boinc_processes

Sadly there is no documentation for this plugin

#!/usr/bin/perl -w
#
# Plugin for monitoring boinc processes
#
# Parameters:
#
#	password	-- The password for RPC authentication
#			   (default: boinc_cmd will look for a file
#			   'gui_rpc_auth.cfg' and use the password in it)
#       host 		-- the host to connect to (default: localhost)
#	port 		-- optional (default: 31416)
#
# This plugin can monitor boinc processes running on local/remote machines.
# You can see the progress on various projects.
