The Mail Queue page is useful to monitor the internal status of the queue and to adjust some parameters.
| Attribute | Description | |||||
|---|---|---|---|---|---|---|
| Total Queued | Total number of email actions queued | |||||
| Total Completed | Total number of email actions completed | |||||
| Currently on Queue | Total number of email actions queued for processing. If you experience that hundreds or thousands of items are waiting on the queue as an average, consider increasing the number of worker threads. | |||||
| Active Worker Threads | Current number of active worker threads processing the email actions. | |||||
| Average Time in Queue (ms) | Average time of the last 100 email actions spent on the queue. Time metric exludes the default queue delay. | |||||
| Maximum Worker Threads | Maximum number of worker threads to process the email actions. Number may vary from 0 to 64.
| |||||
| Maximum number of items waiting on the queue | This is the maximum number of items on the mail queue. Although the items on the queue are small (less than 10Kbyte each), the more items are waiting on the queue (as per the Currently on Queue value above), the more memory is allocated. Theoretically this may lead to Out Of Memory errors putting the system stability at risk. Therefore a hard limitation is introduced to prevent this. Even the largest Jira instances have normally not more than a few hundred items on the queue as an average. If you experience this constantly, consider increasing the number of worker threads. |
