API Post assistance.

I am trying to convert an ols script from Zabbix 1.8 to 2.X and am having some trouble.

The command below works on 1.8, but generated an error on 2.0.2
Note that the $AUTH_TOKEN has been populated in both cases ensuring this is not an authentication issue.

API='http://#.#.#.#/zabbix/api_jsonrpc.php'
curl -i -X POST -H 'Content-Type: application/json-rpc' -d "{\"params\": {\"output\": \"extend\", \"sortfield\": \"name\"}, \"jsonrpc\": \"2.0\", \"method\": \"hostgroup.get\",\"auth\": \"$AUTH_TOKEN\", \"id\": 0}" $API

The error it returns on 2.0.2

HTTP/1.1 200 OK
Date: Mon, 12 Nov 2012 20:09:35 GMT
Server: Apache/2.2.22 (Ubuntu)
X-Powered-By: PHP/5.3.10-1ubuntu3.4

Content-Type: application/json

{"jsonrpc":"2.0","error":{"code":-32700,"message":"Parse error","data":"Invalid JSON. An error occurred on the server while parsing the JSON text."},"id":null}

Anyone have any ideas what's missing?

That's strange, it works fine when I try it. Are you sure the authentication token is correct?

curl -i -X POST -H 'Content-Type: application/json-rpc' -d "{\"params\": {\"output\": \"extend\", \"sortfield\": \"name\"}, \"jsonrpc\": \"2.0\", \"method\": \"hostgroup.get\",\"auth\": \"5c16ae15d4a3747d2488fcd4fc66b9c3\", \"id\": 0}" http://localhost/zabbix/trunk-public/frontends/php/api_jsonrpc.php

Positive.

Originally, the script failed to capture the token and I had to modify it. Looks like the response from a 2.0.2 and a 1.8 server are different. See below

From these examples you can see that there a number of differences. Mainly the absence of the "Set-Cookie: zbx_sessionid=" lines. Because of this, I had to update my script and change how to parsed out the authentication token. However in the end I am positive I am getting the correct token.
For reference I am using the following command to parse the token from both 1.8 and 2.0.2 servers.

curl -i -X POST -H 'Content-Type: application/json-rpc' -d "{\"params\": {\"password\": \"$ZABBIX_PASS\", \"user\": \"$ZABBIX_USER\"}, \"jsonrpc\": \"2.0\", \"method\": \"user.authenticate\",\"auth\": \"\", \"id\": 0}" $API | awk -F \" '{print $8 }'

I can not recall where I found the script I am using, but I will include it here so you can see what I am working with.

(NOTE: This has been modified from the Authors original script.)

So I took another approach and employed a python script to see if I could make any headway. I am still not any closer, but it is now even more apparent that there is a significant change in the API. I did a host get on both the 1.8 and the 2.0 server and here are the results respectively.

1.8

Traceback (most recent call last):

In this case the new API only returns the hostid instead of the full host record.

So it looks like I have a little more digging to do before I get this figured out...

Anyone have any thoughts?

Yes, there are quite a few differences between the 1.8 and 2.0 APIs. One of them is that the "extendoutput" parameter is no longer supported in 2.0. You can use either "output": "extend" or pass an array of property names that you need.

Refer to the 2.0 manual for more details

I was afraid of that. Looks like I am stuck manually updating zabbix for now. I am no programmer and having looked at the scripts for hours, I still have no idea on exactly what to change to make it work.. Hopefully someone will eventually have a few working examples I can work from sometime in the future.

Thank you for your input.
