Adding a new host for monitoring

[ets_user]

Hi,

We would like to write an automated script to add any new hosts to Nagios for monitoring.

This helps when we have huge number of servers to be added at once, takes time if we use Nagios XI.

Could you please let us know if we can do this way, if so how can we ?

Add a host to nagios monitoring by backend in nagios server and not through Nagios XI.
Map the host to the host group by backend in nagios server and not through Nagios XI.


We already have services mapped to hostgroup so it will work from there on.

Thanks.

You can use the API, that's the best method that you can use. See the API section under the Help menu for working examples. See here specifically:

Code: Select all

http://YOURXISERVER/nagiosxi/help/api-config-reference.php#add-host

Or you can manually manage them (they won't be listed in the CCM then):

https://assets.nagios.com/downloads/nag ... ios-XI.pdf

Technically, you can create the configs and then import them as well:

Let us know if you have any questions.

Thanks for the link, it helped us.

We were able to add new host using the command.

Could you please let us know if we can add the host to a particular host group using command line.

We didn't find such thing in the link, though we were able to create host group using command line.

Thanks.

Yes, if using the API you would add the following to the string after -d &hostgroups=YOURHOSTGROUP

In the other scenarios you would add it inside the host define like

Code: Select all

hostgroups               YOURHOSTGROUP

In both cases the hostgroup must previously exist

Hi,

This command is not working.

curl -XPOST "https://10.106.93.70/nagiosxi/api/v1/co ... y&pretty=1" -d "host_name=testapihost1&address=127.0.0.1&hostgroups=Linux_server_VM&check_command=check_ping\!3000,80%\!5000,100%&max_check_attempts=2&check_period=24x7&contacts=nagiosadmin&notification_interval=5&notification_period=24x7&applyconfig=1" -k

It is not adding the host to the hostgroup.

Kindly advise.

Hmm, I just tested this on a 5.7.1 system and it worked as expected. Do you have a host group named Linux_server_VM specifically with underscores and case sensitive?

[ets_user]

Yes we do have it with same name.

But still host is not getting added to the hostgroup.

What version of Nagios XI are you running?

[ets_user]

It is Nagios XI 5.5.6 .

Adding hostgroups and servicegroups was not added until 5.6.0
