i really like to monitor my hosts with snmp, because its implemented on every device and on every OS.
sometimes you need to search a pattern in output of a special comand, eg smartctl.
this was my way to solve the problem ... have you a more elegant way ... please let me know!
- monitor disks on this host
- install needed software
apt-get install smartmontools snmpd
- configure snmpd
- vi /etc/snmp/snmpd.conf
syscontact admin@bitbull.ch rouser safereader auth rwuser safewriter priv rocommunity rEADoNLY snmpd.mydomain.com rocommunity L0cal localhost exec smart-sda /bin/sh -c "/usr/sbin/smartctl -H /dev/sda | /bin/sed '1,/===/d;/^$/d'" # exec smart-sda /bin/sh -c "/usr/sbin/smartctl -H /dev/sda | /bin/sed '/^SMART Health Status:/!d;s/.*: //'"
- /etc/init.d/snmpd restart
snmpwalk -v1 -c L0cal localhost .1.3.6.1.4.1.2021.8.1
- on nagios host
- vi /etc/nagios-plugins/config/custom.cfg
# search for pattern in snmp output define command{ command_name check_snmp_output command_line /usr/lib/nagios/plugins/check_snmp -H '$HOSTADDRESS$' -C '$ARG1$' -o '$ARG2$' -r '$ARG3$' }
- vi /etc/nagios3/conf.d/hosts-mydomain.com.cfg
define service{ use generic-service ; Inherit values from a template host_name myserver service_description Disk sda health normal_check_interval 720 check_command check_snmp_output!rEADoNLY!UCD-SNMP-MIB::extOutput.1!PASSED }
/etc/init.d/nagios3 restart
