Trigger question

[pesadilla]

UPDATE: triggers with .delta(0) doesn't work in 1.4.2? are gray and trigger is unknown




I'm using snmpv1 template. All triggers are grey except

ifDescrX on {HOSTNAME} has Changed (are green)
ipDefaultTTL on {HOSTNAME} is too High (green)
ipForwarding on {HOSTNAME} is too High (green)
lmemRomID on {HOSTNAME} has Changed (always red)
sysName on {HOSTNAME} has Changed (green)

and in "Latest data", "Last check" it's ok, and sysname (red trigger) history is:
