Stacks for single session instead of all MSAgents

[c3rberus]

Hello,

Iceberg supports dumping stacks for all MSagents as per docs...

oemanager stacks - [RO] Obtain stack information for all MSAgents for an ABL App

It would be useful in some cases to get stacks for a single session, being able to pass in something like -Dsessid=[SESSION_ID] and get stacks for a single session instead of all.

The API to do this is exposed via oemanager.war, specifically: /applications/{appName}/agents/{agentID}/sessions/{sessionID}/stacks

Would it be possible to add this feature?

I was about to say, I thought I added the feature recently, and I apparently did. However, it's only used as part of the "Trim Session" functionality to dump the session stack prior to termination. Looks like the front-end would just need to have the input added so it can be passed through. I can add this request to our backlog to prioritize.

[c3rberus]

Yeah, it's great that it's there when trim is called, but sometimes we just want to be able to stack a single running session a few times to see what's going on and where in the call stack things are at :) Thanks for adding this to the backlog, I will keep an eye out and test it out when it becomes available.

Hi Dustin, any update on this one?

[DustinGrau-PSC]

Unfortunately no movement yet due to higher priorities since the start of the year. It's still logged and waiting for action.

Good news, I was able to take a look at the scope of the change which was small enough to take on for a quick fix. I'm working to get the changes incorporated into the main branch though they are available here if you wish to preview: https://github.com/progress/iceberg/tree/develop-march24

If that branch is gone by the time you have a chance to look, then take that as a sign the enhancement was merged.

UPDATE: The changes have now been merged.

Hi Dustin,

This is great news, I tried the latest merge, and it looks like the utils.zip has the dos break lines ^M in the file, this breaks functionality.

Found iceberg repository, continuing.

I can work around this, but just as a FYI.

[DustinGrau-PSC]

That's interesting as I did not directly modify the shell scripts as part of the work done. I'll need to check the build process to see if it was due to error while creating the zip file or when copying between our internal and public repositories.

If you are able to work around the line endings and confirm the changes, I can at least close this request and work on correcting the build artifacts.

I tried the latest pull request, and I get below error.

Ah, I see it. Looks like a syntax error in the Ant script for sure. If you can, take from this branch and let me know if it works better. If things look good then I'll get it merged.

Hi Dustin,

Using the latest works, no issues and I am able to stack a single session. Thanks for your help with this!
