the cardinality of the request counter's "url" label, which might be required in some contexts.
|
||||||

For instance, if for a "/customer/:name" route you don't want to generate a time series for every
|
||||||
|
possible customer name, you could use this function:
|

|
|
||||||
|

|
url = strings.Replace(url, p.Value, ":name", 1)
|
||||||
|
break
|

|
}
|
||||||
|
}
|
||||||
|
return url
|
||||||
|
}
|
||||||
|
|
||||||
|
which would map "/customer/alice" and "/customer/bob" to their template "/customer/:name".
