Pues ahora vamos a monitorizar un servidor de almacenamiento Netapp, Para su monitorización vamos a utilizar el protocolo SNMP(Si no lo sabéis activar SNMP en una netapp AQUI tenemos un manual) y los chequeos van a ser de Memoria, CPU, Disco, PING, temperatura, ventiladores, Fallo de disco y batería.
Una vez ya tenemos instalado y configurado SNMP vamos a empezar a monitorizar.
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:
bash
define command {
command_name check_netapp_cpu
command_line /usr/bin/perl $USER1$/check_netapp3.pl -H $HOSTADDRESS$ -C public -v $ARG1$ -w $ARG2$ -c $ARG3$
}
define command{
command_name check_netapp_diskused
command_line /usr/bin/perl $USER1$/check_netapp_disk -H $HOSTADDRESS$ -C $ARG1$ -t $ARG2$ -v DISKUSED -o $ARG3$ -w $ARG4$ -c $ARG5$
}
define command{
command_name check_netapp_nvram
command_line $USER1$/check_netapp -H $HOSTADDRESS$ -P 1 -C $ARG1$ -t $ARG2$ -v NVRAM
}
define command{
command_name check_netapp_faileddisk
command_line $USER1$/check_netapp -H $HOSTADDRESS$ -P 1 -C $ARG1$ -t $ARG2$ -v FAILEDDISK
}
define command{
command_name check_netapp_fan
command_line $USER1$/check_netapp -H $HOSTADDRESS$ -P 1 -C $ARG1$ -t $ARG2$ -v FAN
}
define command{
command_name check_netapp_power
command_line $USER1$/check_netapp -H $HOSTADDRESS$ -P 1 -C $ARG1$ -t $ARG2$ -v PS
}
define command{
command_name check_netapp_temp
command_line $USER1$/check_netapp -H $HOSTADDRESS$ -P 1 -C $ARG1$ -t $ARG2$ -v TEMP
}Creamos las carpetas donde vamos a alojar los archivos de configuración
bash
mkdir /etc/nagios3/etc/cfg/Netapp/Accedemos al direcctorio
text
cd /etc/nagios3/etc/cfg/Netapp/Creamos el fichero hosts.cfg con el siguiente contenido
bash
hostgroup_name grupo-netapp
alias Almacenamiento Netapp
members redorbitanetapp_192.168.1.18
}
#Ping to hosts
define service {
use netapp-srv
hostgroup_name grupo-netapp
service_description netapp redorbitanetapp – ping
check_command check_ping!100.0,10%!500.0,20%
}
#Hosts Definition
define host {
use netapp-srv
host_name redorbitanetapp_192.168.1.18
alias redorbitanetapp
address 192.168.1.18
}Creamos el fichero templete.cfg en el cual vamos a definir los servicios.
text
define host {
name netapp-srv
flap_detection_enabled 1
notification_period 24×7
notification_options d,u,r
retain_status_information 1
retain_nonstatus_information 1
contact_groups grupo-netapp
# check_command check_command_blank
max_check_attempts 3
register 0
}
define service {
name netapp-srv
check_period 24×7
flap_detection_enabled 1
notification_period 24×7
notification_options w,u,c,r
parallelize_check 1
retain_status_information 1
retain_nonstatus_information 1
max_check_attempts 3
normal_check_interval 3
retry_check_interval 1
contact_groups grupo-netapp
register 0
}Definimos el archivo de contacto contacts.cfg
bash
define contact{
contact_name grupo-netapp
alias grupo-netapp
service_notification_period 24×7
host_notification_period 24×7
service_notification_options w,u,c,r
host_notification_options d,r
service_notification_commands notify-service-by-email
host_notification_commands notify-host-by-email
email root@localhost
}
define contactgroup {
contactgroup_name grupo-netapp
alias Grupo de Linux
members grupo-netapp
}Y por ultimo definimos los chequeos redorbitanetapp.cfg
text
define service{
use netapp-srv
host_name redorbitanetapp_192.168.1.18
service_description Ocupacion Disco Aggregado0
check_command check_netapp_diskused!public!120!aggr0!80!50
}
define service{
use netapp-srv

service_description CPULOAD
check_command check_netapp_cpu!CPULOAD!80!90
}
define service{
use netapp-srv
host_name redorbitanetapp_192.168.1.18
service_description Fallo en disco
check_command check_netapp_faileddisk!public!120

define service{

service_description Estado Bateria Nvram
check_command check_netapp_nvram!public!120

define service{

}
define service{
use netapp-srv
host_name redorbitanetapp_192.168.1.18
service_description Fuente de Alimentacion
check_command check_netapp_power!public!120
}Una vez creado el fichero tenemos que añadir la ruta de los mismos en el archivo nagios.cfg
bash
vi /etc/nagios3/nagios.cfgAl final del archivo añadimos lo siguiente:
bash

cfg_file=/etc/nagios3/etc/cfg/Netapp/contacts.cfgChequeamos para ver si no hay ningún error en los archivos de configuración
