Description Jerome Marc 2017-04-19 18:35:40 UTC

Description of problem:
In a large environment, the number of events in the UI Notifications of CloudForms keeps increasing (2000+ is normal in the MBU lab). There does not seem to be a max number of events loaded and presented in the UI. This causes latency in loading up the CloudForms UI when the number of events is high.

Workaround is to manually clean the list up. This is a pain. I suggest loading a certain number of events and offer a --more-- link to load the rest.

Version-Release number of selected component (if applicable):
5.7.1.3.20170221135006_818f133 

How reproducible:
Always

Steps to Reproduce:
1. Perform tasks causing events to load in the CloudForms UI notification

Actual results:
UI experiences latencies when the number of events is large in the UI notifications.

Expected results:
UI should remain the same despite the large amount of events.

Comment 2 Jerome Marc 2017-06-06 21:49:26 UTC

I recently was experiencing UI latency in CF4.5. I deleted the notifications with the following command and everything became responsive again.

vmdb_production=# delete from notifications;
DELETE 5824

There seems to be an issue in the way notifications are loaded/handled?

I think this is not just RFE as it is impacting production availability when notifications numbers get high. In large customer env, it will be just short amount of time to cause UI loading issue by nature.

One of our customer deployed workaround suggested in comment#2 and their business is back but urgently seeking for fix this issue as this is not just good to have feature request.
