Description of problem: - We have the Logical Volumes limitation in a Storage Domain in our official Documentation https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.5/html/Technical_Guide/Storage_domain_limitations.html - We have the warning at the RHEV-M events "The number of LVs on the domain XXX exceeded 300, you are approaching the limit where performance may degrade." But many customers do not access frequently the admin portal and do not get notified regarding that. Feature Request: Can we have an email notification for this as well? Also it would be good to have in Storage Domain's "General" tab, the "Total number of LVs" (without this, the admin will not know how many disks he has to move to another Storage Domain)* Also. maybe a pop-up warning when the admin is trying to add one more disk/snapshot.* *Let me know if we need separate RFEs for these

Oved - don't we have a notifier mechanism that can send an email based on an event?
There is the engine-notifier, but there is no option yet for that event. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.3/html-single/Administration_Guide/index.html#chap-Event_Notifications
There is a mechanism. It should be simple to add this event there. Once you assign someone for that, have him sit with Moti, and he will give a proper example.

Thanks Oved! I was under the [wrong] impression that there's a generic connection between AuditLogs and notifications, and the customer just needs to set up the email details. Once we start handling 4.0 features, I'll send someone your way. Thanks again!
Hi Idan, Is the 350 value hardcoded? If not where can it be changed (DB / XML)?
Hi Natalie, Sorry for the delay, I was on PTO the past week. The default number is 300 and it can be found on the DB: engine=> SELECT * from vdc_options WHERE option_name = 'AlertOnNumberOfLVs'; option_id | option_name | option_value | version -----------+--------------------+--------------+--------- 368 | AlertOnNumberOfLVs | 300 | general

It's a trivial patch - but I wonder whether we want to make this visible to our customers. Yaniv D - your two cents?

It's also a matter of how conservative the customer is. Users would like to change this.

QA: Note that for the context of THIS bug, having it available via engine-config.sh is just a nicety. THIS bug can be verified by querying (or even updating) the database directly.
Moving target release to RC to include the latest fix.
