Convert Nagios .cfg files to CSV

[madasafish]

I think this is another array exercise :-(

Here is an example of a Nagios .cfg file.

define host{
        use                     host-liberate
        check_command           check-host-alive
        max_check_attempts      3
        host_name               squid01.lang.dtv
        alias                   squid01
        address                 10.185.32.78
}

define host{
        use                     host-liberate
        check_command           check-host-alive
        max_check_attempts      3
        host_name               squid02.lang.dtv
        alias                   squid02
        address                 10.185.32.79
}


etc...

define hostgroup{
        hostgroup_name   Langley Liberate Servers
        alias            Langley Primary Site
        members          squid01.lang.dtv, squid02.lang.dtv, libmgt01.lang.dtv, libmgt02.lang.dtv
}

define hostgroup{
        hostgroup_name   Langley Content Servers
        alias            Langley Primary Site
        members          content01.lang.dtv, content02.lang.dtv
}

define hostgroup{
        hostgroup_name   Langley Database Servers
        alias            Langley Primary Site
        members          libdb01.lang.dtv, libdb02.lang.dtv
}

etc...


define service{
        use    liberate-defaults
        hostgroup_name   Langley Database Servers, Langley Liberate Servers, Langley Content Servers
        service_description  PING
        check_command   check_ping!100.0,20%!500.0,60%
}

define service{
        use     liberate-defaults
        hostgroup_name  Langley Database Servers
        service_description     LISTENER
        check_command   check_tcp!1521
}

define service{
        use     liberate-defaults
        hostgroup_name   Langley Database Servers, Langley Liberate Servers, Langley Content Servers
        service_description     CPU
        check_command   check_nrpe!check_procs
}

etc...

and what I want to output is.....

PING,libdb01.lang.dtv,libdb02.lang.dtv,squid01.lang.dtv,squid02.lang.dtv,libmgt01.lang.dtv,libmgt02.lang.dtv,content01.lang.dtv,content02.lang.dtv
LISTENER,libdb01.lang.dtv,libdb02.lang.dtv
CPU,libdb01.lang.dtv,libdb02.lang.dtv,squid01.lang.dtv,squid02.lang.dtv,libmgt01.lang.dtv,libmgt02.lang.dtv,content01.lang.dtv,content02.lang.dtv
etc...

I am using gawk version 4.0.1

As always, thanks in advance.

What have you tried so far and where in your code are you stuck ?

Hope This Helps, PH.

This is the approach so far....I know it's not right

for INFILE in lang_liberate.cfg

do

        gawk  'BEGIN{RS=""}
                if ($0 ~ "define hostgroup{") {
                        if ($1 ~ /hostgroup_name/ { hgn=$2 }
                        if ($1 ~ /members/ { mem=$2 }
                        }
                if ($0 ~ "define service{" {
                        if (tektips around....call them!)




done
exit 0

        gawk -v file=$INFILE 'BEGIN{RS="{|}"}
                $0 !~ /host_name/ {next}
                $0 !~ /check_command/ {next}
                #$0 ~ /^#|^$/ {next}
                {
                for (i=1;i<=NF;i++) {
                        x=0
                        y=0
                        if ($i ~ /host_name/) {a=$(i+1)}
                        if ($i ~ /check_command/) {b=$(i+1)}
                        if ($1 ~ /hostgroup_name/) {c=$(i+1)}
                        }

                print a","b","c

        }' $INFILE
done

What about this ?

gawk '
/^define hostgroup/{f=1}
f==1&&$1=="hostgroup_name"{sub("[ \t]*"$1"[ \t]*","");hgn=$0}
f==1&&$1=="members"{sub("[ \t]*"$1"[ \t]*","");gsub(/, /,",");thn[hgn]=$0}
/^define service/{f=2}
f==2&&$1=="hostgroup_name"{sub("[ \t]*"$1"[ \t]*","");gsub(/, /,",");for(i in thn)sub(i,thn[i]);lhn=$0}
f==2&&$1=="service_description"{print $2","lhn}
' lang_liberate.cfg

Thanks PHV...of course it works!

Wish I could understand it...
Looks like the for loop on an array is substituting the match on another array "for(i in thn)sub(i,thn)"

This for loop substitute the host groupname with their members.
