Events in sequentiell / parallel on all host on group

[kash1983]

Hello,
i have an configured an event which works on my xyops main (docker), then i configured two server or an group of servers with xyops-sat (docker) to run the event on.
but even if i run the event it will run only on one of these server group, not at all at the samt time or slightly delayed.
i saw that i can set an algorithm "algo: random" or "algo: roundrobin", i think there should be something like parallel and sequentiell.
or i am dogin something wrong?

help would be really appreciated ;-)

Thanks.

Hi there! So sorry for the confusion. What you are looking for is called a Multiplex Controller which needs to run inside of a Workflow.

The basic idea is that you trigger your workflow based on a schedule (or manually triggered), and wire up the multiplex controller first. Then, wire your event or job to the right side of the multiplex controller, and target it at your group of servers:

This will run the event in parallel across all the servers in the target group.

If you want to adjust concurrency and run the jobs in series or limited parallel, attach a Max Concurrent Jobs and Max Queue Limit to the bottom of the event node like this:

This configuration would run up to 5 multiplexed jobs in parallel, allowing for up to 100 to be queued.

You can also adjust the multiplex "stagger" (delay between launches) when you create or edit the multiplex controller node itself:

Hope this helps!

Do you mind explaining the difference between adding those limiters and the actual limit settings when editing a workflow?

EDIT:

I got it. The workflow limits apply to the full workflow while the limits you mentioned can apply to single events inside the workflow I guess.

ok, i thought i can set events for simple things "cronjob like", like in cronicle before.
and i thought the workflow part is for special or complex stuff.
i dont know current if it is nice to create a workflow for all such simple things.

but thanks for fast reply & help!

I'm so sorry that the feature has changed since Cronicle. It made a lot more sense to implement it as a workflow automation in xyOps.

That being said, if you have an existing Cronicle setup, you can migrate everything over, and it automatically converts all your multiplex events to workflows for you:

Instructions here: https://docs.xyops.io/#Docs/cronicle

Hope this helps!
