Error Level ​

Monitor the error level of the application, reports about the too high level.

Possible reasons:

  1. Bug(s)
  2. A crawler generated too many requests to invalid URLs

Plan ​

  1. Check logs
  2. Check errors on New Relic:
    1. Open errors on New Relic (for the incident period) incident example
    2. Check which type of errors has more occurrences ("Occurrences" column): error occurrences
    3. Open Error group summary for the most popular error type(s) and check request.headers.userAgent value from the "Attributes" list userAgent header value
    4. Act based on this information. It's usually enough to build a plan for next steps. If you think it's a noise - consider improving the app to avoid producing such noise.
