per host custom macros

[John P. Rouillard]

I am coming into this a bit late, but maybe a method like this would
work.  For each of my LDAP hosts I have a check_ldaps service defined
as:

  $USER1$/check_ldaps -p 636 -H `$USER1$/ip2ldapCN $HOSTADDRESS$` $ARG1$

where ip2ldapCN is:

  for i in auth1.example.com auth2.example.com auth3.example.com auth4.example.com auth4.example.com
  do
  addr=`dig +short $i`
  if [ "$addr" = "$1" ]; then
    echo $i
    exit
  fi
  done

  echo "Incorrect_address of ip2ldapCN $1" 

This loops over all auth hosts and returns the auth host name
corresponding to the host address passed in. However a similar
mechanism could be used to represent any data.

Imagine a shell script that takes two arguments: attribute_name and host
this allows you to get any attribute value into a command.

So I could write:

  $USER1$/check_ldaps -p 636 -H `$USER1$/attributes AUTHNAME $HOSTNAME$` $ARG1$

and then attributes runs:

   sed -ne "s/.*$2-$1=(.*)/\1/p" /etc/nagios/hosts/*.cfg

to extract the attribute from the host config where the attribute
looks like:

  #  host1.example.com-AUTHNAME: auth1.example.com

With some perl you could check the mtime of the *.cfg files (or the
parent directory) and reparse the config files extracting all the keys
and values into a dbm file for faster lookup.

Yes, this is a hack but it might be a useful hack and can work for
any plugin.
