Renewed Statistics Function

The recently released gUSE/WS-PGRADE portal version 3.5.7’s main feature is the optimization of the statistics function to speed up the loading and to relive the database and the portal in overall.

Since version 3.4.1 gUSE/WS-PGRADE portals are capable to provide a very useful functionality for the users: the collection and visualization of usage statistics or shortly the statistics function. This function is responsible for collecting and storing metrics in the database and for the display of these metrics. The statistics function allows viewing metrics in four tabs – portal, DCI, user, and workflow –, on seven levels – portal, user, DCI, resource, concrete workflow, workflow instance and abstract job. This is accomplished by allowing users to navigate to different pages to see the level of statistics they want. This solution is helpful for administrator in resource settings (mainly from portal and DCI statistics) for users in middleware, resource selecting and in job execution time estimation (mainly from user and workflow statistics).

The gUSE Development Team decided that the gUSE system’s load caused by the statistics function should be reduced with a system background development. Thus, from version 3.5.7 the fast statistical data processing and providing mechanism loads the gUSE database at lower level than earlier and exploits the resources more effectively than in the previous gUSE versions.
