"Service is experiencing increased error rates" - Error rates increased from 0 to 100%

• slver 5y ago
  No service has 0% error rate, and 100% errors doesn't even mean much without context (you never receive all possible errors at once).
  • jfrunyon 5y ago
    Error rate = (number of requests which returned an error) / (total number of requests) You can choose plenty of time periods to satisfy a 0% error rate for most services - somewhere from milliseconds to days or even years.

  Or 50% error rates in case one of two nodes is down and you keep calling the faulty node. But the faulty node should not be called in a well designed system.

    But then you're serving 100% faulty. Error rates (as alert thresholds and end user reporting) are a service thing, not a node thing.
