Nagios checks for FreeBSD jails

The pkg-base-audit.sh script requires security/base-audit

pkg-audit.sh requires ports-mgmt/pkg, which should be on every system using pkg.

I used these settings in /etc/periodic.conf:

# for security/405.pkg-base-audit
security_status_baseaudit_enable="YES"
security_status_baseaudit_jails="*"

# for 410.pkg-audit
security_status_pkgaudit_expiry=1

# for many scripts including 405 & 410
pkg_jails='*'

I install pkg-audit.sh and pkg-base-audit.sh at /usr/local/libexec/nagios-custom

I add these entries to /usr/local/etc/nrpe.cfg

$ grep audit /usr/local/etc/nrpe.cfg
command[check_pkg_audit]    =/usr/local/bin/sudo /usr/local/libexec/nagios-custom/pkg-audit.sh
command[check_base_audit]   =/usr/local/bin/sudo /usr/local/libexec/nagios-custom/pkg-base-audit.sh

I add these entries via sudo:

$ sudo grep audit /usr/local/etc/sudoers
nagios   ALL=(ALL) NOPASSWD:/usr/local/libexec/nagios-custom/pkg-audit.sh
nagios   ALL=(ALL) NOPASSWD:/usr/local/libexec/nagios-custom/pkg-base-audit.sh

These services are defined in /usr/local/etc/services.cfg:

define service {
        #NAGIOSQL_CONFIG_NAME           FreeBSD_Server
        hostgroup_name                  FreeBSD Server
