Queue Statistics

Queues are very useful when wanting to offload tasks to background processes. However it can be difficult to get an overview of how they are running. How long does it take before an item is processed? Are the resources allocated to processing items sufficient compared to how many items are generated?

Queue statistics tries to solve this problem by collecting and displaying
statistics about queues used on a Drupal site.

Currently supported statistics include:

• Number of items in queue
• Processing time per item
• Time spent in queue per item
• Processing rate per queue
• Estimated time before all current items are processed

Other modules can extend the module by implementing their own statistic as plugins.
