The agent has to know when to send its measurements to the CMR. For that purpose, sending strategies must be defined. There are two available options:
Sending strategy | Description | Option |
|---|---|---|
Time Strategy | This strategy will cause the agent to send its measurements after a specific interval. This interval can be set by using the option text box. | time in milliseconds |
List Size Strategy | This strategy will cause the agent to send its measurements after a specific size of value objects is reached. The size can be set by using the option text box. | size |
Buffer strategy
The next important aspect to configure is how the agent should handle connection problems when they appear. One could imagine that there is no buffer at all, or a specified size etc. After a connection is reestablished, the buffer will return all the elements it contains and they will be send to the CMR.
Buffer strategy | Description | Options |
|---|---|---|
Simple Buffer | The simplest version of a buffer is apparently no buffer at all. It contains exactly one element. This is useful if old data isn't necessary or maybe the memory of the application is very limited. | none |
Size Buffer | This buffer strategy needs an additional size option to set the size of this buffer. This buffer works as a FILO stack, so last added elements will be sent first (as they are more important), and old ones are thrown away if this buffer is full. | size |

Sensor options part defines all possible general sensor options that can be configured.
String length
All the method-sensor-types and the exception-sensor-type allow specification of the string length option. With this option a user can specify maximum length of Strings values collected by these sensors. What the String values are depend on the concrete sensor used. For example, database related sensors will decrease the size of the SQL statement strings if the length is higher than the specified one. On the other hand, the exception sensor will, for example, decrease the size of the exception stack trace and/or message.
