Add multiple groups in Bulk

[emartine]

I am in the process of creating groups for multiple systems that will be added into nagios and I would like to have host groups in place. There will be a total of 51 groups that I will be adding. Is there a way to add multiple groups instead of one by one?

The easiest way would be for you to create a file called hostgroups.cfg and put it in /usr/local/nagios/etc/import and then run these commands:

Code: Select all

cd /usr/local/nagiosxi/scripts
./reconfigure_nagios.sh

That will import the config file to the CCM and apply configuration.

Here is an example of the layout:

Code: Select all

define hostgroup {
    hostgroup_name    linux-servers
    alias             Linux Servers
    members           localhost
}

define hostgroup {
    hostgroup_name    anotherhostgroup
    alias             Another Hostgroup
    members           localhost
}

define hostgroup {
    hostgroup_name    anotherhostgroup2
    alias             Another Hostgroup2
}

You don't have to define the members (only the hostgroup_name and alias are required), you can see here for other available options you can specify for them:

https://assets.nagios.com/downloads/nag ... #hostgroup

You could also use the API to do this, please go to http://YOURXISERVER/nagiosxi/help/api-c ... -hostgroup for an example.

Let us know if you have any questions.

To script it through the API you would have to do something like the following

Code: Select all

#!/bin/bash

declare -a hostgroup=("hostgroup 1" "hostgroup 2" "hostgroup 3")
declare -a alias=("hostgroup 1 alias" "hostgroup 2 alias" "hostgroup 3 alias")


num=0
for i in "${hostgroup[@]}"
do
    al="${alias[$num]}"
    data=`echo "hostgroup_name=$i&alias=$al"`
    curl -XPOST "http://YOUR_HOST/nagiosxi/api/v1/config/hostgroup?apikey=YOUR_API_KEY&pretty=1" -d "$data"
    num=$((num+1))
done
curl -XPOST "http://YOUR_HOST/nagiosxi/api/v1/system/applyconfig?apikey=YOUR_API_KEY"

Thank you Scott much appreciate it. We recently upgraded to Nagios 5.5.7 and I attempted to use the Bulk host monitoring wizard to add a set of servers but I am getting a configuration error.

Can I send you a PM?

[scottwilkerson]

After consulting with the developers about the cause of this, we did come up with a cause and that is the file format changes slightly in the newer versions and need to be re-written to be parsed correctly.

Lets to the following. Remove the erroneous configs for the host/services, in the CCM.

Then

CCM -> Tools -> Config File Management
Delete Files
Write Configs
Verify Files
Restart Nagios Core

This will reset the configs

Now, the Bulk Host Import Wizard should work correctly.

Verification gave me an error

Error: Service description, host name, or check command is NULL
Error: Could not register service (config file '/usr/local/nagios/etc/services/<Aservername>.cfg', starting on line 16)

***> One or more problems was encountered while processing the config files...

Check your configuration file(s) to ensure that they contain valid
directives and data definitions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.





I replaced the name of the server with <Aservername>

I'll try the wizard in a few. I removed the hosts that were causing the issue using CCM and after applying the Configuration applied successfully page only shows this (see below) and get cut off not sure if that was in part due to the upgrade or something else. Though I am sure that the pre-flight check is fine it would be nice to see the entire output.

In the web UI you have to click verify to see the whole output.

Let us know if you have problems with the bulk wizard after running this procedure

The bulk modification wizard works now



I tried the import via the command line and it seemed to have worked. Any idea what the php warning might be about?
