>Description:
	The nagios-pf-plugin port was expired as the website was no
	longer operating. But the project on GitHub is up. I re did
	the port to use GitHub.
>How-To-Repeat:
	Wish to monitor how many pf state table entries are in use
	with Nagios.
>Fix:

Xcheck_pf has been installed to %%PREFIX%%/libexec/nagios.
X
Xcheck_pf needs read permission to the pf(4) pseudo-device, i.e. /dev/pf.
X
XAssuming check_pf will be run by user `nagios', the following will work:
X
X	# chmod 640 /dev/pf
X	# chgrp nagios /dev/pf
X
XTo make sure the change persists across reboots, add the following
Xto /etc/devfs.conf:
X
X	# nrpe2/nagios needs to be able to read statistics
X	own     pf    root:nagios
X	perm    pf    0640
X	
XPlease refer to the online documentation for additional information.

Xcheck_pf is a plugin intended for use with the Nagios network
Xmonitoring system.  This plugin checks the status of PF, the OpenBSD
Xpacket filter, and compares the current state count to given or default
Xthresholds, returning the result.  It is written in C.
