Test the connection

Now that you’ve configured the connection details, save the data source and verify that Grafana can successfully connect to your InfluxDB instance.

Query language	Success message
Flux	`datasource is working. X buckets found`
InfluxQL	`datasource is working. X measurements found`
SQL	`OK`

Symptom	Likely cause	Solution
Connection refused	InfluxDB not running or wrong URL	Verify the URL and that InfluxDB is accepting connections on the specified port
Unauthorized (401)	Invalid API token or credentials	Generate a new token with read access, or verify your username and password
Organization not found	Incorrect organization name (Flux)	Check the organization name in your InfluxDB UI under Settings
Bucket not found	Incorrect bucket name or token lacks access (Flux)	Verify the bucket name and that the token has read permission for it
Database not found	Incorrect database name (InfluxQL/SQL)	Verify the database name in your InfluxDB instance

In the next milestone, you’ll run a query and explore your InfluxDB data in Grafana.
