Find hosts with multiple parents, track changes

Hi,

What would be the recommended way to locate hosts with multiple parents set?
SQL query, or is there perhaps a report?

Also, is there a report (or SQL query) we can run that shows recent configuration changes (last 24h)?
With several admins making changes, it would be very useful to be able to see this.

Thanks,

Otto

Hi @ottow,

You can use the API to retrieve this information. For example, the following API command will return the the configuration stored in the database for a host.

Code: Select all

curl -XGET "https://192.168.23.112/nagiosxi/api/v1/config/host?apikey=<theapikey>&host_name=localhost&pretty=1" 
It will return json data. You can view documentation and sample commands by going to Help > API Docs > Config Reference.
{
"host_name": "localhost",
"use": [
"linux-server"
],
"alias": "localhost",
"address": "127.0.0.1",
"parents": [
"192.168.23.140",
"192.168.23.142"
],
"register": "1"
}
The audit log will provide information about changes made in the Core Configuration Manager. Go to Admin > System Information > Audit Log. We have made quite a few improvements to this log, so if you're running an old version it may not be as detailed.

Let me know if you have more questions.

Hi,

The API call will return the data for 1 host, which is not what I am looking for.
I want to list all hosts in the system with multiple parents, presumably this needs a SQL query which I would like assistance formulating.

I'll look into the Audit Log, thanks for the info.

What he recommended should work.

You can do this:
- Change YOURXISERVER and YOURAPIKEY

Code: Select all

yum install jq -y
curl -XGET -k -L --silent "http://YOURXISERVER/nagiosxi/api/v1/config/host?apikey=YOURAPIKEY&pretty=1" -k -L | jq -r '.[] | .host_name, .parents'
Or go here and look (or copy paste into excel):

Code: Select all

http://YOURXISERVER/nagios/cgi-bin/config.cgi?type=hosts
Thank you!

The above just produces an error:
jq: error: Cannot index string with string
jq: error: Cannot index string with string

Can I please have a SQL query instead

Please PM the output of this command to make sure it works first:

Code: Select all

curl -XGET -k -L --silent -vvv "http://YOURXISERVER/nagiosxi/api/v1/config/host?apikey=YOURAPIKEY&pretty=1"

API access had been disabled for some reason for the user I was testing with.
This works now, but is still less convenient and much less readable than a SQL query output.
Ref https://support.nagios.com/forum/viewto ... 16&t=59669 for what I am looking for.

I can understand that is is less convenient, but as the author of the other comment, I want to chime in that not all items can be referenced from a single query like I posted in the other thread.
