session and start a new one but only if the following conditions are met: this session proxy is not finished. session splitting by idle timeout is enabled and the current session was idle for longer than the configured timeout.

Method Detail

enterAction

public RootAction enterAction(java.lang.String actionName)

Description copied from interface: Session

Enters an Action with a specified name in this Session.

If the given actionName is null or an empty string, no reporting will happen on that RootAction.

Specified by:

enterAction in interface Session

Parameters:

actionName - name of the Action

Returns:

Action instance to work with

identifyUser

public void identifyUser(java.lang.String userTag)

Description copied from interface: Session

Tags a session with the provided userTag.

If the given userTag is null or an empty string, this is equivalent to logging off the user.

The last non-empty userTag is re-applied to split sessions. Details are described in https://github.com/Dynatrace/openkit-java/blob/main/docs/internals.md#identify-users-on-split-sessions.

Specified by:

identifyUser in interface Session

Parameters:

userTag - id of the user or null/"" to simulate a log off.

reportCrash

public void reportCrash(java.lang.String errorName,
                        java.lang.String reason,
                        java.lang.String stacktrace)

Description copied from interface: Session

Reports a crash with a specified error name, crash reason and a stacktrace.

If the given errorName is null or an empty string, no crash report will be sent to the server.

Specified by:

reportCrash in interface Session

Parameters:

errorName - name of the error leading to the crash (e.g. Exception class)

reason - reason or description of that error

stacktrace - stacktrace leading to that crash

traceWebRequest

public WebRequestTracer traceWebRequest(java.net.URLConnection connection)

Description copied from interface: Session

Traces a web request - which is provided as a URLConnection - and allows adding timing information to this request. If the web request is continued on a server-side Agent (e.g. Java, .NET, ...) this Session will be correlated to the resulting server-side PurePath.

Specified by:

traceWebRequest in interface Session

Parameters:

connection - the URLConnection of the HTTP request to be tagged and timed

Returns:

a WebRequestTracer which allows adding timing information

traceWebRequest

public WebRequestTracer traceWebRequest(java.lang.String url)

Description copied from interface: Session

Allows tracing and timing of a web request handled by any 3rd party HTTP Client (e.g. Apache, Google, Jetty, ...). In this case the Dynatrace HTTP header (OpenKitConstants.WEBREQUEST_TAG_HEADER) has to be set manually to the tag value of this WebRequestTracer.
If the web request is continued on a server-side Agent (e.g. Java, .NET, ...) this Session will be correlated to the resulting server-side PurePath.

Specified by:

traceWebRequest in interface Session

Parameters:

url - the URL of the web request to be tagged and timed

Returns:

a WebRequestTracer which allows getting the tag value and adding timing information

end

public void end()

Description copied from interface: Session

Ends this Session and marks it as ready for immediate sending.

Specified by:

end in interface Session

isFinished

public boolean isFinished()

Indicates whether this session proxy was finished or is still open.

close

public void close()

Specified by:

close in interface java.io.Closeable

Specified by:

close in interface java.lang.AutoCloseable

splitSessionByTime

public long splitSessionByTime()

Will end the current active session and start a new one but only if the following conditions are met:

• this session proxy is not finished.
• session splitting by idle timeout is enabled and the current session was idle for longer than the configured timeout.
• session splitting by maximum session duration is enabled and the session was open for longer than the maximum configured session duration.

Returns:

the time when the session might be split next. This can either be the time when the maximum session duration is reached or the time when the idle timeout expires. In case this session proxy is finished, -1 is returned.

onServerConfigurationUpdate

public void onServerConfigurationUpdate(ServerConfiguration serverConfig)

Description copied from interface: ServerConfigurationUpdateCallback

Called when a server configuration is updated.

Specified by:

onServerConfigurationUpdate in interface ServerConfigurationUpdateCallback

Parameters:

serverConfig - the updated server configuration.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
