Click the ‘+’ button to add a new connection.

2. Connecting InfluxDB with VS Code

Now, we will connect the InfluxDB in VS Code. Click the ‘+’ button or by using the command palette (Ctrl + Shift + p) and then click the Add new connection.

Add new connection

Now select the connection and then add the InfluxDB token and then click the Test connection to check the connection.

Test Connection

Once the connection is successful you could see the buckets and measurements that are available in the given organization like below

3. Writing Flux Query in VS Code

Now, will write the Flux query to check whether we can get the data from InfluxDB.

Create a new file in VS Code Editor with extension as .flux and write your flux query.

from(bucket: "systemmetric")
|> range(start: -1h, stop: now())
|> filter(fn: (r) => r["_measurement"] == "cpu")
|> filter(fn: (r) => r["cpu"] == "cpu-total")
|> filter(fn: (r) => r["_field"] == "usage_user")
|> aggregateWindow(every: 1h, fn: mean, createEmpty: false)
|> yield(name: "mean")

Now run the flux query using the command Ctrl + Alt + E. Now you could see the result like below.
