Disable NewRelic logs when running rake task on Heroku

Question

I have NewRelic plugged into my app, and whenever I run a rake task on Heroku I get the following output as part of the logging. There doesn't seem to be anything particularly informative or actionable in it (aside from maybe setting up SSL at some point) so I was wondering what's the best way to disable this from outputting every time I run rake.

You could change the New Relic log_level in your newrelic.yml file or via an environment variable (NEW_RELIC_LOG_LEVEL). The levels, in descending order of verbosity, are:

• debug
• info
• warn
• error
• fatal
