Hi Minwook,

Why do you think the request should pass through the Vitrage API? Why can’t vitrage-dashboard call the check component directly?

And another question: what should happen if the user closes the check window before the checks are over? I assume that the checks will finish, but the user won’t be able to see the results?

Thanks,
Ifat.

Hello Ifat and Vitrage team.

I would like to explain more about the implementation part of the mail I sent last time.

The flow is as follows.

Vitrage-dashboard (action-list-panel) -> Vitrage-api -> check component

The last time I mentioned it as api-handler, it would be better to call the check component directly from Vitarge-api without having to use it.

I hope this helps you understand.

Thank you

Best Regards,
Minwook.

Hello Ifat,

Thanks for your reply. : )

This proposal is a proposal that we expect to be useful from a user perspective.

From a manager's point of view, we need an implementation that minimizes the overhead incurred by the proposal.

The answers to some of your questions are:


•       I assume that these checks will not be implemented in Vitrage, and the results will not be stored in Vitrage, right? Vitrage role is to be a place where it is easy and intuitive for the user to execute external actions/checks.

Yes, that's right. We do not need to save it to Vitrage because we just need to check the results.
However, it is possible to implement the function directly in Vitrage-dashboard separately from Vitrage like add-action-list panel,
but it seems that it is not enough to implement all the functions.
If you do not mind, we will have the following flow.

1. The user requests the check action from the vitrage-dashboard (add-action-list-panel).
2. Call the check component through the vitrage's API handler.
3. The check component executes the command and returns the result.

Because it is my opinion only, please tell us if there is an unnecessary part. :)


•       Do you expect the user to click an entity, select an action to run (e.g. ‘P2P check’), and wait by the open panel for the results? What if the user switches to another menu before the check is done? What if the user asks to run an additional check in parallel? What if the user wants to see again a previous result?


My idea was to select the task, wait for the results in an open panel, and then instantly see it in the panel.
If we switch to another menu before the scan is complete, we will not be able to see the results.
Parallel checking is a matter of fact. (This can cause excessive overhead.)
For earlier results, it may be okay to temporarily save the open panel until we exit the panel. We can see the previous results through the temporary saved results.


•       Any thoughts of what component will implement those checks? Or maybe these will be just scripts?

I think I implement a separate component to request it.


•       It could be nice if, as a result of an action check, a new alarm will be raised in Vitrage. A specific alarm with the additional details that were found. However, it might not be trivial to implement it. We could think about it as phase #2.


It is expected to be really good. It would be very useful if an Entity-Graph generates an alarm based on the check result.
I think that part will be able to talk in detail later.
My answer is my opinions and assumptions.
If you think my implementation is wrong, or an inefficient implementation, please do not hesitate to tell me.

Thanks.

Best Regards,
Minwook.

Hi Minwook,

I think that from a user’s perspective, these are very good ideas.

I have some questions regarding the UX and the implementation, since I’m trying to think what could be the best way to execute such actions from Vitrage.


·         I assume that these checks will not be implemented in Vitrage, and the results will not be stored in Vitrage, right? Vitrage role is to be a place where it is easy and intuitive for the user to execute external actions/checks.

Subject: [openstack-dev] [Vitrage] New proposal for analysis.

Hello Vitrage team.

I am currently working on the Vitrage-Dashboard proposal for the ‘Add action list panel for entity click action’.
(https://review.openstack.org/#/c/531141/)

I would like to make a new proposal based on the action list panel mentioned above.

The new proposal is to provide multidimensional analysis capabilities in several entities that make up the infrastructure in the entity graph.

Vitrage's entity-graph allows us to efficiently monitor alarms from various monitoring tools.

In the current state, when there is a problem with the VM and Host, or when we want to check the status, we need to access the console individually for each VM and Host.

This situation causes unnecessary behavior when the number of VMs and hosts increases.

My new suggestion is that if we have a large number of vm and host, we do not need to directly connect to each VM, host console to enter the system command.

Instead, we can send a system command to VM and hosts in the cloud through this proposal. It is only checking results.

I have written some use-cases for an efficient explanation of the function.

From an implementation perspective, the goals of the proposal are:


1.     To execute commands without installing any Agent / Client that can cause load on VM, Host.

2. I want to provide a simple UI so that users or administrators can get the desired information to multiple VMs and hosts.

3. I want to be able to grasp the results at a glance.

4. I want to implement a component that can support many additional scenarios in plug-in format.

I would be happy if you could comment on the proposal or ask questions.

Thanks.

Best Regards,
Minwook.
