Total Bandwidth Trigger?

[linuxdr]

I have Zabbix setup to record bandwidth in several datacenters. I need to have an alert if our total bandwidth across these routers hits a number. Is this possible currently? Also, I assume the way I'm trying is working:

({BI4K_East_Coast_1:.1.3.6.1.2.1.2.2.1.13.8.last(0 )}+{BI4K_West_Coast_1:.1.3.6.1.2.1.2.2.1.16.1.last (0)})>200000000

I get the following error:

No such host (BI4K_West_Coast_1) or monitored parameter (.1.3.6.1.2.1.2.2.1.16.1)

Two natural questions. Do you have:

1. host "BI4K_West_Coast_1"?
2. item having key ".1.3.6.1.2.1.2.2.1.16.1"?

Yes, it is currently being graphed.

Please, give me a screenshot of the item details. Thanks!
