Important: This documentation is about an older version. It's relevant only to the release noted, many of the features and functions have been updated or replaced. Please view the current version.

Installation

Configuration

Enterprise Open source

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.

Comments In .ini Files

Semicolons (the ; char) are the standard way to comment out lines in a .ini file.

A common problem is forgetting to uncomment a line in the custom.ini (or grafana.ini) file which causes the configuration option to be ignored.

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:

# default section
instance_name = ${HOSTNAME}

[security]
admin_user = admin

[auth.google]
client_secret = 0ldS3cretKey

Then you can override them using:

export GF_DEFAULT_INSTANCE_NAME=my-instance
export GF_SECURITY_ADMIN_USER=true
export GF_AUTH_GOOGLE_CLIENT_SECRET=newS3cretKey

instance_name

Set the name of the grafana-server instance. Used in logging and internal metrics and in clustering info. Defaults to: ${HOSTNAME}, which will be replaced with environment variable HOSTNAME, if that is empty or does not exist Grafana will try to use system calls to get the machine name.

[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.

plugins

Directory where grafana will automatically scan and look for plugins

provisioning

This feature is available in 5.0+

Folder that contains provisioning config files that grafana will apply on startup. Dashboards will be reloaded when the json files changes

[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' /usr/sbin/grafana-server

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

Note Grafana versions earlier than 3.0 are vulnerable to POODLE. So we strongly recommend to upgrade to 3.x or use a reverse proxy for ssl termination.

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).

router_logging

Set to true for Grafana to log all HTTP requests (not just errors). These are logged as Info level events to grafana log.

[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).

url

Use either URL or or the other fields below to configure the database Example: mysql://user:secret@host:port/database

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). If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;"""

ssl_mode

For Postgres, use either disable, require or verify-full. For MySQL, use either true, false, or skip-verify.

ca_cert_path

The path to the CA certificate to use. On many linux systems, certs can be found in /etc/ssl/certs.

client_key_path

The path to the client key. Only if server requires client authentication.

client_cert_path

The path to the client cert. Only if server requires client authentication.

server_cert_name

The common name field of the certificate used by the mysql or postgres server. Not necessary if ssl_mode is set to skip-verify.

max_idle_conn

The maximum number of connections in the idle connection pool.

max_open_conn

The maximum number of open connections to the database.

conn_max_lifetime

Sets the maximum amount of time a connection may be reused. The default is 14400 (which means 14400 seconds or 4 hours). For MySQL, this setting should be shorter than the wait_timeout variable.

log_queries

Set to true to log the sql calls and execution times.

[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. Set once on first-run. Defaults to admin.

allow_sign_up

Set to false to prohibit users from being able to sign up / create user accounts. Defaults to false. 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 false.

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. e.g. :

auto_assign_org_role = Viewer

viewers_can_edit

Viewers can edit/inspect dashboard settings in the browser. But not save the dashboard. Defaults to false.

[auth]

disable_login_form

Set to true to disable (hide) the login form, useful if you use OAuth, defaults to false.

disable_signout_menu

Set to true to disable the signout link in the side menu. useful if you use auth.proxy, defaults to false.

[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 OAuth application (you find this under the GitHub settings 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 OAuth 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
allow_sign_up = true
client_id = YOUR_GITHUB_APP_CLIENT_ID
client_secret = YOUR_GITHUB_APP_CLIENT_SECRET
scopes = user:email,read:org
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
api_url = https://api.github.com/user
team_ids =
allowed_organizations =

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
api_url = https://api.github.com/user
allow_sign_up = true

allowed_organizations

Require an active organization membership for at least one of the given organizations on GitHub. If the authenticated user isn’t a member of at least one of the organizations 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
auth_url = https://github.com/login/oauth/authorize
token_url = https://github.com/login/oauth/access_token
api_url = https://api.github.com/user
allow_sign_up = true
# space-delimited organization names
allowed_organizations = github google

[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 = true

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.generic_oauth]

This option could be used if have your own oauth service.

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/generic_oauth.

[auth.generic_oauth]

client_secret = YOUR_APP_CLIENT_SECRET
scopes =
auth_url =
token_url =
api_url =
allowed_domains = mycompany.com mycompany.org
allow_sign_up = true

Set api_url to the resource that returns OpenID UserInfo compatible information.

Set up oauth2 with Okta

First set up Grafana as an OpenId client “webapplication” in Okta. Then set the Base URIs to https://<grafana domain>/ and set the Login redirect URIs to https://<grafana domain>/login/generic_oauth.

Finally set up the generic oauth module like this:

[auth.generic_oauth]
name = Okta

then:
Add an App to the Grafana Connector:
- Display Name: Grafana
then:

Under the SSO tab on the Grafana App details page you’ll find the Client ID and Client Secret.

Your OneLogin Domain will match the url you use to access OneLogin.

Configure Grafana as follows:

[auth.generic_oauth]
name = OneLogin
enabled = true
allow_sign_up = true
client_id = <client id>
client_secret = <client secret>
scopes = openid email name
