 Description  « Hide
Left list of resources on monitoring page has a popup window that let's you see the # of alerts and oob, with a "+" that let's you add metrics to the summary graphs page.

However, all of the content of all of the popups are loaded at the time the page is loaded. For a page that has to show a large number of resources, this page load time can be very long. We need to only load the popups on-demand. If someone asks to see the information by hovering over the blue-right-arrow icon, only then should we load the content for that popup only.

Please define "very long".
We are in the very few seconds for 1000 resources area (iirc).

But as we are going to rewrite big parts of that anyway, we can surely have a look into this.

I think its more than a few seconds once you have alot of data in the database (alerts and OOBs). I don't have a current environment setup that demonstrates this, however.

Another side effect of this is that the database is clobbered when you go to a page like this since it has to run those expensive queries for each resource in the left-hand tree.

see oracle-em.jpg - took 5 minutes to complete the query (I had closed my browser becaues otherwise, the refresh would continue to have executed the query)

i had 198 linux platform resources in my compat group.
Left side wasn't too long in rendering but the summary graphs clobbered the DB (see attachment). The query took too long - the page refreshed before it could render the graphs.

would like this to be looked at for 1.2
