[rabbitmq-discuss] lager vs sasl error log

[Tim Watson]

Hi all,

We've discussed moving to a different (non-standard) logging provider before, and I'll raise the issue again. Afaik we've not run into the issues with error_logger very often (i.e., the reasons why lager was invented, viz massive memory consumption due to serialisation of large terms in logging output). The 'filtering possibilities' with lager don't necessarily require the parse_transforms to be used iirc - you can submit a logging request direct to lager and specify the log level at the call site. Again, I'll raise the discussion with the rest of the team and let's see what comes of that.

Cheers,
Tim

Since rabbitmq (as far as I know) uses standard Erlang’s logging and since standard logs are redirected to lager, all rabbitmq related logs are processed by lager. Wihout many filtering possibilities though.
