Esta vez vamos a realizar un manual de como monitorizar Datastores VMware ESXI en nagios.
Para ello vamos a partir de la siguiente monitorización que ya realizamos en su día:
https://red-orbita.com/?p=5551
Descargamos el chequeo
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
define command{
command_name check_esx_datastore
command_line /usr/bin/perl /usr/local/nagios/libexec/check_vmware_api.pl -H $ARG1$ -u $ARG2$ -p $ARG3$ -l VMFS -s $ARG4$ -w $ARG5$ -c $ARG6$
}
Accedemos al archivo de configuración donde se encuentra la monitorización de nuestro ESXI
vi /etc/nagios3/etc/cfg/VMesxi/esxi.cfg
Añadimos el siguiente chequeo:
Sintaxis:
check_esx_datastore!<SERVIDOR>!<USUARIO>!<CONTRASEÑA>!'<DATASTORE>’!<CAPACIDAD WARNING>:!<CAPACIDAD CRITICAL>:
chequeo:
define service{
use VMesxi-srv
host_name esxi_192.168.1.111
service_description Ocupacion Datastoragecheck_command check_esx_datastore!esxi!root!contraseña.!’datastore_1′!150000:!100000:
}
Chequeamos para ver si no hay ningún error en los archivos de configuración
