Monitor VMware ESXI datastores in nagios

To do this, we are going to start from the following monitoring that we already carried out in the past: https://red-orbita.com/?p ===

This time we are going to make a manual on how to monitor VMware ESXI Datastores in Nagios.

To do this, we are going to start from the following monitoring that we already carried out in the past:

https://red-orbita.com/?p=5551

We download the check

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

Define the commands:

To define we have to add the following commands to the commands.cfg file, this file will be... depending on the installation that you would have performed:

Bash

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 $ARG6$

}

We access the configuration file where the monitoring of our ESXI is located.

Bash

vi /etc/nagios3/etc/cfg/VMesxi/esxi.cfg

We add the following check:

Syntax:

text

check_esx_datastore!<SERVIDOR>!<USUARIO>!<CONTRASEÑA>!'<DATASTORE>’!<CAPACIDAD WARNING>:!<CAPACIDAD CRITICAL>:

check:

text

define service{

use VMesxi-srv

host_name esxi_192.168.1.111

service_description Ocupacion Datastorage
check_command                   check_esx_datastore!esxi!root!contraseña.!’datastore_1′!150000:!100000:

}

We check to see if there are no errors in the configuration files

Bash

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

And we restart nagios

Bash

rokitoh@nagios:/etc/nagios3/etc/cfg # /etc/init.d/nagios3 reload

Reloading nagios3 monitoring daemon configuration files: nagios3.

rokitoh@nagios:/etc/nagios3/etc/cfg #

We open nagios in our favorite browser and if everything went well we should have it OK!
