The hyperglass API is based on the powerful [FastAPI](https://fastapi.tiangolo.com/) framework, which includes automatic API documentation using the [OpenAPI](https://www.openapis.org/) specification. If you plan to provide your users with API access to your hyperglass instance, it is highly recommended to leave this enabled.
FastAPI provides built in support for both [Swagger UI](https://swagger.io/tools/swagger-ui/) and [Redoc](https://redocly.github.io/redoc/), which are open source projects that create a pretty web UI from an OpenAPI specification.

<Admonition type="tip" title="From the developer">
I'm partial to Redoc, partially because I find it to be more aesthetically pleasing, and
partially because it's written in <a href="https://reactjs.org/">ReactJS</a>, just like the
hyperglass UI. At some point, I plan to migrate away from the built-in Redoc page and integrate
Redoc directly with hyperglass.

import Link from "@docusaurus/Link";

hyperglass uses [Redis](https://redis.io/) for cache storage. Every query is cached and automatically expired from the cache after a configurable timeout period.
Common Redis parameters are configurable, in case you already have a dedicated Redis server you'd prefer to use, instead of running it on the same server as hyperglass:
| Parameter | Type | Default | Description |
| :---------- | :-----: | :------------ | :--------------------------------------------------------------------------- |
| `host` | String | `'localhost'` | Redis server IP address or hostname. |
| `port` | Integer | `6379` | Redis server TCP port. |
| `database` | Integer | `0` | Database ID for hyperglass. |
| `timeout` | Integer | `120` | Time in seconds query output will be kept in the Redis cache. |
| `show_text` | Boolean | `true` | Show the <Link to="/docs/ui#text">cache message</Link> in the hyperglass UI. |
<Admonition type="important" title="Caching">
hyperglass caches every query response to a Redis database, and always responds to a request
with the cached value. If hyperglass receives a query for which it has no matching cached entry,
the query parameters are used to created a new cache entry, hyperglass executes the request
normally, writes the response to the cache, and then returns the response to the end user.

## Example
```yaml
cache:
database: 0
host: localhost
port: 6379
show_text: true
timeout: 120

hyperglass is meant to be _extremely_ customizable, but with reasonable defaults that most operators won't need to override. Even though there are a _lot_ of configuration options, all of them can be left untouched and hyperglass will work (although, it's recommended to at least set the organization name).

# Global Settings
The following global settings can be set in `hyperglass.yaml`:
| Parameter | Type | Default | Description |
| :----------------- | :-----: | :----------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `debug` | Boolean | `false` | Enable application-wide debug mode. **This will generate a log of logs!** |
| `developer_mode` | Boolean | `false` | If enabled, the hyperglass backend (Python) and frontend (React/Javascript) applications are "unlinked", so that React tools can be used for front end development. A `<Debugger />` convenience component is also displayed in the UI for easier UI development.' |
| `primary_asn` | String | `'65000'` | Your network's primary ASN. This field is used to set some useful defaults such as the subtitle and PeeringDB URL. |
| `org_name` | String | `'Beloved Hyperglass User'` | Your organization's name. This field is used in the UI & API documentation to set fields such as `<meta/>` HTML tags for SEO and the terms & conditions footer component. |
| `site_title` | String | `'hyperglass'` | The name of your hyperglass site. This field is used in the UI & API documentation to set fields such as the `<title/>` HTML tag, and the terms & conditions footer component. |
| `site_description` | String | `'{org_name} Network Looking Glass'` | A short description of your hyperglass site. This field is used in th UI & API documentation to set the `<meta name="description"/>` tag. `{org_name}` may be used to insert the value of the `org_name` field. |
| `site_keywords` | List | | Keywords pertaining to your hyperglass site. This field is used to generate `<meta name="keywords"/>` HTML tags, which helps tremendously with [SEO](https://support.google.com/webmasters/answer/7451184). |
| `request_timeout` | Integer | `30` | Global timeout in seconds for all requests. The UI uses this field's exact value when submitting queries. The backend uses this field's value, minus one second, for its own timeout handling. This is to ensure a contextual timeout error is presented to the end user in the event of a backend application timeout. |
| `listen_address` | String | `'localhost'` | Local IP Address or hostname the hyperglass application listens on to serve web traffic. |
| `listen_port` | Integer | `8001` | Local TCP port the hyperglass application listens on to serve web traffic. |
| `log_file` | String | | Path to a log file to which hyperglass can write logs. If none is set, hyperglass will write logs to a file located at `/tmp/`, with a uniquely generated name for each time hyperglass is started. |
| `cors_origins` | List | `[]` | Allowed [CORS](https://developer.mozilla.org/docs/Web/HTTP/CORS) hosts. By default, no CORS hosts are allowed. |
#### Example
```yaml
debug: false
developer_mode: false
org_name: Beloved Hyperglass User
site_title: hyperglass
site_description: "{org_name} Network Looking Glass"
site_keywords: [hyperglass, looking glass, routing, bgp]
request_timeout: 30
listen_address: localhost
listen_port: 8001
log_file: /tmp/hyperglass.log
cors_origins: [localhost:3000, 192.0.2.1]

| Parameter | Type | Default | Description |
| :--------------------- | :----: | :-------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `acl_denied` | String | `'"{target} is a member of {denied_network}, which is not allowed."'` | Displayed when a query target is explicitly denied by a matched VRF's ACL entry. `{target}` and `{denied_network}` will be replaced with the denied query target and the ACL entry that caused it to be denied. |
| `acl_not_allowed` | String | `'{target} is not allowed.'` | Displayed when a query target is implicitly denied by a matched VRF's ACL. `{target}` will be replaced with the denied query target. |
| `authentication_error` | String | `'Authentication error occurred.'` | Displayed when hyperglass is unable to authenticate to a configured device. Usually, this indicates a configuration error. `{device_name}` and `{error}` will be replaced with the device in question and the specific connection error. |
| `connection_error` | String | `'Error connecting to {device_name}: {error}'` | Displayed when hyperglass is unable to connect to a configured device. Usually, this indicates a configuration error. `{device_name}` and `{error}` will be replaced with the device in question and the specific connection error. |
| `feature_not_enabled` | String | `'{feature} is not enabled for {device_name}.'` | Displayed when a query type is submitted that is not supported or disabled. The UI performs validation of supported query types prior to submitting any requests, so this is primarily relevant to the hyperglass API. `{feature}` and `{device_name}` will be replaced with the disabled feature and the selected device/location. |
| `general` | String | `'Something went wrong.'` | Displayed when generalized errors occur. Seeing this error message may indicate a bug in hyperglass, as most other errors produced are highly contextual. If you see this in the wild, try enabling <Link to="/docs/configuration#global-settings"><Code>debug</Code></Link> mode and review the logs to pinpoint the source of the error. |
| `invalid_field` | String | `'{input} is an invalid {field}.'` | Displayed when a query field contains an invalid or unsupported value. `{input}` and `{field}` will be replaced with the invalid input value and corresponding field name. |
| `invalid_input` | String | `'{target} is not a valid {query_type} target.'` | Displayed when a query target's value is invalid in relation to the corresponding query type. `{target}` and `{query_type}` will be replaced with the invalid target and corresponding query type. |
| `no_input` | String | `'{field} must be specified.'` | Displayed when no a required field is not specified. `{field}` will be replaced with the `display_name` of the field that was omitted. |
| `no_output` | String | `'No output.'` | Displayed when hyperglass can connect to a device and execute a query, but the response is empty. |
| `no_response` | String | `'No response.'` | Displayed when hyperglass can connect to a device, but no output is able to be read. Seeing this error may indicate a bug in hyperglass or one of its dependencies. If you see this in the wild, try enabling <Link to="/docs/configuration#global-settings"><Code>debug</Code></Link> mode and review the logs to pinpoint the source of the error. |
| `request_timeout` | String | `'Request timed out.'` | Displayed when the <Link to="/docs/configuration#global-settings"><Code>request_timeout</Code></Link> time expires. |
| `vrf_not_associated` | String | `'VRF {vrf_name} is not associated with {device_name}.'` | Displayed when a query request's VRF field value contains a VRF that is not configured or associated with the corresponding location/device. The UI automatically filters out VRFs that are not configured on a selected device, so this error is most likely to appear when using the hyperglass API. `{vrf_name}` and `{device_name}` will be replaced with the VRF in question and corresponding device. |
| `vrf_not_found` | String | `'RF {vrf_name} is not defined.'` | Displayed when a query VRF is not configured on any devices. The UI only shows configured VRFs, so this error is most likely to appear when using the hyperglass API. `{vrf_name}` will be replaced with the VRF in question. |
## Example
```yaml
messages:
acl_denied: "{target} is a member of {denied_network}, which is not allowed."
acl_not_allowed: "{target} is not allowed."
authentication_error: Authentication error occurred.
connection_error: "Error connecting to {device_name}: {error}"
feature_not_enabled: "{feature} is not enabled for {device_name}."
general: Something went wrong.
invalid_field: "{input} is an invalid {field}."
invalid_input: "{target} is not a valid {query_type} target."
no_input: "{field} must be specified."
no_output: No output.
no_response: No response.
request_timeout: Request timed out.
vrf_not_associated: VRF {vrf_name} is not associated with {device_name}.
vrf_not_found: VRF {vrf_name} is not defined.
