Align defaults for datasource settings

[BenediktSeidl]

Previously we had two different defaults for the edition setting:

• one default was set to CEE but was only applied if the datasource settings page was opened and was only applied to the backend after "save" was pressed.
• the other default setting was set to RAW and was applied in the backend

If you use a provisioned datasource and did not specify the edition explicitly, you saw "CEE" chosen in the UI, but the backend actually used the "RAW" edition.

In order to align this, we chose to set both defaults to CEE.

If you use checkmk raw edition and a provisioned datasource or created the datasource with an very old version of this plugin you have to take manual action:

• if you use a provisioned datasource: specify the edition explicitly
• if you used a old version of this plugin to create the datasource: open the datasource settings, make sure the RAW edition is chosen, and save the settings.

You can use the following python script to check if you are affected: (You can only be affected if you use the plugin to fetch matrices from checkmk raw edition.)

import requests

GRAFANA_URL = "http://127.0.0.1:3000/"  # with closing slash

URL = f"{GRAFANA_URL}api/datasources"

GRAFANA_USER = "admin"
GRAFANA_PASSWORD = "password"
data_sources = requests.get(URL, auth=(GRAFANA_USER, GRAFANA_PASSWORD))

for data_source in data_sources.json():
    if data_source["type"] in {"tribe-29-checkmk-datasource", "checkmk-cloud-datasource"}:
        json_data = data_source["jsonData"]
        if "edition" not in json_data:
            print("found affected data_source:")
            print(f'  name: {data_source["name"]}')
            print(f'  id: {data_source["id"]}')
            print(f'  uid: {data_source["uid"]}')
