Or if its easier have one server that monitors the other five and then sends an alert.
If so how would this be done?

free_huge_pages
GET_HUGE_PAGES(3) Library Functions Manual GET_HUGE_PAGES(3)
NAME
get_huge_pages, free_huge_pages - Allocate and free hugepages
SYNOPSIS
#include <hugetlbfs.h>
void *get_huge_pages(size_t len, ghp_t flags);
void free_huge_pages(void *ptr);
DESCRIPTION
get_huge_pages() allocates a memory region len bytes in size backed by hugepages. Hugepages may be of benefit to applications that use
large amounts of address space and suffer a performance hit due to TLB misses. Wall-clock time or oprofile can be used to determine if
there is a performance benefit from using hugepages or not.
The len parameter must be hugepage-aligned. In the current implementation, only the default hugepage size may be allocated via this func-
tion. Use gethugepagesize to discover what the alignment should be.
The flags argument changes the behaviour of the function. Flags may be or'd together.
GHP_DEFAULT
Allocate a region of memory of the requested length backed by hugepages of the default hugepage size. Return NULL if sufficient
pages are not available
free_huge_pages() frees a region of memory allocated by get_huge_pages(). The behaviour of the function if another pointer is used, valid
or otherwise, is undefined.
RETURN VALUE
On success, a pointer is returned to the allocated memory. On error, NULL is returned. errno will be set based on what the failure of
mmap() was due to.
