Good logging services?

Can anyone recommend good 3rd party logging services, a la Loggly? Kadira does a great job of logging console errors, but I’m looking for something that I can use for more detailed (and private) logging. What are some other options besides Loggly?

We use WInston with Papertrail and are quite happy with it. Have a look at: https://meteorhacks.com/logging-support-for-meteor/

I’ve had good success with https://trackjs.com/ and https://airbrake.io/
