How to get the HOST.ID in an item key

[FH26]

Hey, I'd like to use the HOST.ID Macro in an item key.
Sadly this doesnt work, only HOST.HOST, but I need the ID.
Is there any reason this doesnt work and any know workaround?

I guess it is not working there, as it not made to work there...

If you think this might be useful, you can submit a request for that.

For workarounds, there's too little information about what you want to achieve...

I've programmed a script to periodically update the hosts name to a specific value we're receiving over SNMP.
This script takes the Host ID and then changes the name over the API.
I wanted the script to be run by an External Check item and the item calls the script (./updatehostnames.sh {HOST.ID} ).
I want every host to have this item so that the name is always up to date.
The script works perfectly fine, but I sadly can't call it since items don't allow the {HOST.ID}-Macro.

ok .. so is that value stored in one of items? Basically you could create a trigger, something like "hostname changed" and then use {HOST.ID} in action associated with that trigger...

{HOST.ID}
