Nagios Support Forum

Hi Nagios,
I use Nagios 4.3.2 version. I have configure that the site can monitor my VMWare hosts. It works fine Please see attachment. Now I only monitor "host_alive":

# my example


###############################################################################
#
# BELOW HOST FOR GROUP DEFINITIONS
#
###############################################################################

define hostgroup{
hostgroup_name vmware-servers ; The name of the hostgroup
alias vmware servers ; Long name of the group
members VMWARE6,VMWARE7,VMWARE8,VMWARE9
}


define host {
host_name VMWARE6
use linux-server
alias VMWARE6
address xxx.xx.xx.xx
hostgroups vmware-servers
max_check_attempts 3
check_period 24x7
check_command check-host-alive
notification_interval 60
notification_period 24x7
}

aso.....

define service{
use generic-service
host_name VMWARE6
service_description Host Alive
check_command check-host-alive
}


Now I would like monitor the hardware of my ESXI/HOSTS. I have already the Nagios Plugin and "Monitoring Plugin: check_esxi_hardware.py" and python-pywhem installed. How should I configure this ? Below you see what I already have:

# my example

# 'check_esxi_hardware' command definition
define command{
command_name check_esxi_hardware
command_line $USER1$/check_esxi_hardware.py -H $HOSTADDRESS$ -U $ARG1$ -P $ARG2$ -V $ARG3$
}


Do I have to configure a group definition for those meaning esx6,esx7,esx8,esx9 and a serrcvice definition for those ? I mean - they use the same ip.

Could any tell me how this works. We use Fujitsu Simens RX2540M1 Sercver for our VMWare.

Please see my attachments.

Hi @michaelpn,

You can just do the same thing you did earlier. Just put them in a host-group as ESXI servers.

If they are using the same IP address is also fine.

Here is another interesting thing you can do to create those host,service definitions if you want to save time. Use object inheritance.

Take a look at this Object inheritance

Also,if you are using plugin to monitor ESXI servers make sure the ports are open.

Let us know if you have any questions.

Hi dwasswa,

It works fine with the ESXI hosts and I get all 4 up on on the site but I still have a small issue. I get this warning from ESX6 Host where I have created this service:

# my example warning from Nagios Services

This is my commands.cfg file:

# 'check_esxi_hardware' command definition
define command{
command_name check_esxi_hardware
command_line $USER1$/check_esxi_hardware.py -H xxx.xx.x.xx -U root $ARG1$ -P 'xxxxxxxx' $ARG2$ -CV FujitsuSiemens $ARG3$

# my qustions for you:

1: why this warning ?

2: what do I have to change ?


Please attachment:)

You mad some errors in: Please change: to: since you already defined the command.

Also,lets make sure the command works;please test it on your remote host(ESXI server) locally by:

Go to your ESXI sever in: Run your command:

Hi dwasswa,

Know I have solved the challenge with this statement:

# 'check_esxi_hardware' command definition
define command{
command_name check_esxi_hardware.py
command_line $USER1$/check_esxi_hardware.py -H 172.31.1.12 -U root $ARG1$ -P 'xperd4zzz' $ARG2$ -C 5989 $ARG3$
}

define service{
use generic-service
host_name ESX6
service_description ESX Hardware Check
check_command check_esxi_hardware.py
}
I get this from:

Current Status:
OK
(for 0d 0h 34m 52s)
Status Information: OK - Server: FUJITSU PRIMERGY RX2540 M1 s/n: YLVT016881 System BIOS: V5.0.0.9 R1.31.0 for D3289-A1x 2017-01-20

Question:

1: how should I add the others ?

Hi @michaelpn,

By others do you mean hosts ESX7,ESX8,ESX9 or you mean services.

Hi dwassawa,

I mean define command:

# 'check_esxi_hardware' command definition
define command{
command_name check_esxi_hardware.py
command_line $USER1$/check_esxi_hardware.py -H xxx.xx.x.xx -U root $ARG1$ -P 'xxxxxxx' $ARG2$ -C 5989 $ARG3$
}

If you look at IP-adress it is for esx6. What about 7,8,9 how do I add them? Do I add the ip behinds the -H or how ?

If I add the # 'check_esxi_hardware' command definition twice in the command.cfg with the IP from ESX7 behind the -H xxx.xx.x.xx file I get this failure:

# my example

Website: https://www.nagios.org
Reading configuration data...
Read main config file okay...
Warning: Duplicate definition found for command 'check_esxi_hardware.py' (config file '/usr/local/nagios/etc/objects/commands.cfg', starting on line 134)
Error: Could not add object property in file '/usr/local/nagios/etc/objects/commands.cfg' on line 135.
Error processing object config files!


# my example END

If I add the IP from ESX7 and add it to the # 'check_esxi_hardware' command definition behind the -H xxx.xx.x.xx I get this failure:

# my example

[10-10-2017 10:58:35] SERVICE ALERT: ESX7;ESX Hardware Check;WARNING;SOFT;2;(No output on stdout) stderr: Traceback (most recent call last):

... and I get this for both ESX6 and ESX7..... But if I delete the IP for ESX7 it turns green again for ESX6. Of course I remember to add ESX7 in the hostgroups.cfg file regarding the above example but it doesn’t not help!!

# my example END

What do I wrong ?

Hi, I have solved myself

Glad to hear this is resolved.
