Hi,

I have configured nagios server and i want to know how to configure and monitor esxi server on nagios.

Thank you

I suggest using the box293_check_vmware plugin:

https://exchange.nagios.org/directory/P ... re/details

It has a detailed manual, let us know if you need help.

Can you also post the "box293_check_vmware" command definition?

Hi,

Please find below command definition.

define command {
command_name box293_check_vmware
command_line $USER1$/check_by_ssh -E 1 -t 90 -l vi-admin -H 192.168.8.45 -C "nice -n19 ~/box293_check_vmware.pl --server $ARG1$ --check $ARG2$ \"$ARG3$\" \"$ARG4$\" \"$ARG5$\" \"$ARG6$\" \"$ARG7$\" \"$ARG8$\""
}

Hi

I want to define esxi host cpu usage and memory usage service definition. I am using the below steps, but i am getting error for the same. Please guide me how to configure service definition for this.

host cpu:
Command:
box293_check_vmware.pl --check Host_CPU_Usage --server 192.168.1.211 --host 192.168.1.210

Memory:

box293_check_vmware.pl --check Host_Memory_Usage --server 192.168.1.211 --host
192.168.1.210

host cpu:

box293_check_vmware.pl --check Host_CPU_Usage --server 192.168.1.211 --host 192.168.1.210

Memory:

box293_check_vmware.pl --check Host_Memory_Usage --server 192.168.1.211 --host
192.168.1.210

In your vCenter inventory, is the ESX(i) host listed as "192.168.1.210" or by a FQDN like esxihost001.domain.com?

The --host argument requires the actual name of the host object as it appears in the inventory (CaSe sEnSatIve), not it's IP Address ... unless of course it is added to the inventory using the IP Address.

[vinothg]

In my vcenter inventory esxi listed as fqdn only and in my service definition i have configured fqdn only. but i am getting an error. Could you please share with me some sample service definition for esxi host cpu usage check memory usage check.

Thank you.

Is it working from the command line on the vMA?

Code: Select all

~/box293_check_vmware.pl --check Host_CPU_Usage --server vcenter_server_ip_or_fqdn --host esxi_host_ip_or_fqdn

Can you please post the full command and output here so we can see what is going on.

Then if that works, what do you get from your nagios server?

Code: Select all

su nagios
/usr/local/nagios/libexec/check_by_ssh -E 1 -t 90 -l vi-admin -H vma_ip_or_fqdn -C "nice -n19 ~/box293_check_vmware.pl --check Host_CPU_Usage --server vcenter_server_ip_or_fqdn --host esxi_host_ip_or_fqdn"

From the command line i am getting the correct output. Please find the below.

from vma:

OK: Host CPU {Free: 23.2 GHz} {Used: 0.2 GHz} {Total: 23.4 GHz}|'CPU Free'=23.2GHz 'CPU Used'=0.2GHz 'CPU Total'=23.4GHz [Host_CPU_Usage]

from nagios host:

OK: Host CPU {Free: 23.1 GHz} {Used: 0.3 GHz} {Total: 23.4 GHz}|'CPU Free'=23.1GHz 'CPU Used'=0.3GHz 'CPU Total'=23.4GHz [Host_CPU_Usage]
