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.
Configure Grafana
You can use Grafana Cloud to avoid installing, maintaining, and scaling your own instance of Grafana. Create a free account to get started, which includes free forever access to 10k metrics, 50GB logs, 50GB traces, 500VUh k6 testing & more.
Grafana has default and custom configuration files. You can customize your Grafana instance by modifying the custom configuration file or by using environment variables. To see the list of settings for a Grafana instance, refer to View server settings.
Note
After you add custom options, uncomment the relevant sections of the configuration file. Restart Grafana for your changes to take effect.
Configuration file location
The default settings for a Grafana instance are stored in the $WORKING_DIR/conf/defaults.ini
file. Do not change this file.
Depending on your OS, your custom configuration file is either the $WORKING_DIR/conf/custom.ini
file or the /usr/local/etc/grafana/grafana.ini
file. 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 for information about environmental variables, persistent storage, and building custom Docker images.
Windows
On Windows, the sample.ini
file is located in the same directory as defaults.ini
file. It 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 the settings defined in conf/defaults.ini
.
Remove comments in the .ini files
Grafana uses semicolons (the ;
char) to comment out lines in a .ini
file. You must uncomment each line in the custom.ini
or the grafana.ini
file that you are modify by removing ;
from the beginning of that line. Otherwise your changes will be ignored.
For example:
# The HTTP port to use
;http_port = 3000
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 = true
[feature_toggles]
enable = newNavigation
You can override variables 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=true
export GF_FEATURE_TOGGLES_ENABLE=newNavigation
Variable 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}/grafana
File 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/path
macOS: 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
min_tls_version
The TLS Handshake requires a minimum TLS version. The available options are TLS1.2 and TLS1.3. If you do not specify a version, the system uses TLS1.2.
http_addr
The host for the server to listen on. If your machine has more than one network interface, you can use this setting to expose the Grafana service on only one network interface and not have it available on others, such as the loopback interface. An empty value is equivalent to setting the value to 0.0.0.0
, which means the Grafana service binds to all interfaces.
In environments where network address translation (NAT) is used, ensure you use the network interface address and not a final public address; otherwise, you might see errors such as bind: cannot assign requested address
in the logs.
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 to put a web server like Nginx or Apache in front of Grafana and have them proxy requests to Grafana.
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 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
. If accessed without subpath Grafana will redirect to
an URL with the subpath.
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
).
certs_watch_interval
Controls whether cert_key
and cert_file
are periodically watched for changes.
Disabled, by default. When enabled, cert_key
and cert_file
are watched for changes. If there is change, the new certificates are loaded automatically.
Warning
After the new certificates are loaded, connections with old certificates will not work. You must reload the connections to the old certs for them to work.
socket_gid
GID where the socket should be set when protocol=socket
.
Make sure that the target group is in the group of Grafana process and that Grafana process is the file owner before you change this setting.
It is recommended to set the gid as http server user gid.
Not set when the value is -1.
socket_mode
Mode where the socket should be set when protocol=socket
. Make sure that Grafana process is the file owner before you change this setting.
socket
Path where the socket should be created when protocol=socket
. Make sure Grafana has appropriate permissions for that path 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.
[server.custom_response_headers]
This setting enables you to specify additional headers that the server adds to HTTP(S) responses.
exampleHeader1 = exampleValue1
exampleHeader2 = exampleValue2

cookie attribute and prevents the browser from sending this cookie along with cross-site requests. The main goal is to mitigate the risk of cross-origin information leakage. This setting also provides some protection against cross-site request forgery attacks (CSRF), read more about SameSite here. Valid values are lax
, strict
, none
, and disabled
. Default is lax
. 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
Set to true
if you want to enable HTTP Strict-Transport-Security
(HSTS) response header. Only use this when HTTPS is enabled in your configuration, or when there is another upstream system that ensures your application does HTTPS (like a frontend load balancer). HSTS tells browsers that the site should only be accessed using HTTPS.

Set to true
to enable the HSTS includeSubDomains option. Only applied if strict_transport_security is enabled. The default value is false
.
x_content_type_options
Set to false
to disable the X-Content-Type-Options response header. The X-Content-Type-Options response HTTP header is a marker used by the server to indicate that the MIME types advertised in the Content-Type headers should not be changed and be followed. The default value is true
.
x_xss_protection
Set to false
to disable the X-XSS-Protection header, which tells browsers to stop pages from loading when they detect reflected cross-site scripting (XSS) attacks. The default value is true
.
content_security_policy
Set to true
to add the Content-Security-Policy header to your requests. CSP allows to control resources that the user agent can load and helps prevent XSS attacks.
content_security_policy_template
Set the policy template that will be used when adding the Content-Security-Policy
header to your requests. $NONCE
in the template includes a random nonce.
content_security_policy_report_only
Set to true
to add the Content-Security-Policy-Report-Only
header to your requests. CSP in Report Only mode enables you to experiment with policies by monitoring their effects without enforcing them.
You can enable both policies simultaneously.

Set the policy template that will be used when adding the Content-Security-Policy-Report-Only
header to your requests. $NONCE
in the template includes a random nonce.
angular_support_enabled
This is set to false by default, meaning that the angular framework and support components will not be loaded. This means that all plugins and core features that depend on angular support will stop working.
The core features that depend on angular are:
- Old graph panel
- Old table panel
These features each have supported alternatives, and we recommend using them.
csrf_trusted_origins
List of additional allowed URLs to pass by the CSRF check. Suggested when authentication comes from an IdP.
csrf_additional_headers
List of allowed headers to be set by the user. Suggested to use for if authentication lives behind reverse proxies.

Enable this to automatically remove expired snapshots. Default is true
.
[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.json
as the default home dashboard location.
[sql_datasources]
max_open_conns_default
For SQL data sources (MySql, Postgres, MSSQL) you can override the default maximum number of open connections (default: 100). The value configured in data source settings will be preferred over the default value.
max_idle_conns_default
For SQL data sources (MySql, Postgres, MSSQL) you can override the default allowed number of idle connections (default: 100). The value configured in data source settings will be preferred over the default value.

oauth_skip_org_role_update_sync
Note
This option is removed from G11 in favor of OAuth provider specificskip_org_role_sync
settings. The following sections explain settings for each provider.
If you want to change the oauth_skip_org_role_update_sync
setting from true
to false
, then each provider you have set up, use the skip_org_role_sync
setting to specify whether you want to skip the synchronization.
Warning
Currently if no organization role mapping is found for a user, Grafana doesn’t update the user’s organization role. With Grafana 10, ifoauth_skip_org_role_update_sync
option is set tofalse
, users with no mapping will be reset to the default organization role on every login. Seeauto_assign_org_role
option.
skip_org_role_sync
skip_org_role_sync
prevents the synchronization of organization roles for a specific OAuth integration, while the deprecated setting oauth_skip_org_role_update_sync
affects all configured OAuth providers.
The default value for skip_org_role_sync
is false
.
With skip_org_role_sync
set to false
, the users’ organization and role is reset on every new login, based on the external provider’s role. See your provider in the tables below.
With skip_org_role_sync
set to true
, when a user logs in for the first time, Grafana sets the organization role based on the value specified in auto_assign_org_role
and forces the organization to auto_assign_org_id
when specified, otherwise it falls back to OrgID 1
.
Note: Enabling
skip_org_role_sync
also disables the synchronization of Grafana Admins from the external provider, as suchallow_assign_grafana_admin
is ignored.
Use this setting when you want to manage the organization roles of your users from within Grafana and be able to manually assign them to multiple organizations, or to prevent synchronization conflicts when they can be synchronized from another provider.

ha_label
The label is an optional string to include on each packet and stream. It uniquely identifies the cluster and prevents cross-communication issues when sending gossip messages in an environment with multiple clusters.
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

Sets a maximum number of times we’ll attempt to evaluate an alert rule before giving up on that evaluation. The default value is 1
.
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.
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.

[external_image_storage.s3]
endpoint
Optional endpoint URL (hostname or fully qualified URI) to override the default generated S3 endpoint. If you want to
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.
bucket
Bucket name for S3. e.g. grafana.snapshot.

secret_key
Secret key, e.g. AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA.
[external_image_storage.webdav]
url
URL where Grafana sends PUT request with images.
username
Basic auth username.
password

[external_image_storage.gcs]
key_file
Optional path to JSON key file associated with a Google service account to authenticate and authorize. If no value is provided it tries to use the application default credentials. Service Account keys can be created and downloaded from https://console.developers.google.com/permissions/serviceaccounts.
Service Account should have “Storage Object Writer” role. The access control model of the bucket needs to be “Set object-level and bucket-level permissions”. Grafana itself will make the images public readable when signed urls are not enabled.
bucket
Bucket Name on Google Cloud Storage.
path
Optional extra path inside bucket.
enable_signed_urls
If set to true, Grafana creates a signed URL for the image uploaded to Google Cloud Storage.

Sets the signed URL expiration, which defaults to seven days.
[external_image_storage.azure_blob]
account_name
Storage account name.
account_key
Storage account key

An auth token will be sent to and verified by the renderer. The renderer will deny any request without an auth token matching the one configured on the renderer.
server_url
URL to a remote HTTP image renderer service, e.g. http://localhost:8081/render, will enable Grafana to render panels and dashboards to PNG-images using HTTP requests to an external service.
callback_url
If the remote HTTP image renderer service runs on a different server than the Grafana server you may have to configure this to a URL where Grafana is reachable, e.g. http://grafana.domain/.
concurrent_render_request_limit
Concurrent render request limit affects when the /render HTTP endpoint is used. Rendering many images at the same time can overload the server,
which this setting can help protect against by only allowing a certain number of concurrent requests. Default is 30
.
default_image_width
Configures the width of the rendered image. The default width is 1000
.
default_image_height

. If disabled, it will use the hardcoded public key.
public_key_retrieval_on_startup
Force download of the public key for verifying plugin signature on startup. The default is false
. If disabled, the public key will be retrieved every 10 days. Requires public_key_retrieval_disabled
to be false to have any effect.
disable_plugins
Enter a comma-separated list of plugin identifiers to avoid loading (including core plugins). These plugins will be hidden in the catalog.
[live]
max_connections
Note
Available in Grafana v8.0 and later versions.
The max_connections
option specifies the maximum number of connections to the Grafana Live WebSocket endpoint per Grafana server instance. Default is 100
.
Refer to Grafana Live configuration documentation if you specify a number higher than default since this can require some operating system and infrastructure tuning.
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 the 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.
