View Completed Task on Dashboard

[utkarsh19467]

Hi Team,

We are able to see Running, Pending and Scheduled task in a queue using dashboard. Is it possible to enable a option on UI where we can see those task with data which completed the execution.

Note: We can see the graph, but we want to see completed task data on UI as we are able to see the scheduled ones. Please help around this.

Did you mean to add completed tasks section on top navigation bar?

Even each queue has such sections, the problem with completed tasks is it will consume Redis resources and that can lead to OOM. We can add another datastore to store completed tasks if you want.

What all data do you need about completed tasks?

What all data do you need about completed tasks?

Some basic info about the completed task like:

• Data for each Queue
• Data for all those tasks which we successfully consumed by the listeners

Only these basic information are required. Also, are these completed task stored in Redis??. Please let me know.

Completed tasks are stored in Redis for 30 minutes

rqueue/rqueue-core/src/main/java/com/github/sonus21/rqueue/config/RqueueConfig.java

Line 71 in 2fdbbe7

@Value("${rqueue.job.durability.in-terminal-state:1800}")

You can change this to zero if you want in that case it won't store.

Data for each Queue

can you please clarify, what data do you want?

Data for all those tasks which we successfully consumed by the listeners

What/which data should be displayed?

"Completed tasks are stored in Redis for 30 minutes" -> Can you please elaborate in which redis key I can see this completed data.

"What/which data should be displayed?" -> RqueueMessage Data i.e. messageId, enqueued task data. We can see enqueue details when the task is in running or scheduled mode, similarly, can we see for the completed task as well??

Please help with above queries.

There's no specific key they're stored in message metadata, so you need to scan to identify them. We need to add message ids in ZSET and display them, we need to also delete older keys periodically as it can increase the overall memory usage. Will look into this soon.

RqueueMessage Data i.e. messageId, enqueued task data. We can see enqueue details when the task is in running or scheduled mode, similarly, can we see for the completed task as well??

Yes it's possible to display such data see affirmative information.

Can you try version 2.10.0.SNAPSHOT and see if this works for you?
