Add service name to service apply loops

[fredrik-eriksson]

Hi,

When applying services by looping over a dict (and probably array as well) it seems that no service-name is prepended. I want to add two ping tests for each interface on a host; one over ipv4 and one over ipv6; but the result is the following two objects:

apply Service for (interface => opts in host.vars.network.interfaces) to Host {
  vars.ping_address = "opts.address"
  vars.ping_cpl = getvar(host.vars.ping_cpl, 40) 
  check_command = "ping4"
  assign where "opts.address"
}

apply Service for (interface => opts in host.vars.network.interfaces) to Host {
  vars.ping_address = "opts.addressv6"
  vars.ping_cpl = getvar(host.vars.ping_cpl, 40) 
  check_command = "ping6"
  assign where "opts.addressv6"
}

This fails since the service names will be the same for both checks (the interface name). What I really want is something like this:

apply Service "ping4_" for (interface => opts in host.vars.network.interfaces) to Host {
  vars.ping_address = "opts.address"
  vars.ping_cpl = getvar(host.vars.ping_cpl, 40) 
  check_command = "ping4"
  assign where "opts.address"
}

apply Service "ping6_" for (interface => opts in host.vars.network.interfaces) to Host {
  vars.ping_address = "opts.addressv6"
  vars.ping_cpl = getvar(host.vars.ping_cpl, 40) 
  check_command = "ping6"
  assign where "opts.addressv6"
}

Which would give all objects unique names; but it doesn't seem to be supported currently.

Actually, this one isn't fixed yet. You fixed the bug with using the variables in the service; but the template still needs to be updated to allow for a unique service name when the first loop variable (interface in the example) is the same for more than one service.

apply Service for (...) to Host {
Should be
apply Service "<service_name>" for (...) to Host {

Sorry that's a syntax I donno.

'apply Service for' thru a hash is a for each loop (desc => config in host.vars.hash), desc is taken as service name by default.

you can see it in the example here:
https://docs.icinga.com/icinga2/latest/doc/module/icinga2/chapter/monitoring-basics#using-apply-for

Look at the example for apply Service "if-" for (interface_name => interface_config in host.vars.interfaces)

In my example above it's necessary to add a prefix string as both services are iterating over the same hash, but add different services: one for ipv4 and one for ipv6. Without the prefix string icinga complains about duplicate service definition.

It's not supported by the module.

You can also omit the "if-" string, then all generated service names are directly taken from the if_name variable value.
