Configuration

The Grafana back-end has a number of configuration options that can be specified in a .ini configuration file or specified using environment variables.

Config file locations

  • Default configuration from $WORKING_DIR/conf/defaults.ini
  • Custom configuration from $WORKING_DIR/conf/custom.ini
  • The custom configuration file path can be overridden using the --config parameter

Note. If you have installed Grafana using the deb or rpm packages, then your configuration file is located at /etc/grafana/grafana.ini. This path is specified in the Grafana init.d script using --config file parameter.

Using environment variables

All options in the configuration file (listed below) can be overridden using environment variables using the syntax:

GF_<SectionName>_<KeyName>

Where the section name is the text within the brackets. Everything should be upper case, . should be replaced by _. For example, given these configuration settings:

[security]
admin_user = admin

[auth.google]
client_secret = 0ldS3cretKey

Then you can override them using:

export GF_SECURITY_ADMIN_USER=true
export GF_AUTH_GOOGLE_CLIENT_SECRET=newS3cretKey

[paths]

data

Path to where Grafana stores the sqlite3 database (if used), file based sessions (if used), and other data. This path is usually specified via command line in the init.d script or the systemd service file.

logs

Path to where Grafana will store logs. This path is usually specified via command line in the init.d script or the systemd service file. It can be overridden in the configuration file or in the default environment variable file.

[server]

http_addr

The IP address to bind to. If empty will bind to all interfaces

http_port

The port to bind to, defaults to 3000. To use port 80 you need to either give the Grafana binary permission for example:

$ sudo setcap 'cap_net_bind_service=+ep' /opt/grafana/current/grafana

Or redirect port 80 to the Grafana port using:

$ sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000

Another way is put a webserver like Nginx or Apache in front of Grafana and have them proxy requests to Grafana.

protocol

http or https

domain

This setting is only used in as a part of the root_url setting (see below). Important if you use GitHub or Google OAuth.

enforce_domain

Redirect to correct domain if host header does not match domain. Prevents DNS rebinding attacks. Default is false.

root_url

This is the full URL used to access Grafana from a web browser. This is important if you use Google or GitHub OAuth authentication (for the callback URL to be correct).

Note This setting is also important if you have a reverse proxy in front of Grafana that exposes it through a subpath. In that case add the subpath to the end of this URL setting.

static_root_path

The path to the directory where the front end files (HTML, JS, and CSS files). Default to public which is why the Grafana binary needs to be executed with working directory set to the installation path.

cert_file

Path to the certificate file (if protocol is set to https).

cert_key

Path to the certificate key file (if protocol is set to https).

[database]

Grafana needs a database to store users and dashboards (and other things). By default it is configured to use sqlite3 which is an embedded database (included in the main Grafana binary).

type

Either mysql, postgres or sqlite3, it's your choice.

path

Only applicable for sqlite3 database. The file path where the database will be stored.

host

Only applicable to MySQL or Postgres. Includes IP or hostname and port. For example, for MySQL running on the same host as Grafana: host = 127.0.0.1:3306

name

The name of the Grafana database. Leave it set to grafana or some other name.

user

The database user (not applicable for sqlite3).

password

The database user's password (not applicable for sqlite3).

ssl_mode

For postgres only, either disable, require or verify-full.

[security]

admin_user

The name of the default Grafana admin user (who has full permissions). Defaults to admin.

admin_password

The password of the default Grafana admin. Defaults to admin.

login_remember_days

The number of days the keep me logged in / remember me cookie lasts.

secret_key

Used for signing keep me logged in / remember me cookies.

disable_gravatar

Set to true to disable the use of Gravatar for user profile images. Default is false.

[users]

allow_sign_up

Set to false to prohibit users from being able to sign up / create user accounts. Defaults to true. The admin user can still create users from the Grafana Admin Pages

allow_org_create

Set to false to prohibit users from creating new organizations. Defaults to true.

auto_assign_org

Set to true to automatically add new users to the main organization (id 1). When set to false, new users will automatically cause a new organization to be created for that new user.

auto_assign_org_role

The role new users will be assigned for the main organization (if the above setting is set to true). Defaults to Viewer, other valid options are Admin and Editor.

[auth.anonymous]

enabled

Set to true to enable anonymous access. Defaults to false

org_name

Set the organization name that should be used for anonymous users. If you change your organization name in the Grafana UI this setting needs to be updated to match the new name.

org_role

Specify role for anonymous users. Defaults to Viewer, other valid options are Editor and Admin.

[auth.github]

You need to create a GitHub application (you find this under the GitHub profile page). When you create the application you will need to specify a callback URL. Specify this as callback:

http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/github

This callback URL must match the full HTTP address that you use in your browser to access Grafana, but with the prefix path of /login/github. When the GitHub application is created you will get a Client ID and a Client Secret. Specify these in the Grafana configuration file. For example:

[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
allow_sign_up = false
team_ids =

Restart the Grafana back-end. You should now see a GitHub login button on the login page. You can now login or sign up with your GitHub accounts.

You may allow users to sign-up via GitHub authentication by setting the allow_sign_up option to true. When this option is set to true, any user successfully authenticating via GitHub authentication will be automatically signed up.

team_ids

Require an active team membership for at least one of the given teams on GitHub. If the authenticated user isn't a member of at least one of the teams they will not be able to register or authenticate with your Grafana instance. For example:

[auth.github]
enabled = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email,read:org
team_ids = 150,300
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
allow_sign_up = false

[auth.google]

You need to create a Google project. You can do this in the Google Developer Console. When you create the project you will need to specify a callback URL. Specify this as callback:

http://<my_grafana_server_name_or_ip>:<grafana_server_port>/login/google

This callback URL must match the full HTTP address that you use in your browser to access Grafana, but with the prefix path of /login/google. When the Google project is created you will get a Client ID and a Client Secret. Specify these in the Grafana configuration file. For example:

[auth.google]
enabled = true
client_id = YOUR_GOOGLE_APP_CLIENT_ID
client_secret = YOUR_GOOGLE_APP_CLIENT_SECRET
scopes = https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
auth_url = https://accounts.google.com/o/oauth2/auth
token_url = https://accounts.google.com/o/oauth2/token
allowed_domains = mycompany.com mycompany.org
allow_sign_up = false

Restart the Grafana back-end. You should now see a Google login button on the login page. You can now login or sign up with your Google accounts. The allowed_domains option is optional, and domains were separated by space.

You may allow users to sign-up via Google authentication by setting the allow_sign_up option to true. When this option is set to true, any user successfully authenticating via Google authentication will be automatically signed up.

[auth.basic]

enabled

When enabled is true (default) the http api will accept basic authentication.

[auth.ldap]

enabled

Set to true to enable LDAP integration (default: false)

config_file

Path to the LDAP specific configuration file (default: /etc/grafana/ldap.toml)

For details on LDAP Configuration, go to the LDAP Integration page.

[auth.proxy]

This feature allows you to handle authentication in a http reverse proxy.

enabled

Defaults to false

header_name

Defaults to X-WEBAUTH-USER

header_property

Defaults to username but can also be set to email

auto_sign_up

Set to true to enable auto sign up of users who do not exist in Grafana DB. Defaults to true.

[session]

provider

Valid values are memory, file, mysql, postgres. Default is file.

provider_config

This option should be configured differently depending on what type of session provider you have configured.

  • file: session file path, e.g. data/sessions
  • mysql: go-sql-driver/mysql dsn config string, e.g. user:password@tcp(127.0.0.1:3306)/database_name
  • postgres: ex: user=a password=b host=localhost port=5432 dbname=c sslmode=disable

If you use MySQL or Postgres as the session store you need to create the session table manually.

Mysql Example:

CREATE TABLE `session` (
    `key`       CHAR(16) NOT NULL,
    `data`      BLOB,
    `expiry`    INT(11) UNSIGNED NOT NULL,
    PRIMARY KEY (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

The name of the Grafana session cookie.

Set to true if you host Grafana behind HTTPS only. Defaults to false.

session_life_time

How long sessions lasts in seconds. Defaults to 86400 (24 hours).

[analytics]

reporting_enabled

When enabled Grafana will send anonymous usage statistics to stats.grafana.org. No IP addresses are being tracked, only simple counters to track running instances, versions, dashboard & error counts. It is very helpful to us, so please leave this enabled. Counters are sent every 24 hours. Default value is true.

google_analytics_ua_id

If you want to track Grafana usage via Google analytics specify your Universal Analytics ID here. By default this feature is disabled.

[dashboards.json]

If you have a system that automatically builds dashboards as json files you can enable this feature to have the Grafana backend index those json dashboards which will make them appear in regular dashboard search.

enabled

true or false. Is disabled by default.

path

The full path to a directory containing your json dashboards.
