Enables anonymous census reporting. To opt out of census reporting, set this to False.
This data enables the project maintainers to estimate how many NetBox deployments exist and track the adoption of new versions over time. Census reporting effects a single HTTP request each time a worker starts. The only data reported by this function are the NetBox version, Python version, and a pseudorandom unique identifier.
The number of days to retain logged changes (object creations, updates, and deletions). Set this to `0` to retain
changes in the database indefinitely.
!!! warning
If enabling indefinite changelog retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.
The maximum size (in bytes) of an incoming HTTP request (i.e. `GET` or `POST` data). Requests which exceed this size will raise a `RequestDataTooBig` exception.
By default, NetBox will prevent the creation of duplicate prefixes and IP addresses in the global table (that is, those which are not assigned to any VRF). This validation can be disabled by setting `ENFORCE_GLOBAL_UNIQUE` to False.
The maximum amount (in bytes) of uploaded data that will be held in memory before being written to the filesystem. Changing this setting can be useful for example to be able to upload files bigger than 2.5MB to custom scripts for processing.
If enabling indefinite job results retention, it is recommended to periodically delete old entries. Otherwise, the database may eventually exceed capacity.

## MAINTENANCE_MODE
!!! tip "Dynamic Configuration Parameter"
Default: False
Setting this to True will display a "maintenance mode" banner at the top of every page. Additionally, NetBox will no longer update a user's "last active" time upon login. This is to allow new logins when the database is in a read-only state. Recording of login times will resume when maintenance mode is disabled.
This specifies the URL to use when presenting a map of a physical location by street address or GPS coordinates. The URL must accept either a free-form street address or a comma-separated pair of numeric coordinates appended to it. Set this to `None` to disable the "map it" button within the UI.
A web user or API consumer can request an arbitrary number of objects by appending the "limit" parameter to the URL (e.g. `?limit=1000`). This parameter defines the maximum acceptable limit. Setting this to `0` or `None` will allow a client to retrieve _all_ matching objects at once with no limit by specifying `?limit=0`.
Toggle the availability Prometheus-compatible metrics at `/metrics`. See the [Prometheus Metrics](../integrations/prometheus-metrics.md) documentation for more details.
This parameter defines the URL of the repository that will be checked for new NetBox releases. When a new release is detected, a message will be displayed to administrative users on the home page. This can be set to the official repository (`'https://api.github.com/repos/netbox-community/netbox/releases'`) or a custom fork. Set this to `None` to disable automatic update checks.
!!! note
The URL provided **must** be compatible with the [GitHub REST API](https://docs.github.com/en/rest).

## RQ_DEFAULT_TIMEOUT
Default: `300`
The maximum execution time of a background task (such as running a custom script), in seconds.
This parameter controls how frequently a failed job is retried, up to the maximum number of times specified by `RQ_RETRY_MAX`. This must be either an integer specifying the number of seconds to wait between successive attempts, or a list of such values. For example, `[60, 300, 3600]` will retry the task after 1 minute, 5 minutes, and 1 hour.
---
## RQ_RETRY_MAX
!!! note
This parameter was added in NetBox v3.5.
Default: `0` (retries disabled)
The maximum number of times a background task will be retried before being marked as failed.
