Context properties
Context properties are user defined key/value pairs which can be associated to a transaction. The standard defines up to twenty context properties per transaction measurement. During registration of transactions the context properties have to be named. Therefore the MyARM-Manager knows for each selected transaction the defined context property names. As shown in "Context property menu" a menu is provided to enable or disables with appropriate context property filter widget. A check mark indicates that the appropriate filter is active and the user can input filter data.
"Context property
menu" shows all context property names of the
HTTP transaction of the apache web-server.
"Context property
filter widgets" shows the active and visible filter
widgets with user input. Each context property filter widget uses
the
string type widget .
