Configuration

Grafana has a number of configuration options that you can specify in a .ini configuration file or specified using environment variables.

Note: You must restart Grafana for any configuration changes to take effect.

Config file locations

Do not change defaults.ini! Grafana defaults are stored in this file. Depending on your OS, make all configuration changes in either custom.ini or grafana.ini.

• 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

Linux

If you installed Grafana using the deb or rpm packages, then your configuration file is located at /etc/grafana/grafana.ini and a separate custom.ini is not used. This path is specified in the Grafana init.d script using --config file parameter.

Docker

Refer to [Configure a Grafana Docker image]({{< relref "configure-docker.md" >}}) for information about environmental variables, persistent storage, and building custom Docker images.

Windows

sample.ini is in the same directory as defaults.ini and contains all the settings commented out. Copy sample.ini and name it custom.ini.

MacOS

By default, the configuration file is located at /usr/local/etc/grafana/grafana.ini. To configure Grafana, add a configuration file named custom.ini to the conf folder to override any of the settings defined in conf/defaults.ini.

Comments in .ini Files

Semicolons (the ; char) are the standard way to comment out lines in a .ini file. If you want to change a setting, you must delete the semicolon (;) in front of the setting before it will work.

Example

# The http port  to use
;http_port = 3000

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.

Configure with environment variables

All options in the configuration file 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 uppercase, . should be replaced by _. For example, if you have these configuration settings:

# default section
instance_name = ${HOSTNAME}

[security]
admin_user = admin

[auth.google]
client_secret = 0ldS3cretKey

You can override them on Linux machines with:

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

For any changes to conf/grafana.ini (or corresponding environment variables) to take effect, you must restart Grafana for the changes to take effect.

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.

macOS: The default SQLite database is located at /usr/local/var/lib/grafana

temp_data_lifetime

How long temporary images in data directory should be kept. Defaults to: 24h. Supported modifiers: h (hours), m (minutes), for example: 168h, 30m, 10h30m. Use 0 to never clean up temporary files.

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. You can override it in the configuration file or in the default environment variable file. However, please note that by overriding this the default log path will be used temporarily until Grafana has fully initialized/started.

Override log path using the command line argument cfg:default.paths.log:

./grafana-server --config /custom/config.ini --homepath /custom/homepath cfg:default.paths.logs=/custom/path

macOS: By default, the log file should be located at /usr/local/var/log/grafana/grafana.log.

plugins

Directory where Grafana will automatically scan and look for plugins. Manually or automatically install any plugins here.

macOS: By default, the Mac plugin location is: /usr/local/var/lib/grafana/plugins.

provisioning

Folder that contains [provisioning]({{< relref "../administration/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,https,h2 or socket

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.

socket

Path where the socket should be created when protocol=socket. Please make sure that Grafana has appropriate permissions.

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.

serve_from_sub_path

Available in 6.3 and above

Serve Grafana from subpath specified in root_url setting. By default it is set to false for compatibility reasons.

By enabling this setting and using a subpath in root_url above, e.g. root_url = http://localhost:3000/grafana, Grafana will be accessible on http://localhost:3000/grafana.

static_root_path

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

enable_gzip

Set this option to true to enable HTTP compression, this can improve transfer speed and bandwidth utilization. It is recommended that most users set it to true. By default it is set to false for compatibility reasons.

cert_file

Path to the certificate file (if protocol is set to https or h2).

cert_key

Path to the certificate key file (if protocol is set to https or h2).

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 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 or in case of Unix sockets the path to it. For example, for MySQL running on the same host as Grafana: host = 127.0.0.1:3306 or with Unix sockets: host = /var/run/mysqld/mysqld.sock

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. For example """#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.

cache_mode

For "sqlite3" only. Shared cache setting used for connecting to the database. (private, shared) Defaults to private.

---

[remote_cache]

type

Either redis, memcached or database. Defaults to database

connstr

The remote cache connection string. The format depends on the type of the remote cache.

Database

Leave empty when using database since it will use the primary database.

Redis

Example connstr: addr=127.0.0.1:6379,pool_size=100,db=0,ssl=false

• addr is the host : port of the redis server.
• pool_size (optional) is the number of underlying connections that can be made to redis.
• db (optional) is the number indentifer of the redis database you want to use.
• ssl (optional) is if SSL should be used to connect to redis server. The value may be true, false, or insecure. Setting the value to insecure skips verification of the certificate chain and hostname when making the connection.

Memcache

Example connstr: 127.0.0.1:11211

You can also use the standard JAEGER_* environment variables to configure Jaeger. See the table at the end of https://www.jaegertracing.io/docs/1.16/client-features/ for the full list. Environment variables will override any settings provided here.

address

The host:port destination for reporting spans. (ex: localhost:6381)

Can be set with the environment variables JAEGER_AGENT_HOST and JAEGER_AGENT_PORT.

always_included_tag

Comma-separated list of tags to include in all new spans, such as tag1:value1,tag2:value2.

Can be set with the environment variable JAEGER_TAGS (use = instead of : with the environment variable).

sampler_type

Default value is const.

Specifies the type of sampler: const, probabilistic, ratelimiting, or remote.

Refer to https://www.jaegertracing.io/docs/1.16/sampling/#client-sampling-configuration for details on the different tracing types.

Can be set with the environment variable JAEGER_SAMPLER_TYPE.

sampler_param

Default value is 1.

This is the sampler configuration parameter. Depending on the value of sampler_type, it can be 0, 1, or a decimal value in between.

• For const sampler, 0 or 1 for always false/true respectively
• For probabilistic sampler, a probability between 0 and 1.0
• For rateLimiting sampler, the number of spans per second
