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:
- Give your error counter a name (e.g., "ganglia")
- Code up a type in Go that implements the ErrorCounter interface
- Modify errorcounter.go so that it recognizes your error counter.
- 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.
