New Relic integration for Clojure
License: Other
This project exports one macro, com.climate.newrelic.trace/defn-traced. Use it as a
drop-in replacement for defn if you want calls to a function to show up in
New Relic transaction tracing.
To include in your project, add
to your lein dependencies.
General strategy adapted from Sean Corfield.
Hi, great use of macros!, just one little detail, I tried defn-traced but I didn't get the transactions in New Relic's dashboard so I tried the Sean Corfield's strategy and added the dispatcher parameter to the Trace annotation Trace {:dispatcher true} and it worked, so I guess something like defn-dispatcher with the dispatcher parameter set to true could be a workaround.
I'm not familiar enough with Clojure yet to know if maybe I've just misconfigured something, but locally, this macro works almost exactly as expected, a drop in replacement for defn (self referencing functions fail, but that's a limitation I can handle).
When I try to deploy the app to Heroku, I get an error on the line with "defn-traced" though: Can't define method not in interfaces: invoke, compiling:(file.clj:17:1)
I'm not sure why compiling ahead of time makes a difference here, but it happens locally as well.
