How do I log into a specific node or cancel a job on a node I'm not logged into?

[StephenHey]

We've had to cancel some background jobs that were running longer than anticipated, but those jobs sometimes get put on a node that we're not logged into.   Depending on the severity, we have the whole team log in until they get the node it's running on (by checking all active transactions).

Is there any way to specify a node to log into as an admin or a way to see all jobs across all nodes?

Hello Stephen ,

Yes you can login into the specific node via setting "BIGipServerpool_InstanceName" Cookies value into ur browser.

To find out the node where that job is running check claimed by field in triggers.

This thread is a little old, but this question still comes up a lot. Technical not supported but very useful and will save you a call to support.

This python script will print a list of node names and their BIGipServerpool_InstanceName values for your instance. I like to use the EditThisCookie Chrome plugin, but there are others.

Hope this is useful.

Thanks, Brandon
