An error counter is used to record the rate of errors generated by Chaos Monkey to an external system such as a metrics or alerting system.

Inside of Netflix, we use an error counter to record error counts to Atlas, our metric system¹.

If you wish to record the error counts with an external system, you need to:

1. Give your error counter a name (e.g., "ganglia")
2. Code up a type in Go that implements the ErrorCounter interface
3. Modify errorcounter.go so that it recognizes your error counter.
4. Edit your config file to specify your error counter.

¹Unfortunately, we are unable to release this error counter as open source. Our Atlas error counter communicates with a version of Prana that has not been released as open source.
