Alert when HW Maintenance is due to expire

[choppy]

"Date HW maintenance expires" exists as an item in the Host Inventory. Is it possible to create a trigger on this?

[LenR]

I get maint date in an item, but I also create a "days left" item. I'm able to script an interface to our HW vendor to get their data via hardware serial number. Once you have a "days left" item, a trigger is easy. I use a float item, negative implies it's expired.

You could use the zabbix api to pull the inventory field and zabbix sender to update an item. Run this api script daily or as often as you need to puck up changes from the inventory data.
