Expose Hardware Sensor values to a variable that can be used in an action like email or create ticket
I believe you can already, its just not that easy to find or interpret. Although it might be easier to develop a SWQL query and use that, in an Alert definition you can alert on a "Hardware Sensor (Node)" (as well as other Hardware Sensor types) and choose what fields you want and such from there. It's the first dropdown in the "TRIGGER CONDITON" for an alert, you have to go past the "normal" stuff like Node or Volume to find them. From the alert you can then send an email or create a ticket with an action on the "Trigger Actions" page.
