Overview

A matcher which matches exceptions if the request is from a local IP. The IPs which constitute a "local request" are those which match any of the following:

[/^127\.0\.0\.\d{1,3}$/, "::1", /^0:0:0:0:0:0:0:1(%.*)?$/]

If there is no request information found in the exception event data, then it will not match.

This matcher expects the IP to be accessible at event.to_hash[:request][:remote_ip], though this is configurable. Examples of usage are shown below:

app.match :local_request

With a custom IP field:

app.match :local_request, :remote_ip_getter => lamdba { |event| event.to_hash[:remote_ip] }
