Retrieving Host Groups and Associated Hosts via Centreon API

Hello,

You can do it with APIv1 but you have to make multiple request

• First you need to authenticate like you did (btw we don’t see your Python script on your post). It will give you a token
• Then you need to list the hostgroups with a request like this (i will use curl for my request, but you can use them to create your Python script) 

  curl --location 'http://CENTREON_ADDRESS/centreon/api/index.php?action=action&object=centreon_clapi' \
  --header 'Content-Type: application/json' \
  --header 'centreon-auth-token: YOUR_AUTH_TOKEN' \
  --data '{
      "action": "show",
      "object": "HG"
  }'

  You will get a JSON like this with all your hostgroups
   

  {
      "result": [
          {
              "id": "1",
              "name": "Infra",
              "alias": "Infra"
          },
          {
              "id": "2",
              "name": "Dev",
              "alias": "Dev"
          }
      ]
  }

   

• With this lists, you will need for each hostgroup to make a “getmember” request

  curl --location 'http://CENTREON_ADDRESS/centreon/api/index.php?action=action&object=centreon_clapi' \
  --header 'Content-Type: application/json' \
  --header 'centreon-auth-token: YOUR_AUTH_TOKEN' \
  --data '{
      "action": "getmember",
      "object": "HG",
      "values": "Infra"
  }'

  You will get the list of the member, like this

  {
      "result": [
          {
              "id": "14",
              "name": "HOST1"
          },
          {
              "id": "13",
              "name": "HOST2"
          }
      ]
  }

This is how you can do it with APIv1, but i think you should take a look with APIv2 method, it’s will be more efficient i think
