To experience the full power of GreptimeCloud, you need to create a service which contains a database with authentication. Open the GreptimeCloud console, signup and login. Then click the
New Service button and config the following:
- Service Name: The name you want to describe your service.
- Description: More information about your service.
- Region: Select the region where the database is located.
- Plan: Select the pricing plan you want to use.
Now create the service and we are ready to write some metrics to it.
If you already have a Prometheus instance running
Add the following section to your Prometheus configuration.
remote_write: - url: https://<host>/v1/prometheus/write?db=<dbname> basic_auth: username: <username> password: <password>
Or if you prefer a fresh start
Spin up a Docker container to write sample data to your database:
docker run --rm -e GREPTIME_URL='https://<host>/v1/prometheus/write?db=<dbname>' -e GREPTIME_USERNAME='<username>' -e GREPTIME_PASSWORD='<password>' --name greptime-node-exporter greptime/node-exporter
After successfully writing data to the service, you can view the data on the GreptimeCloud dashboard. The dashboard provides a variety of visualizations to help you understand, monitor and analyze the data.
Here, we create a panel that displays the 95% CPU usage as an example. To do this, click the
Add Panel button, select a table that contains the CPU usage data, and then choose the
95% aggregation method. Finally, click the
Save button to save the panel. You can now see the new panel and set up an alert rule for it.
