Vamos a ver como monitorizar procesos nagios, para ello vamos a partir de los manuales que hemos realizado sobre monitorización básica en Windows y GNU/Linux
Monitorización basica de UNIX – *BSD – GNU/Linux en Nagios
Monitorización basica de Windows en Nagios
Definir los comandos :
para definir tenemos que añadir los siguientes comandos al fichero commands.cfg, este fichero estará… dependiendo de la instalación que habríais realizado
bash
vi /etc/nagios3/commands.cfgY añadimos lo siguiente:
define command{
command_name check_process_snmp
command_line /usr/bin/perl $USER1$/check_snmp_process.pl -H $HOSTADDRESS$ -C $ARG1$ -n $ARG2$ -w $ARG3$ -c $ARG4$
}
Accedemos al direcctorio
Accedemos al directorio donde se encuentran los archivos de configuración en mi caso (/etc/nagios3/etc/cfg/Linux/)
text
cd /etc/nagios3/etc/cfg/LinuxAñadimos el nuevo chequeo.
bash
vi cacti.cfgAgregamos lo siguiente:
text
define service {
use linux-srv
host_name cacti_192.168.1.111
service_description Proceso MySQLD
check_command check_process_snmp!redorbita!mysqld!0!0
}
define service {
use linux-srv
host_name cacti_192.168.1.111
service_description Proceso apache2
check_command check_process_snmp!redorbita!apache2!0!0
}También se puede añadir un control en la monitorización de los numero de procesos que se ejecutan, si pasa el numero de procesos definidos saltara la alarma, Ejemplo:
text
define service {
use linux-srv
host_name cacti_192.168.1.111
service_description Proceso MySQLD
check_command check_process_snmp!redorbita!mysqld!0,2!0,2
}
define service {
use linux-srv
host_name cacti_192.168.1.111
service_description Proceso Apache2
check_command check_process_snmp!redorbita!apache2!0,30!0,50
}Ahora vamos a realizar exactamente lo mismo con la monitorización en Microsoft Windows.
Accedemos al directorio donde se encuentran los archivos de configuración
text
cd /etc/nagios3/etc/cfg/WindowsAñadimos el nuevo chequeo.
text
vi cpd01.cfgAgregamos lo siguiente:
text
define service {
use windows-srv
host_name cpd_192.168.1.112
service_description Proceso IIS
check_command check_process_snmp!redorbita!minetinfo.exe!0!0
}chequeamos para ver si no hay ningún error en los archivos de configuración

Reloading nagios3 monitoring daemon configuration files: nagios3.Abrimos nagios en nuestro navegador favorito y si todo a salido bien lo tendríamos que tener OK!
Un saludo, rokitoh
