Message Format
The message format complies to the
GridMonitoringProbeSpecification. Additional the key-value pair
testName has always to be present:
testName:<name of the test>
Besides there are a couple of common key-value pairs. Most of them will created automatically:

The key
detailsdata is a special key. It must, if it exists, be the final line in the message. It usually contains log messages of the test, e.g.:
detailsdata:java version could not be gathered
java not found, try JAVA_HOME: /usr/java/jdk1.5.0_16
/usr/java/jdk1.5.0_16/bin/java: No such file or directory
exitcode:127
Tests
Scheduling
- Interval Scheduling
- Run tests after a certain timeout is exeeded. (e.g 1 day)
- Probability Scheduling
- Run tests randomly with a certain probability. (e.g 0.2 means 20%)
