Reducing Noise

Honeybadger can ignore frequent/unwanted errors in order to reduce noise, limit bandwidth usage, or both.

Note: If you’re uploading a source map (recommended!) be sure to check out Improving error grouping and linking to source code.

Ignoring errors

To ignore an error, return false from any Honeybadger.beforeNotify handler:

Honeybadger.beforeNotify(function(notice) {
  if (/third-party-domain/.test(notice.stack)) { return false; }
});

The following notice properties are available in notice objects:

  • notice.stack - The stack trace (read only)
  • notice.backtrace - The parsed backtrace object
  • notice.name - The exception class name
  • notice.message - The error message
  • notice.url - The current url
  • notice.projectRoot - The root url
  • notice.environment - Name of the environment. example: “production”
  • notice.component - Similar to a rails controller name. example: “users”
  • notice.action - Similar to a rails action name. example: “create”
  • notice.fingerprint - A unique fingerprint, used to customize grouping of errors in Honeybadger
  • notice.context - The context object
  • notice.tags - A string comma-separated list of tags
  • notice.params - An object of request parameters
  • notice.session - An object of request session key/values
  • notice.headers - An object of request headers
  • notice.cookies - An object of cookie key/values. May also be sent as a string in the document.cookie “foo=bar;bar=baz” format.

The following additional notice properties are available in afterNotify handlers:

  • notice.id - The UUID of the error in Honeybadger

Limit bandwidth (browser only)

If your application is reporting too many errors (which could interfere with bandwidth constraints, or cause you to use up your monthly error volume too quickly), use the maxErrors configuration option:

Honeybadger.configure({
  // ...
  maxErrors: 20
});

On each page load, errors will be sent to Honeybadger until the maxErrors threshold has been reached. In the above example, 20 errors will be reported per page load.

Use Honeybadger.resetMaxErrors() to reset the counter between page loads (useful for single page apps which don’t typically reload the page often).
