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.
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.
To see all settings currently applied to the Grafana server, refer to View server settings.
Config file locations
The default settings for a Grafana instance are stored in the $WORKING_DIR/conf/defaults.ini file. Do not change the location in this file.
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
--configparameter
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 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. For a Grafana instance installed using Homebrew, edit the grafana.ini file directly. Otherwise, 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 = 3000A common problem is forgetting to uncomment a line in the custom.ini (or grafana.ini) file which causes the configuration option to be ignored.
Override configuration with environment variables
Do not use environment variables to add new configuration settings. Instead, use environmental variables to override existing options.
To override an option:
GF_<SectionName>_<KeyName>Where the section name is the text within the brackets. Everything should be uppercase, . and - 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
[plugin.grafana-image-renderer]
rendering_ignore_https_errors = trueYou 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
export GF_PLUGIN_GRAFANA_IMAGE_RENDERER_RENDERING_IGNORE_HTTPS_ERRORS=trueVariable expansion
Note: Only available in Grafana 7.1+.
If any of your options contains the expression $__<provider>{<argument>}
or ${<environment variable>}, then they will be processed by Grafana’s
variable expander. The expander runs the provider with the provided argument
to get the final value of the option.
There are three providers: env, file, and vault.
Env provider
The env provider can be used to expand an environment variable. If you
set an option to $__env{PORT} the PORT environment variable will be
used in its place. For environment variables you can also use the
short-hand syntax ${PORT}.
Grafana’s log directory would be set to the grafana directory in the
directory behind the LOGDIR environment variable in the following
example.
[paths]
logs = $__env{LOGDIR}/grafanaFile provider
file reads a file from the filesystem. It trims whitespace from the
beginning and the end of files.
The database password in the following example would be replaced by
the content of the /etc/secrets/gf_sql_password file:
[database]
password = $__file{/etc/secrets/gf_sql_password}Vault provider
The vault provider allows you to manage your secrets with Hashicorp Vault.
Vault provider is only available in Grafana Enterprise v7.1+. For more information, refer to Vault integration in Grafana Enterprise.
app_mode
Options are production and development. Default is production. Do not change this option unless you are working on Grafana development.
instance_name
Set the name of the grafana-server instance. Used in logging, internal metrics, and 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 stores 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.logs:
./grafana-server --config /custom/config.ini --homepath /custom/homepath cfg:default.paths.logs=/custom/pathmacOS: By default, the log file should be located at /usr/local/var/log/grafana/grafana.log.
plugins
Directory where Grafana automatically scans and looks for plugins. For information about manually or automatically installing plugins, refer to Install Grafana plugins.
macOS: By default, the Mac plugin location is: /usr/local/var/lib/grafana/plugins.
provisioning
Folder that contains provisioning config files that Grafana will apply on startup. Dashboards will be reloaded when the json files changes.
[server]
protocol
http,https,h2 or socket
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-serverOr redirect port 80 to the Grafana port using:
$ sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 3000Another way is to put a web server like Nginx or Apache in front of Grafana and have them proxy requests to Grafana.
domain
enforce_domain
Redirect to correct domain if the host header does not match the 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
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 is accessible on
http://localhost:3000/grafana.
router_logging
Set to true for Grafana to log all HTTP requests (not just errors). These are logged as Info level events to the Grafana log.
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).
socket
Path where the socket should be created when protocol=socket. Make sure that Grafana has appropriate permissions before you change this setting.
cdn_url
Note: Available in Grafana v7.4 and later versions.
Specify a full HTTP URL address to the root of your Grafana CDN assets. Grafana will add edition and version paths.
For example, given a cdn url like https://cdn.myserver.com grafana will try to load a javascript file from
http://cdn.myserver.com/grafana-oss/7.4.0/public/build/app.<hash>.js.
read_timeout
Sets the maximum time using a duration format (5s/5m/5ms) before timing out read of an incoming request and closing idle connections.
0 means there is no timeout for reading the request.
[database]

track running instances, versions, dashboard and error counts. It is very helpful
to us, so please leave this enabled. Counters are sent every 24 hours. Default
value is true.
check_for_updates
Set to false to disable all checks to https://grafana.com for new versions of installed plugins and to the Grafana GitHub repository to check for a newer version of Grafana. The version information is used in some UI views to notify that a new Grafana update or a plugin update exists. This option does not cause any auto updates, nor send any sensitive information. The check is run every 10 minutes.
google_analytics_ua_id

Using value disabled does not add any SameSite attribute to cookies.
allow_embedding
When false, the HTTP header X-Frame-Options: deny will be set in Grafana HTTP responses which will instruct
browsers to not allow rendering Grafana in a <frame>, <iframe>, <embed> or <object>. The main goal is to
mitigate the risk of Clickjacking. Default is false.
strict_transport_security

[dashboards]
versions_to_keep
Number dashboard versions to keep (per dashboard). Default: 20, Minimum: 1.
min_refresh_interval
Only available in Grafana v6.7+.
This feature prevents users from setting the dashboard refresh interval to a lower value than a given interval value. The default interval value is 5 seconds.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.
As of Grafana v7.3, this also limits the refresh interval options in Explore.
default_home_dashboard_path
Path to the default home dashboard. If this value is empty, then Grafana uses StaticRootPath + “dashboards/home.json”.
Note: On Linux, Grafana uses
/usr/share/grafana/public/dashboards/home.jsonas the default home dashboard location.

ha_peer_timeout
Time to wait for an instance to send a notification via the Alertmanager. In HA, each Grafana instance will
be assigned a position (e.g. 0, 1). We then multiply this position with the timeout to indicate how long should
each instance wait before sending the notification to take into account replication lag. The default value is 15s.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.
ha_gossip_interval
The interval between sending gossip messages. By lowering this value (more frequent) gossip messages are propagated
across cluster more quickly at the expense of increased bandwidth usage. The default value is 200ms.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.
ha_push_pull_interval
The interval between gossip full state syncs. Setting this interval lower (more frequent) will increase convergence speeds
across larger clusters at the expense of increased bandwidth usage. The default value is 60s.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.

The timeout string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.
max_attempts
Sets a maximum number of times we’ll attempt to evaluate an alert rule before giving up on that evaluation. The default value is 3. This option has a legacy version in the alerting section that takes precedence.
min_interval
Sets the minimum interval to enforce between rule evaluations. The default value is 10s which equals the scheduler interval. Rules will be adjusted if they are less than this value or if they are not multiple of the scheduler interval (10s). Higher values can help with resource management as we’ll schedule fewer evaluations over time. This option has a legacy version in the alerting section that takes precedence.
The interval string is a possibly signed sequence of decimal numbers, followed by a unit suffix (ms, s, m, h, d), e.g. 30s or 1m.
Note. This setting has precedence over each individual rule frequency. If a rule frequency is lower than this value, then this value is enforced.

keep the default, just leave this empty. You must still provide a region value if you specify an endpoint.
path_style_access
Set this to true to force path-style addressing in S3 requests, i.e., http://s3.amazonaws.com/BUCKET/KEY, instead
of the default, which is virtual hosted bucket addressing when possible (http://BUCKET.s3.amazonaws.com/KEY).
Note: This option is specific to the Amazon S3 service.
bucket_url
(for backward compatibility, only works when no bucket or region are configured) Bucket URL for S3. AWS region can be specified within URL or defaults to ‘us-east-1’, e.g.

0 disables Grafana Live, -1 means unlimited connections.
allowed_origins
Note: Available in Grafana v8.0.4 and later versions.
The allowed_origins option is a comma-separated list of additional origins (Origin header of HTTP Upgrade request during WebSocket connection establishment) that will be accepted by Grafana Live.
If not set (default), then the origin is matched over root_url which should be sufficient for most scenarios.
Origin patterns support wildcard symbol “*”.
For example:
[live]
allowed_origins = "https://*.example.com"ha_engine
Note: Available in Grafana v8.1 and later versions.
Experimental
The high availability (HA) engine name for Grafana Live. By default, it’s not set. The only possible value is “redis”.
For more information, refer to Configure Grafana Live HA setup.

Instruct headless browser instance to use a default language when not provided by Grafana, e.g. when rendering panel image of alert. Refer to the HTTP header Accept-Language to understand how to format this value, e.g. ‘fr-CH, fr;q=0.9, en;q=0.8, de;q=0.7, *;q=0.5’.
rendering_viewport_device_scale_factor
Instruct headless browser instance to use a default device scale factor when not provided by Grafana, e.g. when rendering panel image of alert.
Default is 1. Using a higher value will produce more detailed images (higher DPI), but requires more disk space to store an image.
rendering_ignore_https_errors
Instruct headless browser instance whether to ignore HTTPS errors during navigation. Per default HTTPS errors are not ignored. Due to the security risk, we do not recommend that you ignore HTTPS errors.
rendering_verbose_logging
Instruct headless browser instance whether to capture and log verbose information when rendering an image. Default is false and will only capture and log error messages.
When enabled, debug messages are captured and logged as well.
For the verbose information to be included in the Grafana server log you have to adjust the rendering log level to debug, configure [log].filter = rendering:debug.
rendering_dumpio
Instruct headless browser instance whether to output its debug and error messages into running process of remote rendering service. Default is false.
It can be useful to set this to true when troubleshooting.

Mode clustered will make sure that only a maximum of browsers/incognito pages can execute concurrently.
Mode reusable will have one browser instance and will create a new incognito page on each request.
rendering_clustering_mode
When rendering_mode = clustered, you can instruct how many browsers or incognito pages can execute concurrently. Default is browser and will cluster using browser instances.
Mode context will cluster using incognito pages.
rendering_clustering_max_concurrency
When rendering_mode = clustered, you can define the maximum number of browser instances/incognito pages that can execute concurrently. Default is 5.
rendering_clustering_timeout
Note: Available in grafana-image-renderer v3.3.0 and later versions.
When rendering_mode = clustered, you can specify the duration a rendering request can take before it will time out. Default is 30 seconds.
