Method Detail

reportEvent

Action reportEvent(java.lang.String eventName)

Reports an event with a specified name (but without any value).

If given eventName is null or an empty String then no event is reported to the system.

Parameters:

eventName - name of the event

Returns:

this Action (for usage as fluent API)

reportValue

Action reportValue(java.lang.String valueName,
                   int value)

Reports an int value with a specified name.

If given valueName is null or an empty String then no event is reported to the system.

Parameters:

valueName - name of this value

value - value itself

Returns:

this Action (for usage as fluent API)

reportValue

Action reportValue(java.lang.String valueName,
                   long value)

Reports a long value with a specified name.

If given valueName is null or an empty String then no event is reported to the system.

Parameters:

valueName - name of this value

value - value itself

Returns:

this Action (for usage as fluent API)

reportValue

Action reportValue(java.lang.String valueName,
                   double value)

Reports a double value with a specified name.

If given valueName is null or an empty String then no event is reported to the system.

Parameters:

valueName - name of this value

value - value itself

Returns:

this Action (for usage as fluent API)

reportValue

Action reportValue(java.lang.String valueName,
                   java.lang.String value)

Reports a String value with a specified name.

If given valueName is null or an empty String then no event is reported to the system.

Parameters:

valueName - name of this value

value - value itself The value can be null or an empty String.

Returns:

this Action (for usage as fluent API)

reportError

Action reportError(java.lang.String errorName,
                   int errorCode)

Reports an error with a specified name and error code.

If given errorName is null or an empty String then no event is reported to the system.

Parameters:

errorName - name of this error

errorCode - numeric error code of this error

Returns:

this Action (for usage as fluent API)

reportError

Action reportError(java.lang.String errorName,
                   java.lang.String causeName,
                   java.lang.String causeDescription,
                   java.lang.String causeStackTrace)

Reports an error with a specified name and fields describing the cause of this error.

If given errorName is null or an empty string then no event is reported to the system. If the causeDescription is longer than 1000 characters, it is truncated to this value. If the causeStackTrace is longer than 128.000 characters, it is truncated according to the last line break.

Parameters:

errorName - name of this error

causeName - name describing the cause of the error. E.g. the class name of a caught exception.

causeDescription - description what caused the error E.g. Throwable.getMessage() of a caught exception.

causeStackTrace - stack trace of the error E.g. the Throwable stack trace

Returns:

this Action (for usage as fluent API)

reportError

Action reportError(java.lang.String errorName,
                   java.lang.Throwable throwable)

Reports an error with a specified name and a Throwable.

If given errorName is null or an empty string then no event is reported to the system.

Parameters:

errorName - name of this error

throwable - Throwable causing this error

Returns:

this Action (for usage as fluent API)

traceWebRequest

WebRequestTracer traceWebRequest(java.net.URLConnection connection)

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.

If given connection is null then no event is reported to the system.

Parameters:

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

Returns:

a WebRequestTracer which allows adding timing information

traceWebRequest

WebRequestTracer traceWebRequest(java.lang.String url)

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.

If given url is null or an empty string then no event is reported to the system.

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

leaveAction

Action leaveAction()

Leaves this Action.

Returns:

the parent Action, or null if there is no parent Action

cancelAction

Action cancelAction()

Cancels this Action.

Canceling an action is similar to leaving an action, except that the data and all unfinished child objects are discarded instead of being sent.

Returns:

the parent Action, or null if there is no parent Action

getDurationInMilliseconds

long getDurationInMilliseconds()

Get the action's duration in milliseconds.

The duration of an Action is equal to the current timestamp - start timestamp, if the action is still open, or end timestamp - start timestamp if leaveAction() or cancelAction() was already called.

Returns:

The duration of this Action.
