How to use it

  1. Read what 413 means before changing a retry loop.
  2. Check the common causes against the response body and the server log.
  3. Follow the retry note. Retrying a 400 with the same body will fail again.
  4. Alert only in the cases the verdict describes.

About this tool

HTTP 413 Content Too Large means The request body is bigger than the server allows. Servers send it when An upload or JSON payload exceeds the limit.

Common causes: A file that is too big or a payload limit on a proxy. The practical fix is: Send less data or raise the limit where the request is supposed to be large.

Retry: Do not retry the same body.

Alert on it? Usually no. Alert if a normal payload starts being rejected after a proxy change.

Trigv is a push for the moment a status starts mattering, not a log of every response. If the code is one you should hear about, the snippet posts a single event with level error or warning. The status page itself does not call your API.
