How to dedicate hostgroup to user in Nagios core

nagios

I want to create some user accounts, each user has its own hostgroup. When they login to their account, they can only view and manage the hosts in their group. How do I do this? Is there a tool to easily mange? I am new to Nagios. Thank you.

define a contact

define contact{
    contact_name                    somedude
    alias                           somedude
    service_notification_period     24x7
    host_notification_period        24x7
    service_notification_options    w,u,c,r
    host_notification_options       d,r
    service_notification_commands   notify-service-by-email
    host_notification_commands      notify-host-by-email
    email                           somedude@example.org
}

define a group containing the contact

define contactgroup {
    contactgroup_name       somegroup
    members                 somedude
}

when you define a host, include the contact_group

define host {
    host_name       someserver.example.org
    contact_groups  somegroup
    address         1.2.3.4
    use             generic-host
    notifications_enabled           1
}

create a password for this user:

htpasswd /etc/nagios3/htpasswd.users somedude

(/etc/nagios3 might not be the right directory depending on your install)

Nagios 3 config ideas

I recently divided files by business area, then into staging/production, but that required too much prior knowledge from other colleagues to just find something and change it. Also we moved some servers around and I realised it would be useful to have config-per-host files that could be moved as well. Also, having config-per-host allows you to neatly encapsulate all the monitoring for a particular host (or hostgroup) in one file, and see easily what you are doing for that host. On top of that we have a central commands.cfg file, divided up by each business area which can be easily searched.

However none of this is truly satisfactory - using flat-file storage for configuration commits you to favouring one particular ordering method over another. This sort of configuration really benefits from the relational model. Most new monitoring products have implemented configuration from a database for this reason, I guess.

Currently NDOUtils (warning: pdf) gets your config and event data into a database, but as far as I know there's no way to tell Nagios to use that database as config source. It does give you the opportunity to create tables aside from those required by NDOUtils, perhaps creating a separate nagios_config database where you can map things out and then script up a solution that pulls this information out of the database and creates your config.

I'm going to try and use Puppet to generate my Nagios configs in the near future, hopefully it will let me resolve these sorts of issues.

Nagios best practices for setting up hosts/services

I think the answer to your question is not definitive, but will reveal itself over time as you develop a deeper understanding of how Nagios works. Services are generally tied directly to the host they run on, but as you are discovering, that is just a convention. A convention that works and provides some shortcuts, mind you, but a convention, nonetheless.

Also know that that you can define any check as the host check. It does not need to be ping. Perhaps check_http is better for your use.
See the image and host definition I use to check internet connectivity

define host{
use         generic-host,host-pnp       ; Name of host template to use
host_name       www.microsoft.com
alias           www.microsoft.com
address         www.microsoft.com
check_command       check_http
.
.
.
}

Given what you've said, I would create a dummy service with a bunch of you third party services tied to it for now and adjust it as you see fit.

To address your 3rd question, if you go the route of a host per service, you could use a host or service group to group them for display.
