------------------------------------
Sliders are working, values are passing to controller.
I am working on filtering and computation of cache array that should be really shown in dependence on set values on sliders.

> In our admin console current single cluster view page does not contain the following functionality that should be implemented:
> * -Zoom in/out-
> * Node availability/detail
> * Filter by metrics (node view)
> * Filter by metrics (cache view)
> * Search node (search as you type)
> * Search cache (search as you type)

[JBoss JIRA] (ISPN-5238) Maintain session in ispn-mgmt-console (ctrl+R)
by Tomas Sykora (JIRA)
[ https://issues.jboss.org/browse/ISPN-5238?page=com.atlassian.jira.plugin.... ]
Tomas Sykora commented on ISPN-5238:
------------------------------------
[~vblagojevic] we will need to do something with this soon. It will speed up development tremendously. The thing is that node is running nodemon that is watches for changes in files in an application. When file is changed (eg. cluster.html) it reloads page, source code and immediately shows changes in your browser.
Now, however, after a change, we are losing all our scope and we are not logged in application anymore. Page refreshes and there are only AngularJS brackects with empty properties shown on page. Also, some users might want to hit ctrl+R from time to time.
We need to come up with some solution soon, implement it and integrate it asap, so we can build more code more easily.

> When you reload a page in Infinispan Management Console data is lost and you need to re-login. We need to make sure that the session is maintained properly and operations like ctrl+R, F5 etc. does not affect behaviour negatively.
> It will also help with development and testing when you need to reload a page to see some changes from time to time.
> I did a small research around this topic and made some experiments but I was not able to achieve what I wanted. Maybe we can come up with even different approach.
> Anyway I suppose we can stick to the idea that ctrl+R should just reload the page and data successfully.

[JBoss JIRA] (ISPN-5274) Inconsistent data after transaction rollback (with success on originator)
by Dan Berindei (JIRA)
[ https://issues.jboss.org/browse/ISPN-5274?page=com.atlassian.jira.plugin.... ]
Dan Berindei commented on ISPN-5274:
------------------------------------
Agree, it is probably better to fail the transaction in this situation. The transaction still won't be atomic, as some of the nodes will have already committed it, but it would be better than the current outcome.
I believe it will be enough to fail the transaction if one of the commit command's targets is missing from the view and the local partition is unavailable. To minimize the chances of a partial commit, we should perform the check before sending the commit command, but we also need to run it after - in case the cluster split right then.
The "after" check could create some false positives because it won't have access to the actual responses to the commit command, so the partition could become degraded right after the commit succeeded. This will leave the cache inconsistent, but I think it is an acceptable risk for now.
