Macro name in trigger

[maxxer]

I'm trying to have a trigger check the IP host against a DNS query. I did the DNS query item but I'm missing how to check the returned value in a trigger.

{Template YO verifica host DNS:net.dns.record[1.0.0.1,{$DNS_HOST},A].last()}<>{$DNS_EXPECTED_IP}

won't work because the check returns something like host.name.it A 1.3.2.3.

I also tried

{{ITEM.VALUE}.regsub([0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}+, \1)}

to strip out all the unnecessary output and check against the IP value only but again it's not accepted.

Any hint?
thanks

First, triggers can only compare numbers, not strings (before version 5).
Second use a trigger construction like
{Template YO verifica host DNS:net.dns.record[1.0.0.1,{$DNS_HOST},A].regexp({$DNS_EXPECTED_IP_REGEX})} >0
{$DNS_EXPECTED_IP_REGEX} - a macro containing a regular expression describing the response you need.

Great, thanks!

Isn't possible to have the macro with the IP only and wrap the rest around in the trigger definition?

Read the documentation carefully and try it out.
