Hi , Currently the statistics generated for the bpmn-explorer is generated using jaggery. When the work load is high, the bpmn-explorer takes a longer time to generate these statistics which causes performance issues.
As a solution I am working a new stats REST api to generate these statistics at the back-end. This reduces the work load and thereby solves the performance issues caused during peak times (when the workload is at its maximum). After taking in data about the bpmn processes, tasks and users involved, the api processes these data into meaningful statistics.These statistics generated is used in the bpmn-explorer reporting dashboard to generate the statistical graphs. The statistics generated includes: 1) Average time duration for all completed processes. The user has the option to either view all completed processes or the top 10 processes which finished within a short time duration or the top 10 processes which took a long time duration to finish. 2) Average time duration of tasks of a completed process. The user can select the completed process from the combo box and view the average time duration. 3) User and the no. of tasks he/she has completed upto now. 4) Average time taken by each user to complete the tasks assigned to him/her. 5) Task demand variation over time i.e. no. of tasks started and no. of tasks completed in each month. This is useful for resource allocation purposes. 6) Process demand variation over time i.e. no. of processes started and no. of processes completed in each month regardless of a specific user. This is useful for resource allocation purposes. 7) User Performance i.e. Task demand variation of users separately over time i.e. no. of tasks started and no. of tasks completed in each month. This is useful for resource allocation purposes. I have attached the class diagram of the REST api. The new stats REST api will be integrated with the existing bpmn REST api. Appreciate any suggestions and comments.
