+Job execution is monitored by reading a log file of the job. A job consists of a number of steps which consists of a number of operations ([http://www.molgenis.org/wiki/ComputeStartDataModel MCF Data Model]). A step of the job can be started when all operations of a previous step are finished. Operations in a step can be executed in parallel. Every operation writes to a job log file. Monitoring is implemented by reading job log files. Monitoring is called from [http://www.molgenis.org/svn/sandbox/molgenis_processing/3.3.galaxy/ScriptbasedComputePlatform/src/scriptserver/PipelineThread.java PipelineThread] after step is submitted for execution:
+
+{{{
+int numberOfSteps = pipeline.getNumberOfSteps();
+
+for (int i = 0; i < numberOfSteps; i++)
+{
+        Step step = pipeline.getStep(i);
+
+    //here, step is submitted for execution
+    
+    ...
+    
+    monitor.setStep(step);
+
+        while (!monitor.isNotFinishedStep())
+    {
+        monitor.checkStepStatus();
+
+        try
+        {
+                Thread.sleep(5000);
+        }
+                ...
+        //continue to a next step       
+        ...
