This page describes Grafana Enterprise-specific configuration options that you can specify in a `.ini` configuration file or using environment variables. Refer to [Configuration]({{< relref "../administration/configuration.md" >}}) for more information about available configuration options.
> **Note:** Available in Grafana Enterprise v8.3+.
When set to `aws`, Grafana will validate its license status with Amazon Web Services (AWS) instead of with Grafana Labs. Only use this setting if you purchased an Enterprise license from AWS Marketplace. Defaults to empty, which means that by default Grafana Enterprise will validate using a license issued by Grafana Labs. For details about licenses issued by AWS, refer to [Activate a Grafana Enterprise license purchased through AWS Marketplace]({{< relref "../enterprise/license/activate-aws-marketplace-license/" >}}).
By [exporting usage logs]({{< relref "usage-insights/export-logs.md" >}}), you can directly query them and create dashboards of the information that matters to you most, such as dashboard errors, most active organizations, or your top-10 most-used queries.
Interval for writing dashboard usage stats buffer to database.
### buffer_write_timeout
Timeout for writing dashboard usage stats buffer to database.
### rollup_interval
Interval for trying to roll up per dashboard usage summary. Only rolled up at most once per day.
### rollup_timeout
Timeout for trying to rollup per dashboard usage summary.
## [analytics.views]
### recent_users_age
Age for recent active users.
## [reporting]
### rendering_timeout
Timeout for each panel rendering request.
### concurrent_render_limit
Maximum number of concurrent calls to the rendering service.
### image_scale_factor
Scale factor for rendering images. Value `2` is enough for monitor resolutions, `4` would be better for printed material. Setting a higher value affects performance and memory.
[Auditing]({{< relref "auditing.md" >}}) allows you to track important changes to your Grafana instance. By default, audit logs are logged to file but the auditing feature also supports sending logs directly to Loki.
### enabled
Enable the auditing feature. Defaults to false.
### loggers
List of enabled loggers.
### log_dashboard_content
Keep dashboard content in the logs (request or response fields). This can significantly increase the size of your logs.
## [auditing.logs.file]
### path
Path to logs folder.
### max_files
Maximum log files to keep.
### max_file_size_mb
Max size in megabytes per log file.
## [auditing.logs.loki]
### url
Set the URL for writing logs to Loki.
### tls
If true, it establishes a secure connection to Loki. Defaults to true.
List of comma- or space-separated Organization:OrgId:Role mappings. Organization can be `*` meaning "All users". Role is optional and can have the following values: `Viewer`, `Editor` or `Admin`.
Encryption algorithm used to encrypt secrets stored in the database and cookies. Possible values are `aes-cfb` (default) and `aes-gcm`. AES-CFB stands for _Advanced Encryption Standard_ in _cipher feedback_ mode, and AES-GCM stands for _Advanced Encryption Standard_ in _Galois/Counter Mode_.
> **Note:** This setting enables the caching feature, but it does not turn on query caching for any data source. To turn on query caching for a data source, update the setting on the data source configuration page. For more information, refer to the [query caching docs]({{< relref "./query-caching.md#enable-and-configure-query-caching" >}}).
_Time to live_ (TTL) is the time that a query result is stored in the caching system before it is deleted or refreshed. This setting defines the time to live for query caching, when TTL is not configured in data source settings. The default value is `1m` (1 minute).
### max_ttl
The max duration that a query result is stored in the caching system before it is deleted or refreshed. This value will override `ttl` config option or data source setting if the `ttl` value is greater than `max_ttl`. To disable this constraint, set this value to `0s`.
The default is `0s` (disabled).
> **Note:** Disabling this constraint is not recommended in production environments.
This value limits the size of a single cache value. If a cache value (or query result) exceeds this size, then it is not cached. To disable this limit, set this value to `0`.
When 'enabled' is `true`, query values in the cache are encrypted.
The default is `false`.
### encryption_key
A string used to generate a key for encrypting the cache. For the encrypted cache data to persist between Grafana restarts, you must specify this key. If it is empty when encryption is enabled, then the key is automatically generated on startup, and the cache clears upon restarts.
When storing cache data in-memory, this setting defines how often a background process cleans up stale data from the in-memory cache. More frequent "garbage collection" can keep memory usage from climbing but will increase CPU usage.
The maximum size of the in-memory cache in megabytes. Once this size is reached, new cache items are rejected. For more flexible control over cache eviction policies and size, use the Redis or Memcached backend.
A space-separated list of memcached servers. Example: `memcached-server-1:11211 memcached-server-2:11212 memcached-server-3:11211`. Or if there's only one server: `memcached-server:11211`.
