Lager (as in the beer) is a logging framework for Erlang. Its purpose is to provide a more traditional way to perform logging in an erlang application that plays nicely with traditional UNIX logging tools like logrotate and syslog.
- Finer grained log levels (debug, info, notice, warning, error, critical, alert, emergency)
- Logger calls are transformed using a parse transform to allow capturing Module/Function/Line/Pid information
- When no handler is consuming a log level (eg. debug) no event is even sent to the log handler
- Supports multiple backends, including console and file. More are planned.
