The dashboard is a central place to view the overall progress of a single workflow. Every dashboard contains a set of user-selected widgets. It should be possible to move all widgets within the dashboard or remove them from it.

The following picture shows the sketch of the dashboard. 

The widgets contain the following information:

1. “Workflow Resources” widget. It contains:

• workflow name;

• workflow start time;

• time left (finish time can be shown as a tooltip);

• percentage of the workflow running progress;

• amount of used memory;

• percentage of CPU usage;

1. “Output Files” widget. It contains a table with the information about all created output files. The table columns are:

• clickable file name;

• the name of the workflow element that has produced the file;

• is it a temporary or final file;

• file status: is written, ready, deleted (for temporary files); 

1. “Common Statistics” widget. It contains a table with common statistic for each workflow element in the scheme. The table columns are:

• name of the workflow element;

• time of the workflow element execution;

• the number of messages that has been retrieved; 

1. User-defined widgets. When a user creates a workflow he/she can choose what parameters he/she wants to watch in runtime. This data will be shown in dashboard widgets and will be updated dynamically during the workflow running process. The data is represented by charts.
