Worker Node Configuration Database

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 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
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.:

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



  • 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%)
