Nagios-plugin

Tämä sivu on listaus erilaisista Nagios Plugineista joita voi asentaa Nagiokseen Icingaan (icinga2). Lisäessä Nagiokseen tai Icingaan plugini muista konfiguroida se sinne. Katso enemmän ohjeita Nagioksen ja Icinga2 ohjeesta.

check_memory

check_memory plugin ei ole oletuksena nagios-plugineissa mutta tällä kätevällä pluginilla tarkistetaan muistin tilaa.

 apt-get install libnagios-plugin-perl

Lataa ja konfiguroidaan plugin

 cd /usr/lib/nagios/plugins/
 wget https://raw.githubusercontent.com/dermoth/misc-code/master/nagios/plugins/check_memory
 chmod 775 check_memory

Tämän jälkeen lisää Icingaan /etc/icinga2/conf.d/commands.conf tiedostoon

object CheckCommand "check_memory" {
        import "plugin-check-command"
        command = [ PluginDir + "/check_memory" ] //constants.conf -> const PluginDir
        arguments = {
        }
}

check_diskstat

Pluginilla tulostetaan tiedot levyn käytöstä

Esimerkki Output:

 summary: 0 io/s, read 0 sectors (0kB/s)​, write 1256 sectors (6kB/s)​, queue size 0 in 90 seconds

Lataa plugini ja siirrä Nagios plugin hakemistoon

wget https://raw.github.com/mclarkson/check_diskstat/master/check_diskstat.sh
chmod +x check_diskstat.sh
mv check_diskstat.sh /usr/lib/nagios/plugins/check_diskstat

Testaa ./check_diskstat -d sda -W 10 -C 20

Lisää Icingaan

object CheckCommand "check_diskstat" {
        import "plugin-check-command"
        command = [ PluginDir + "/check_diskstat" ] //constants.conf -> const PluginDir
        arguments = {
                "-d" = "$diskstat_name$"
                "-W" = "$diskstat_warn$"
                "-C" = "$diskstat_crit$"

        }
}

ja muuttujat hosteihin

   vars.diskstat_name = "sda"
   vars.diskstat_warn = "10"
   vars.diskstat_crit = "20"

check_openvpn

Lataa täältä: https://exchange.nagios.org/directory/Plugins/Security/VPN-Software/check_openvpn_pl/details

Asennus

 aptitude install libnet-telnet-perl

Kopioi check_openvpn.pl /usr/lib/nagios/plugins/check_openvpn ja anna nagios/icinga käyttäjälle suoritusoikeudet.

Lisää Icingaan commands.conf tiedostoon

object CheckCommand "check_openvpn" {
        import "plugin-check-command"
        command = [ PluginDir + "/check_openvpn" ] //constants.conf -> const PluginDir
        arguments = {
                "-H" = "$openvpn_hostname$" //OpenVPN Server IP or Hostname
                "-p" = "$openvpn_port$" //OpenVPN Management Port
                "-P" = "$openvpn_password$" //Password for the management interface of the openvpn server.
                "-t" = "$openvpn_timeout$ //Timeout for the connection attempt. Optional, default 10 seconds.
                "-i" = "$openvpn_ip" //Prints the IP address of the remote client instead of the common name.
                "-n" = "$openvpn_numeric$" //Prints the number of clients connected to the openvpn server.
                "-C" = "$openvpn_commonname$" //The common name, as it is specified in the client certificate, who is wanted to check.
                "-r" = "$openvpn_remoteip$" //The client remote ip address who is wanted to check.
                "-c" = "$openvpn_crit$" //Exits with CRITICAL status if the client specified by the common name or the remote ip address is not connected
                "-w" = "$openvpn_warn$" //Exits with WARNING status if the client specified by the common name or the remote ip address is not connected
