You've seen answers on how to handle the remote communication. As far  
as the log parsing, you're not the first to want to do that. check_log  
is included in the standard plugins and there are others I am aware of  
that can be found by searching Nagios Exchange or the web.

# Usage: ./check_log <log_file> <old_log_file> <pattern>
#
# Description:
#
# This plugin will scan a log file (specified by the <log_file> option)
# for a specific pattern (specified by the <pattern> option).   
Successive
# calls to the plugin script will only report *new* pattern matches in  
the
# log file, since an copy of the log file from the previous run is saved
# to <old_log_file>.
