This library implements the New Relic API and allows sending arbitrary metrics directly to their collectors from Erlang. New Relic is a paid "application monitoring" service.
You need to supply the metrics on the correct format. If you happen to
be using statman you can use the
included newrelic_statman transformer. It is fairly easy to
transform the metrics, so if you're using Folsom, estatsd or your own
tools, have a look at newrelic_statman to see how it's done.
Two application environment variables must be set in the newrelic app:
application_name: human readable name of the app, will show up in the web interfacelicense_key: secret license key
If you're using Statman and use the following conventions for naming your keys, you can use New Relic "for free".
{<<"/hello/world">>, {class, segment}}- Web transaction, class and segment can be anything and will show up in the "Performance breakdown"{<<"/hello/world">>, {db, <<"something">>}}- Web transaction with database access, will show up in the "Performance breakdown" as well as "Overview".
