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=10.2.7.100
grafana_port=80
grafana_username='admin'
grafana_password='adminz-password'
datasource_name='hivemq-metricsprometheus-1'

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": 5211,
  "uid": "abcdef1hijkabcd1efgh",
  "orgId": 1,
  "name": "hivemq-metricsprometheus-1",
  "type": "prometheus",
  "typeName": "Prometheus",
  "typeLogoUrl": "public/app/plugins/datasource/prometheus/img/prometheus_logo.svg",
  "access": "proxy",
  "url": "http://hivemqprometheus-mykube-hivemq-metrics.my-hivemq-namespace.svc.cluster.local:9399prometheus-prometheus:9090/",
  "password": "",
  "user": "",
  "database": "",
  "basicAuth": false,
  "basicAuthUser": "",
  "basicAuthPassword": "",
  "withCredentials": false,
  "isDefault": falsetrue,
  "jsonData": {},
  "secureJsonFields": {},
  "version": 1,
  "readOnly": falsetrue
}
