Metrics
Client middleware to record metrics for the http4s client.
This middleware will record:
- Number of active requests
- Time duration to receive the response headers
- Time duration to process the whole response body
- Time duration of errors, timeouts and other abnormal terminations
This middleware can be extended to support any metrics ecosystem by implementing the org.http4s.metrics.MetricsOps type
Value members
Concrete methods
Wraps a Client with a middleware capable of recording metrics
Wraps a Client with a middleware capable of recording metrics
Same as apply, but can classify requests effectually, e.g. performing side-effects or examining the body.
Failed attempt to classify the request (e.g. failing with F.raiseError) leads to not recording metrics for that request.
- Value parameters:
- classifierF
a function that allows to add a classifier that can be customized per request
- client
the Client to gather metrics from
- ops
a algebra describing the metrics operations
- Returns:
the metrics middleware wrapping the Client
- Note:
Compiling the request body in
classifierFis unsafe, unless you are using some caching middleware.
