Sensor specific options
Starts invocation
Applies to Timer sensor
As already mentioned the Invocation Sequence sensor can not be applied directly to sensor assignment. Instead of this you can mark any Timer sensor assignment to start the invocation as well as capturing the timing information. This is done by activating the Starts invocation option in the assignment sensor specific options. It's possible to optionally also set the minimum duration property. This property defines the minimum time an invocation has to consume in order to be saved and transmitted to the server. This helps in reducing the data load from the Agent to the CMR and is a good filter for not so important invocations.
If the starts invocation is active the Options column of the sensor assignment table will display this icon: .
Charting
Applies to Timer and HTTP sensor
With the charting option it is possible to define what data should be considered as the long-term data available for charting in inspectIT User interface. This data is additionally saved to the database, thus even when the CMR is shutdown or buffer is cleared the data will be available via charts. With this approach it is possible to define exactly what methods performance data should be considered as long-term.
The configuration of the charting option is defined in the sensor assignment for Timer and HTTP sensor:
If the charting option is active the Options column of the sensor assignment table will display this icon: 
.
Context capturing
Applies to Timer sensor
Please visit the Context capturing in sensor assignment for more information on context capturing option.
