Monitorizar VMware ESXI En Nagios

Para la monitorización de los servidores VMware ESXI vamos a instalar vSphere SDK for Perl 

Puedes ver el manual bajo Debian aquí:

https://red-orbita.com/?p=5476

Una vez instalado vSphere SDK for Perl  descargamos el chequeo que vamos a emplear para la monitorización.

wget http://git.op5.org/git/?p=nagios/op5plugins.git;a=blob_plain;f=check_vmware_api.pl

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:

vi /etc/nagios3/commands.cfg

Y añadimos lo siguiente:

###### CHECK VMWARE ################

#define command{
# command_name check_esx_cpu
# command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l cpu -s usage -w $ARG3$ -c $ARG4$
#}
#

define command{
command_name check_esx_cpu
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l cpu -s usage -w $ARG3$ -c $ARG4$
}

# check memory usage
define command{
command_name check_esx_mem
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l mem -s usage -w $ARG3$ -c $ARG4$
}

# check net usage
define command{
command_name check_esx_net
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l net -s usage -w $ARG3$ -c $ARG4$
}

# check runtime status
define command{
command_name check_esx_runtime
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l runtime -s status
}

# check io read
define command{
command_name check_esx_ioread
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l io -s read -w $ARG3$ -c $ARG4$
}

# check io write
define command{
command_name check_esx_iowrite
command_line $USER1$/check_vmware_api.pl -H $HOSTADDRESS$ -u $ARG1$ -p $ARG2$ -l io -s write -w $ARG3$ -c $ARG4$
}

Creamos las carpetas donde vamos a alojar los archivos de configuración 

mkdir /etc/nagios3/etc/cfg/VMesxi/

Accedemos al direcctorio 

cd /etc/nagios3/etc/cfg/VMesxi/

Creamos el fichero hosts.cfg con el siguiente contenido

define hostgroup {
hostgroup_name grupo-VMesxi
alias VMware Esxi Server
members esxi_192.168.1.111
}

#Ping to hosts

define service {
use VMesxi-srv
hostgroup_name grupo-VMesxi
service_description VMware Esxi Server – ping
check_command check_ping!100.0,10%!500.0,20%
}
#Hosts Definition

 

define host {
use VMesxi-srv

host_name esxi_192.168.1.111
alias VMware Esxi Server
address 192.168.1.111
}

Creamos el fichero templete.cfg en el cual vamos a definir los servicios. 

 

define host {
name VMesxi-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 VMesxi-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-VMesxi
register 0
}

 

Definimos el archivo de contacto contacts.cfg

define contact{
contact_name grupo-VMesxi
alias grupo-VMesxi
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 rokitoh@redorbita.com
}
define contactgroup {
contactgroup_name grupo-VMesxi
alias Grupo de VMware Esxi
members grupo-VMesxi
}

Y por ultimo definimos los chequeos esxi.cfg

define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi CPU Load
check_command check_esx_cpu!root!contraseña01.!80!90
}

# check memory usage
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi Memory usage
check_command check_esx_mem!root!contraseña01.!80!90
}

# check net
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi Network usage
check_command check_esx_net!root!contraseña01.!102400!204800
}

# check runtime status
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi Runtime status
check_command check_esx_runtime!root!contraseña01.
}

# check io read
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi IO read
check_command check_esx_ioread!root!contraseña01.!40!90
}

# check io write
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description ESXi IO write
check_command check_esx_iowrite!root!contraseña01.!40!90
}

Una vez creado el fichero tenemos que añadir la ruta de los mismos en el archivo nagios.cfg

vi /etc/nagios3/nagios.cfg

Al final del archivo añadimos lo siguiente:

############## Monitorización VMware Esxi Server #############

cfg_file=/etc/nagios3/etc/cfg/VMesxi/templete.cfg
cfg_file=/etc/nagios3/etc/cfg/VMesxi/hosts.cfg
cfg_file=/etc/nagios3/etc/cfg/VMesxi/esxi.cfg
cfg_file=/etc/nagios3/etc/cfg/VMesxi/contacts.cfg

Chequeamos para ver si no hay ningún error en los archivos de configuración

rokitoh@nagios:/etc/nagios3/etc/cfg # nagios3 -v /etc/nagios3/nagios.cfg
