Here, we are using the nodata() function the other way around—even if the last entry contains errors, the trigger would switch to the OK state if there were no other values in the last 10 minutes.

Tip

We also discussed triggers that time out in Chapter 6, Detecting Problems with Triggers, in the Triggers that time out section.

If the item receives error lines only, we could use an expression like the one above, but we could also simplify it. In this case, just having any value is a problem situation, so we would use the reversed nodata() function again and alert on values being present:

{host.item.nodata(10m)}=0
