The Nagios Service Check Acceptor Forwarding Engine (NSCAFE) can be used as a direct substitute for the standard NSCA addon, providing significant additional functionality useful in monitoring large installations.
SCAFE (Nagios(R) Service Check Acceptor Forwarding Engine) is a drop-in replacement for the standard Nagios(R) NSCA tool that adds significant functionality useful in monitoring large installations. Among the enhancements are:

o NSCAFE automatically forwards service check and other messages received from a remote host both to Nagios(R) itself and/or to another instance of NSCAFE running on another host.

o NSCAFE caches service check and other messages in a local XML datastore, so if the connection to a forward host goes down all checks that occur during the down time are stored and can be queued up
to forward once the connection is reestablished.

o NSCAFE can be set to "update on state change only", minimizing congestion on the destination or "parent" Nagios(R) server.

o NSCAFE can send a message to execute any Nagios(R) command on any given Nagios(R) server from any allowed host.

o NSCAFE accepts regular expressions in its configuration strings.

o NSCAFE is configured using an external configuration file that is upward compatible with NSCA's nsca.cfg.

o NSCAFE can be set to strip performance data from a service check before forwarding it.

=================================

NSCAFE consists of two components:

1) a java module that accepts messages from the machines being monitored, forwarding the messages on to a local or remote Nagios(R) instance (or another instance of the java module.)

2) a perl script resident on each machine being monitored that sends service check results or commands to an instance of the java module.

These two components can be used as a direct substitutes for their NSCA equivalents (send_nsca, nsca.)
