Sounds like a rather straightforward check plugin. Write a check_plugin
that accepts parameters on the command line that uniquely identifies the
host and service that nagios is trying to get status information for
(see the docs for Using Macros in Commands
http://nagios.sourceforge.net/docs/2_0/macros.html). Have it parse your
files for status information and return relevant status information and
exit code back to nagios (see the Developer Guidelines at
http://nagiosplug.sf.net). Set this plugin as the check_command for the
relevant hosts/services.

Alternately, you can have an external script submit passive results back
to nagios via the external command file
(http://nagios.sourceforge.net/docs/2_0/passivechecks.html,
PROCESS_HOST_CHECK_RESULT and PROCESS_SERVICE_CHECK_RESULT of
http://www.nagios.org/developerinfo/externalcommands/commandinfo.php?com
mand_id=114).

Hth,
