The "All Triggered Alerts" box on the summary page works great for node alerts, but doesn't show the Node ID for hardware components. See below (NCM 11.5RC3):
In order to find out what node is actually having the issue, you need to click on the correct spot ("Fan 5"). If you instead click on "Alert me when ...", it brings you to a page that still does not tell you which node it is (at least not in the title):
I recommend that the 'Node Name' be added to both of these.
