Jake,

Tested the 'utils-api.inc.php' patch and did some tests. It effectively starts the 'Apply Configuration', but I do get a warning:
From the CLI of the Reactor server:

Code: Select all

curl -k -XPOST --data "apikey=apikeyblabla&pretty=1" "https://nagiosxiprodserver.domain/nagiosxi/api/v1/system/applyconfig"
{"success":"Apply config command has been sent to the backend."}
Also tested with POST:

Code: Select all

curl -k -POST --data "apikey=apikeyblabla&pretty=1" "https://nagiosxiprodserver.domain/nagiosxi/api/v1/system/applyconfig"
{"success":"Apply config command has been sent to the backend."}
Both seem to work.

What would be the officer problem with this warning?

I still don't get it working with the 'Submit an HTTP request' action from Nagios Reactor.

Could someone let me know what I'm doing wrong here? (What is the difference between POST and XPOST by the way..?)

We will need some time to test this and will get back to you with a possible solution sometime tomorrow morning. Thank you!

Willem, passing "-k" from the command line will work but it is not going to work from the web UI. You could try setting up your command in a script on the Reactor and try running it this way. I am not sure if copying the certs over from the XI machine to Reactor will resolve the issue, but you can give it a try. I am going to try this next.
What is the difference between POST and XPOST by the way..?
X is the command in curl:

Code: Select all

curl -X POST
curl -XPOST

Ludmill, the problem is I need to specify the -k option, as we still have a SHA1 cert in our chain. it is however being replaced between now and the end of December. I will test again after my Christmas holiday, as I won't ened to specify the -k option anymore then. Grtz

Willem, give us some feedback after you test it. REST API works with XPOST for me but only if I don't use SSL. Passing "-k" didn't work for me. Using a script in reactor didn't prove to be successful, either. I will do some more digging into this. I will be keeping this thread open.

ludmill,

I can't even get it to work with http.. But imho this should work with https no? How else can we safely submit http requests?

Here's what I have in Reactor:

Code: Select all

Action Type: Submitt an HTTP request
URL: http://192.168.x.x/nagiosxi/api/v1/system/applyconfig/
Request Type: POST
Extra GET/POST Params: apikey=blabla&pretty=1
example01.PNG
I modified a service on my XI box but didn't apply configuration. When I submitted the command from reactor, the configuration got applied. I am not sure why it is not working for you. Try removing the "--data" portion.

Tried removing --data , but I get the same result:

Seems I also can't get it to work anymore with curl from cli:

curl -k -XPOST --data "apikey=blabla&pretty=1" "https://nagiosserver/nagiosxi/api/v1/system/applyconfig"
{"error":"Unknown API endpoint."}

I thought it did work last time I tried. I did update to 5.2.3 in the meantime. Is it possible utils-api.inc.php was updated by the 5.2.3 update?

Were you on 5.2.2 previously on this server?

curl -XPOST --data "apikey=blabla&pretty=1" "http://nagiosserver/nagiosxi/api/v1/system/applyconfig"
Jumping in a bit late, I wonder if this is an apache rewrite rule though. Do you see anything in your error_log or ssl_error_log that pertains to when you run this?
