This is an example of application instrumented for Prometheus. By default it
listens on port 8080 and exposes metrics on the /metrics endpoint.
Set the CPU temperature metric:
curl http://localhost:8080/cpu -d 42.0
Increment the number of errors for the sda device:
curl http://localhost:8080/hd -d sda
$ ./instrumented_app --help
usage: instrumented_app [<flags>]
Flags:
--help Show context-sensitive help (also try --help-long and --help-man).
--listen="127.0.0.1:8080" Listen address
--listen-metrics="" Listen address for exposing metrics (default to 'listen' if blank)
--basic-auth="" Basic authentication (eg <user>:<password>)
