You can do something like:

Create a file with a list of the hosts you want to query:
Code:
$> vi hostlist
host1
host2
host3
..

Then take some code:
Code:
PATTERN=mypattern
while read LINE; do
     ssh -n $LINE "grep -c $PATTERN /path/to/file"
done < hostlist |\
awk -v pattern="$PATTERN" '
     {sum+=$1}
     END{
          print "Pattern:",pattern
          print "Sum:",sum
     }
'

krb5_free_krbhst

KRB5_GET_KRBHST(3)					   BSD Library Functions Manual 					KRB5_GET_KRBHST(3)

NAME

     krb5_get_krbhst, krb5_get_krb_admin_hst, krb5_get_krb_changepw_hst, krb5_get_krb524hst, krb5_free_krbhst -- lookup Kerberos KDC hosts

LIBRARY

     Kerberos 5 Library (libkrb5, -lkrb5)

SYNOPSIS

     #include <krb5.h>

     krb5_error_code
     krb5_get_krbhst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb_admin_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb_changepw_hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_get_krb524hst(krb5_context context, const krb5_realm *realm, char ***hostlist);

     krb5_error_code
     krb5_free_krbhst(krb5_context context, char **hostlist);

DESCRIPTION

     These functions implement the old API to get a list of Kerberos hosts, and are thus similar to the krb5_krbhst_init() functions. However,
     since these functions returns all hosts in one go, they potentially have to do more lookups than necessary. These functions remain for com-
     patibility reasons.

     After a call to one of these functions, hostlist is a NULL terminated list of strings, pointing to the requested Kerberos hosts. These should
     be freed with krb5_free_krbhst() when done with.

EXAMPLES

     The following code will print the KDCs of the realm ``MY.REALM''.

	   char **hosts, **p;
	   krb5_get_krbhst(context, "MY.REALM", &hosts);
	   for(p = hosts; *p; p++)
	       printf("%s
", *p);
	   krb5_free_krbhst(context, hosts);
