Use the following script to reach Grafana API by IP with username and password.
Note: values in this script are only an example. Before running this script on your machine, first update grafana_host, grafana_port, grafana_username, grafana_password, and datasource_name with your own actual values.

Code Block

language	bash

#!/bin/bash

#Get a single data source by name
#GET /api/datasources/name/:name

grafana_host=10.2.7.243100
grafana_port=80
grafana_username='admin'
grafana_password='promadminz-operatorpassword'
datasource_name='hivemq-2021metrics-metr1'

curl --location \
  --header 'Content-Type: application/json' \
  --header 'Accept: application/json' \
  "http://${grafana_username}:${grafana_password}@${grafana_host}:${grafana_port}/api/datasources/name/${datasource_name}"

Use the id value as Datasource id.

If all credentials are valid, the output of the script is JSON like this:

Code Block

language	json

{
  "id": 52,
  "uid": "bbEC2jv4k",
  "orgId": 1,
  "name": "hivemq-2021metrics-metr1",
  "type": "prometheus",
  "typeLogoUrl": "",
  "access": "proxy",
  "url": "http://vmihivemq-metrics-20211-victoria-metrics-single-server.hivemq-2021metrics-metr1.svc.cluster.local:8428",
  "password": "",
  "user": "",

  "basicAuthPassword": "",
  "withCredentials": false,
  "isDefault": false,
  "jsonData": {},
  "secureJsonFields": {},
  "version": 1,
  "readOnly": false
}
