Nice fine. My checks using check_ide_smart do use sudo.
define command{
command_name check_smartd
command_line /usr/bin/sudo /usr/lib/nagios/plugins/check_ide_smart -d $ARG1$ -n
}
define service{
use generic-service
host_name localhost
service_description SMART status 2
check_command check_smartd!/dev/disk/by-id/scsi-SATA_WDC_WD6401AALS-_WD-WCASY7715793
}
/etc/sudoers
nagios ALL = NOPASSWD: /usr/lib/nagios/plugins/check_ide_smart
For the example SECURITY email I sent (dated Nov 28, 21:29:59), /var/log/auth.log has a record:
Nov 28 21:29:59 artichoke sudo: nagios : TTY=unknown ; PWD=/ ; USER=root ; COMMAND=/usr/lib/nagios/plugins/check_ide_smart -d /dev/disk/by-id/scsi-SATA_WDC_WD6401AALS-_WD-WCASY7715793 -n
As far as I can tell, that looks normal. The smartd checks were never in error while my network was down. I'm only using local passwd/group/shadow files for authentication, no LDAP or yp or other external authentication service.
