Method Detail

requestStart

public void requestStart(RequestType requestType)

Description copied from interface: Agent

This method is called by a request processor thread, dispatched by the container to process a new request on behalf of a client, before any request processing activity begins. Allowed request types are: 1. Remote HTTP Web request. 2. Remote EJB request. 3. MDB request. 4. Timer EJB. Upon being called, this method allocates a unique request id, and associates it with the thread local state.

Specified by:

requestStart in interface Agent

Parameters:

requestType - Type of the request.

addRequestInfo

public void addRequestInfo(RequestInfo requestInfo,
                           String value)

Description copied from interface: Agent

This method may be called by the container during request dispatch, to add request information such as caller IP address, and remote user name. This method is not required to be called by the container. This method may be called many times by the container, but only before startTime is called.

Specified by:

addRequestInfo in interface Agent

requestEnd

public void requestEnd()

Description copied from interface: Agent

This method is called by a request processor thread, after completion of request processing. Upon being called, this method releases the thread local state.

Specified by:

requestEnd in interface Agent

startTime

public void startTime(ContainerTypeOrApplicationType type)

Description copied from interface: Agent

This method is called by a request processor thread, when the thread of execution transitions into the container code. That is, this method is called from a method preInvoke point, before the container begins method call setup activity.

Specified by:

startTime in interface Agent

Parameters:

type - Describes the type of the container or application.

endTime

public void endTime()

Description copied from interface: Agent

This method is called by a request processor thread, when the thread of execution transitions out of the container code. That is, this method is called from a method postInvoke point, after the container has completed all method call related cleanup activity.

Specified by:

endTime in interface Agent

ejbMethodStart

public void ejbMethodStart(CallFlowInfo info)

Description copied from interface: Agent

This method is called by a request processor thread, before invoking a business method on a target EJB. This trap point must be called after the transaction and security context for the invocation has been established. This trap point collects information about the target EJB invocation.

Specified by:

ejbMethodStart in interface Agent

Parameters:

info - This object encapsulates information such as method name, component type, application name, module name, component name, transaction id, and security id.

ejbMethodEnd

public void ejbMethodEnd(CallFlowInfo info)

Description copied from interface: Agent

This method is called by a request processor thread, after invoking a business method on a target EJB. This trap point gathers information about the outcome of the invocation such as exception, if any.

Specified by:

ejbMethodEnd in interface Agent

Parameters:

info - This object encapsulates information about the outcome of the invocation such as exception, if any.

webMethodStart

public void webMethodStart(String methodName,
                           String applicationName,
                           String moduleName,
                           String componentName,
                           ComponentType componentType,
                           String callerPrincipal)

Description copied from interface: Agent

This method is called by a request processor thread, before invoking a target method on a filter or servlet. This trap point must be called after the invocation context for the invocation is established. This trap point collects information such as method name, component name, component type, application name, module name, callerPrincipal.

Specified by:

webMethodStart in interface Agent

webMethodEnd

public void webMethodEnd(Throwable exception)

Description copied from interface: Agent

This method is called by a request processor thread, after invoking a target method on a filter or servlet. This trap point gathers information on the outcome of the invocation such as exception, if any.

Specified by:

webMethodEnd in interface Agent
