Nagios Support Forum

Hello,

We need to access the back end. I have been looking at services provided by the Backend API URL plugin, but we need more finely-grained queries than appear to be provided.

For example, we need to be able to query the current host status, returning only those with a certain command:

http://nagiosxi/nagiosxi/backend/?cmd=g ... _host_ping[/b]

Does this plugin offer a way to do that that I may have missed? Failing that, what is the best away to achieve this functionality?

Thanks,
Dhruva

Currently we don't have a feature like this built into the API of XI. I know some users have actually written their own, but if that's not an option you can post it as a feature request on tracker.nagios.com.

Hello,
I would also need to make more fine-grained queries to the back-end. Say we're monitoring 50,000 servers and I need the status of only a single one at a time. Getting the humongous xml would not be the best way I guess...

I know some users have actually written their own...

What would be the way (flow) to write such functionality?

Thank you!

In the newest version of the backend API (with XI 2011R2.1) you can add filters to the URL string on some calls.

For example, on a gethost status call, you can add &host_id=12345 to the url and only get info on that item.
you can also use &host_name=MYHOST

For example, this will only give you the status of a host with a host_name

That's great! Thanks for the info! But where can I see the API's documentation with a list of possible queries?
The API Component I installed a couple of days ago by default does not offer such info in its settings.

Cheers!

Unfortunately, we don't have documentation on this yet, it is currently an undocumented/unadvertised feature but it is on the TODO list.
