Completed process: how to visualize and show variables

imbaczek — Thu, 07 Nov 2013 12:26:24 GMT

I've got a process that doesn't have any human tasks. I'd like to see its variables and execution path just as if I was looking at a running process (for debugging and monitoring). Is this possible? Sounds like an obvious use case, I just hope its hidden too well for me to find it. Having the option

Hi imbaczek,

The value in {} bracket is variable value when process execution left the node. It means that process started with x=0, after the first step x= x+1 => x had value 1. User changed x value to 3.

Image displayed is audit trail (only path for this process instance is displayed) . Complete process definition is

to see how it was done see https://github.com/gro-mar/activiti-crystalball/wiki/Optimize-the-process-2

Another good point to start could be https://github.com/gro-mar/activiti-crystalball/blob/master/simulator/src/test/java/org/activiti/crystalball/simulator/GenerateProcessEngineState.java

 
            // audit trail images generator
                AuditTrailProcessDiagramGenerator generator = new AuditTrailProcessDiagramGenerator();
                generator.setHistoryService(historyService);
                generator.setRepositoryService((RepositoryServiceImpl) repositoryService);
                generator.setWriteUpdates(true);

                Map<String, Object> params = new HashMap<String,Object>();
                params.put( AuditTrailProcessDiagramGenerator.PROCESS_INSTANCE_ID, processInstance1.getId());
                
                ImageIO.write( ImageIO.read(generator.generateLayer("png", params))
                                , "png"
                                , new File( TEMP_DIR+"/playback-auditTrail1.png"));
