---++ Message Format

The message format complies to the [[https://twiki.cern.ch/twiki/bin/view/LCG/GridMonitoringProbeSpecification][GridMonitoringProbeSpecification]]. Additional the key-value pair =testName= has always to be present:

<verbatim>testName:<name of the test></verbatim>

Besides there are a couple of common key-value pairs. Most of them will be created automatically:

| *key* | *auto* | *description* | *format* | *example* |
| testId | x | Unique id for each test| 32 hex | 7dd4984b03115b34f7993439055f622f |
| testVersion | - | Version of the test | Major.Minor | 1.0 |
| hostname | x | Host name of the WN | URI | lxbra2108.cern.ch | 
| hostid | x | Unique  id for each host | 32 hex | d965877f592d3fdf85d43a28e9dc8380 |
| pyamqId | x | A unique id for each execution of the client | 32 hex | 30ff8d0689a5b23b0024bcf9746ceeb7 |
| pyamqEncrypt | - | States whether a test was/will be encrypted | 0 or 1 | 1 |
| pyamqSubtopic | - | Adds a subtopic to the default destination | \w+(\.\w+)* | site.MySite |
| executionFile | - | File name which was/will be executed | file name | system_os |
| executionArguments | - | Arguments which will be passed to the execution file | arg1 arg2 ... | arg1 |
| executionCommand | x | The command which was executed to get the test results | command | /path/to/test/system_os arg1 |
| executionStarttime | x | Start time of a test | Timestamp | 1234972037.6445301 |
| executionEndtime | x | End time of a test | Timestamp | 1234972037.650563 |
| executionTime | x | Difference between start and end time | Float | 0.0060329437255859375 |
| summary | - | A short summary of the test used by the servers =WebAdmin= | Short String | ok |

 
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.:

<verbatim>
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
</verbatim>

---++ 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%)
