Thanks for your contribution. It looks like some of the tests are failing though.

Thanks for your contribution @firerain-fd, this looks good.

Could you confirm that you've tried this out with the use cases you think you'd use it for and that is fulfills those needs? Gives us some extra confirmation beyond whatever is in our test suite.

Other than that, I'm not going to merge this yet as we've been rather lax with actually releasing all the pent-up change in our main branch for a while and that's some admin I need to work through when I get the time to sort it out. Once things are prepped for a new release, then I'll merge this and we can look at finally shipping a new version.

Yes, I checked this in my project. Now I can get an exception when it is impossible to connect to statsd server or when I fail to send a request.
