I want to add registered hosts as elements in map using zabbix API

[zuzuzu]

We are developing a script to reflect registered hosts in the map using the zabbix API as described in the title.

I coded it in python referring to the documentation, but the message *“Host added to map with ID:

{result[‘sysmapids’][0]}
”* which is displayed when a correct API response is returned, is displayed, but the host is not added to the map.

I am trying to add an element using the map.update method. Or should I use another method to add the element?

Here is the python code.

import requests
import json

class ZabbixAPI:
  def __init__(self, url, token):
    self.url = url
    self.token = token
    self.registered_hosts = set() # 既に登録されたホストのIDを追跡するセット

  def get_host_info(self):
    headers = {
      'Content-Type': 'application/json-rpc'
    }

    data = {
      'jsonrpc': '2.0',
      'method': 'host.get',
      'params': {
        'output': 'extend'
      },
      'id': 1,
      'auth': self.token
    }

    response = requests.post(self.url, data=json.dumps(data), headers=headers, verify=False)

    if response.status_code == 200:
      return response.json()['result']
    else:
      print(f"Error: {response.status_code}")

  def add_host_to_map(self, map_id):
    # ホストIDを取得
    hosts = self.get_host_info()
    if hosts:
      for host in hosts:
        host_id = host['hostid']
        if host_id not in self.registered_hosts:
          # マップにホストを追加
          self.update_map_with_host(map_id, host_id)
          self.registered_hosts.add(host_id)
        else:
          print(f"Host with ID {host_id} is already registered.")
    else:
      print("No hosts found.")

  def update_map_with_host(self, map_id, host_id):
    headers = {
      'Content-Type': 'application/json-rpc'
    }

    data = {
      'jsonrpc': '2.0',
      'method': 'map.update',
      'params': {
        'sysmapid': map_id,
        'elements': [
          {
            'elementtype':0,  # ホストを表す要素
            'elementid': host_id, # ホストのID
            'iconid_off': 2,  # ホストのアイコン (オフ) のID
          }
        ]
      },
      'auth': self.token,
      'id': 1
    }

    response = requests.post(self.url, data=json.dumps(data), headers=headers, verify=False)

    if response.status_code == 200:
      result = response.json().get('result')
      if result and result['sysmapids']:
        print(f"Host added to map with ID: {result['sysmapids'][0]}")
      else:
        print("Error updating map with host.")
    else:
      print(f"Error: {response.status_code}")

  def generate_random_coordinate(self, min_value=0, max_value=500):
    import random
    return random.randint(min_value, max_value)

if __name__ == "__main__":
  # Zabbix サーバーの URL
  url = 'http://127.0.0.1/zabbix/api_jsonrpc.php'
  # Zabbix API での認証トークン
  token = ''
  # 追加するホストのマップID
  map_id = '5'

  zabbix_api = ZabbixAPI(url, token)
  zabbix_api.add_host_to_map(map_id)​
