Hi Antony,
You can try this:
1. vi /etc/icinga2/functions.conf
2. Paste
globals.get_display_name = function(h) {
d = get_host(h).display_name
if (d) {
log(LogInformation, "get_display_name", "Display name found!")
return d
}
log(LogWarning, "get_display_name", "Display name not found!")
return "None"
}
3. vi /etc/icinga2/icinga2.conf
4. Add include "functions.conf" under include "constants.conf"
/**
* The constants.conf defines global constants.
*/
include "constants.conf"
include "functions.conf"
5. service icinga2 reload
6. use can now use get_display_name("hostname")

Yes.

Right. You can also do
icinga2 console --connect
'https://urldefense.proofpoint.com/v2/url?u=https-3A__your-5Fuser-3Ayour-5Fpass-40localhost-3A5665_&d=DwIFbA&c=imBPVzF25OnBgGmVOlcsiEgHoG1i6YHLR0Sj_gZ4adc&r=dLhm7TMuuUAhZaaelXPoEPyMbTqxkar-G5Ayny5-yLE&m=5OuMETuzhUdDcMUfQweHVCEllAdzX4AqRSzGCKbbJVU&s=2RUDJpS2NBOOAxKGNDdBIkuCXGHuviJ2xHaVgfu0ViI&e='
so long as you don't mind the password being visible in a process listing to
other users on the machine.

Agreed (in principle, anyway).

Yes, I can do everything I want to there:
<1> => a=get_host("first.server.com").vars.neighbour
null
<2> => a
"second.server.com"
<3> => b=get_host(get_host("first.server.com").vars.neighbour).display_name
null
<4> => b
"HA Pair: Berlin"
And, "HA Pair: Berlin" is indeed the display_name for "second.server.com",
which you can see is the value in vars.neighbour for "first.server.com"
So, I can get what I want in the console; it just doesn't work inside the code.

Nice idea, but I'm still stuck about how to implement these commands where
Ineed them to work :(
