Here's what makes Grafana so compelling:
- It makes it easy to build beautiful graphs and set up alerts.
- It works out of the box with InfluxDB.
- It works very well in a containerized environment like Aptible.
Here's how you can deploy Grafana on Aptible:
Grafana needs a database to store sessions and Dashboard definitions. It works great with PostgreSQL, which you can deploy on Aptible. The rest of this tutorial assumes that you provisioned a PostgreSQL Database and have access to its credentials.
Once you created the PostgreSQL Database, create a tunnel using the
aptible db:tunnel command, then connect using
psql and run the following commands to create a
sessions database for use by Grafana:
CREATE DATABASE sessions;
Then, connect to the newly-created
And, finally, create a table for Grafana to store sessions in:
CREATE TABLE session ( key CHAR(16) NOT NULL, data BYTEA, expiry INTEGER NOT NULL, PRIMARY KEY (key) );
Grafana is available as a Docker image and can be configured using environment variables. As a result, you can use Direct Docker Image Deploy to easily deploy Grafana on Aptible.
Here's a minimal deployment configuration to get you started. In the example below, you'll have to substitute a number of variables:
$ADMIN_PASSWORD: Generate a strong password for your Grafana
$SECRET_KEY: Generate a random string (40 characters will do).
$YOUR_DOMAIN: The domain name you intend to use to connect to Grafana (e.g.
$DB_USERNAME: The username for your PostgreSQL Database. For a PostgreSQL Database on Aptible, this will be
$DB_PASSWORD: The password for your PostgreSQL Database.
$DB_HOST: The host for your PostgreSQL Database.
$DB_PORT: The port for your PostgreSQL Database.
aptible apps:create grafana aptible deploy --app grafana --docker-image grafana/grafana \ "GF_SECURITY_ADMIN_PASSWORD=$ADMIN_PASSWORD" \ "GF_SECURITY_SECRET_KEY=$SECRET_KEY" \ "GF_DEFAULT_INSTANCE_NAME=aptible" \ "GF_SERVER_ROOT_URL=https://$YOUR_DOMAIN" \ "GF_SESSION_PROVIDER=postgres" \ "GF_SESSION_PROVIDER_CONFIG=user=$DB_USERNAME password=$DB_PASSWORD host=$DB_HOST port=$DB_PORT dbname=sessions sslmode=require" \ "GF_LOG_MODE=console" \ "GF_DATABASE_TYPE=postgres" \ "GF_DATABASE_HOST=$DB_HOST:$DB_PORT" \ "GF_DATABASE_NAME=db" \ "GF_DATABASE_USER=$DB_USERNAME" \ "GF_DATABASE_PASSWORD=$DB_PASSWORD" \ "GF_DATABASE_SSL_MODE=require" \ "FORCE_SSL=true"
There are a lot more configuration options available in Grafana. Review Grafana's configuration documentation for more information.
Finally, follow the How do I expose my web app on the Internet? tutorial to expose your Grafana app over the internet.
Make sure to use the same domain you configured Grafana with (
$YOUR_DOMAIN in the example above)!
Once you've exposed Grafana, you can navigate to
$YOUR_DOMAIN to access Grafana. Connect using the username
admin and the password you configured above (
Once logged in to Grafana, you can connect Grafana to an InfluxDB Database by creating a new data source. To do so, click the Grafana icon in the top left, then navigate to data sources and click "Add data source".
The following assumes you have provisioned an InfluxDB Database. You'll need to interpolate the following values
$INFLUXDB_HOST: The hostname for your InfluxDB Database. This is of the form
$INFLUXDB_PORT: The port for your InfluxDB Database.
$INFLUXDB_USERNAME: The username for your InfluxDB Database. Typically
$INFLUXDB_PASSWORD: The password.
These parameters are represented by the connection URL for your InfluxDB database in the Aptible Dashboard and CLI. For example, if your connection URL is
https://foo:[email protected]:456, then the parameters are:
Once you have those parameters, in Grafana, use the following configuration for your data source:
- Name: Any name of your choosing. This will be used to reference this data source in the Grafana Web UI.
- Type: InfluxDB
- HTTP settings: - URL:
https://$INFLUXDB_HOST:$INFLUXDB_PORT. - Access:
- HTTP Auth: Leave everything unchecked
- Skip TLS Verification: Do not select
- InfluxDB Details: - Database: If you provisioned this InfluxDB Database on Aptible and / or are using it for a InfluxDB Database Metric Drain, set this to
db. Otherwise, use the database of your choice. - User:
Finally, save your changes.
If you are using an InfluxDB Metric Drain, consider reviewing Suggested Queries.
Once you've added your first data source, you might also want to consider following Grafana's getting started documentation to familiarize yourself with Grafana.
If you get an error connecting, use the
aptible logscommands to troubleshoot.
That said, an error logging in is very likely due to not properly creating the
sessionsdatabase and the
sessiontable in it as indicated in Configuring the Database.
