Zabbix HTTP Agent API request from my zabbix server - need another set of eyes.​

[[email protected]]

I am trying to get the Zabbix HTTP Agent item configured to pull API data from my Zabbix server through my proxy.

1. I have written a script in python to use the Zabbix API and it returns the expected data. Along with a json formatted response this is the script output "Number of problems with tags 'device=camera' and 'status=offline' and 'technician=belair': 22"

import requests
import json
# Replace with your Zabbix server URL and credentials
zabbix_url = "http://myserver.yisd.net/zabbix/api_jsonrpc.php"
api_token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxx xxxxxxxxxxxxxxx"
# Headers for the request
headers = {
'Content-Type': 'application/json-rpc',
'Authorization': f'Bearer {api_token}'
}
# Data for the request
data = {
'jsonrpc': '2.0',
'method': 'problem.get',
'params': {
'output': 'extend',
'selectTags': 'extend',
'tags': [
{'tag': 'status', 'value': 'offline'},
{'tag': 'technician', 'value': 'delvalle'},
{'tag': 'device', 'value': 'camera'}
]
},
'id': 1
}
# Send the request
response = requests.post(zabbix_url, headers=headers, json=data)
# Check for errors
if response.status_code != 200:
print(f"Error: {response.status_code}")
# print(response.json())
else:
response_json = response.json()
if 'error' in response_json:
print(f"API Error: {response_json['error']}")
else:
problems = response_json.get('result', [])
print(f"Number of problems with tags 'status=offline' and 'technician=belair': {len(problems)}")
# print(response.json())

2. However if I take the same json response body from my python script and use it for my HTTP Agent item it only returns this result {}. Here is my complete json response body being used

{
"jsonrpc": "2.0",
"method": "problem.get",
"params": {
"output": "extend",
"countOutput": "true",
"selectTags": "extend",
"tags": [
{"tag": "status", "value": "offline"},
{"tag": "technician", "value": "delvalle"},
{"tag": "device", "value": "camera"}
]
}
}

This is the result using the HTTP Agent item test button




3. I have tried performing an API request using curl for something very basic and for my failing json request body on the same proxy server

This curl version of my request returns an error

curl --header "Content-Type: application/json" --request POST --data '{ "jsonrpc": "2.0", "method": "problem.get", "params": { "username": "zabbixapi_ro", "password": "xxxxxxxxxxxxxx", "output": "extend", "countOutput": "true", "selectTags": "extend", "tags": [{"tag": "status", "value": "offline"}, "tag": "technician", "value": "delvalle"},{"tag": "device", "value": "camera"}]},"id":1}' "http://zabbix1.yisd.net/zabbix/api_jsonrpc.php"

Returns this error
{"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}

This curl command on my proxy returns the expected result

curl --header "Content-Type: application/json" --request POST --data '{"jsonrpc": "2.0", "method": "user.login", "params": {"username": "zabbixapi_ro", "password": "xxxxxxxxxxxxxxx"}, "id": 1}' "http://myserver.yisd.net/zabbix/api_jsonrpc.php"

Good Result
{"jsonrpc":"2.0","result":"xxxxxxxxxxxxxxxxxxxx xxx xxxxxxxxx","id":1}zabbix@zabbixproxy2

This has led me to believe that I am missing some configuration requirement in the HTTP Agent configuration page. I have tried every possible variation from documentation and so at this point I am hoping just another set of eyes will be helpful.

If i understand right, your result would be "22", right? So, try change Type of information from Texto to Numeric

Correct answer should be 22. If I change the type of information field to "Numeric (unsigned)" or "Numeric (float)" I get this after the test.

If I change the "Retrieve Mode" in the HTTP Agent GUI to "Body and Headers" I get all the header values but still no body values

All of the Zabbix examples\documentation seems to contains"id": 1 line in their json request body examples

I have noticed that this json request body with the line "id": 1
{
"jsonrpc": "2.0",
"method": "problem.get",
"params": {
"output": "extend",
"countOutput": "true",
"selectTags": "extend",
"tags": [
{"tag": "status", "value": "offline"},
{"tag": "technician", "value": "delvalle"},
{"tag": "device", "value": "camera"}
]
},
"id": 1
}

Gives me this error
{"body":{"jsonrpc":"2.0","error":{"code":-32602,"message":"Invalid params.","data":"Not authorized."},"id":1}}

....but this json request body without "id": 1
{
"jsonrpc": "2.0",
"method": "problem.get",
"params": {
"output": "extend",
"countOutput": "true",
"selectTags": "extend",
"tags": [
{"tag": "status", "value": "offline"},
{"tag": "technician", "value": "delvalle"},
{"tag": "device", "value": "camera"}
]
}
}

Gives me this result
{}

What I don't get is why you set Basic HTTP auth, when you already connect with a bearer token?
I would first broaden the request and not sure but if you filter with tags you also must specify how you filter, exist, doesn't exist, equals, doesn't equals etc.
You are now missing the operator.
In your first post in section 3: "tags": [{"tag": "status", "value": "offline"}, "tag": "technician", "value": "delvalle"},{"tag": "device", "value": "camera"}]}
The second tag is invalid json. (missing opening { )
Take a look at https://www.zabbix.com/documentation...ce/problem/get on how to work with the API

That Basic HTTP auth was just over configuring as a result of trying tooooo many combinations. I have taken out the Authorization Bearer portion and left the Basic HTTP auth option. I have corrected the "{" issue with the tag. What is the most basic request body I could put in just enough to test the other settings to verify that they are working. Right now I am thinking there is something wrong in my request body that filters out all my data, even though the same request body works fine in my python script.

I had not noticied the operator option before, odd that none of the examples utilize it. I reworked the response body with the operator option but still only get {} as a response.

Here is my new version. I also simplified the tag option to just one tag in case I was over filtering somehow.
{
"jsonrpc": "2.0",
"method": "problem.get",
"params": {
"output": "extend",
"countOutput": "true",
"selectTags": "extend",
"tags": [
{ "tag": "technician", "value": "delvalle", "operator": "4" }
]
}
}

Did you read the link I posted? If so, do you see tags as a parameter?
selectTags is one, tags isn't. selectTags: "Return a tags property with the problem tags. Output format: [{"tag": "<tag>", "value": "<value>"}, ...]."
There is a filter parameter
As it seems you want to filter on a certain technicians name. Maybe your approach should be: get userID > use this user ID and the " Retrieving problems acknowledged by specified user" example.
I don't use this part of the API the example in the manual should be enough.
