Please do not bump threads, especially after only 18 minutes. You will just push yourself to the bottom of our queue.

There is a hostgroup.cfg file in the directory you specified already. Please look at this file for information on setting up a hostgroup -
https://assets.nagios.com/downloads/nag ... #hostgroup

It may be in your /usr/local/nagios/etc/objects/ folder as well which I see you have.

Hi,

no i dont have.

what you see is what i have created by myself--> it is not correct.

As you see i dont have this file, maybe i removed him by mistake.

The question is how can i created hostgroup.cfg again?

You can create hostgroup.cfg your own by using vi, vim, or nano. Then just enter the definition you want to apply as stated in the documentation page I linked you -

Hi,

Basically what I want to add is that on dashboard under current status  Host groups I will be able to see all my servers grouped the same as I see localhost (please see the attached screenshot )

So I have few quires about this:

1) Why I see only local host?
2) On which file I need to configure to see it in dashboard  current status  Host groups ?

You need to modify the file that contains the hostgroup to add other members. This depends how you setup your directory structure. Assuming it's standard, what is the output of the following?
