- [Datadog](./datadog.md)
|
|
- [InfluxDB](./influxdb.md)
|
|
- [InfluxDB2](./influxdb2.md)
|
|
- [Prometheus](./prometheus.md)
|
|
- [StatsD](./statsd.md)

## Labels
|
|
|
|
Here is a comprehensive list of labels that are provided by the metrics:
|
|
|
|
| Label | Description | example |
|
|
|---------------|---------------------------------------|----------------------------|
|
|
| `cn` | Certificate Common Name | "example.com" |
|
|
| `code` | Request code | "200" |
|
|
| `entrypoint` | Entrypoint that handled the request | "example_entrypoint" |
|
|
| `method` | Request Method | "GET" |
|
|
| `protocol` | Request protocol | "http" |
|
|
| `router` | Router that handled the request | "example_router" |
|
|
| `sans` | Certificate Subject Alternative NameS | "example.com" |
|
|
| `serial` | Certificate Serial Number | "123..." |
|
|
| `service` | Service that handled the request | "example_service@provider" |
|
|
| `tls_cipher` | TLS cipher used for the request | "TLS_FALLBACK_SCSV" |
|
|
| `tls_version` | TLS version used for the request | "1.0" |
|
|
| `url` | Service server url | "http://example.com" |
|
|
|
|
!!! info "`method` label value"
|
|
|
|
If the HTTP method verb on a request is not one defined in the set of common methods for [`HTTP/1.1`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods)
|
|
or the [`PRI`](https://datatracker.ietf.org/doc/html/rfc7540#section-11.6) verb (for `HTTP/2`),
|
|
then the value for the method label becomes `EXTENSION_METHOD`.
