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"

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 or the PRI verb (for HTTP/2), then the value for the method label becomes EXTENSION_METHOD.
