Expected Behavior

Notification in WebUI.

Current Behavior

Only logged in system logs. Need to proactively check logs for the issue.

Possible Solution

Notification under overview

Steps to Reproduce (for bugs)

  1. Create CSV parsing (i.e Exchange SMTP logs)
  2. Wait for it to gather some logs
  3. Check server's log for ERROR: org.graylog2.plugin.inputs.Extractor - Could not apply converter [csv] of extractor [a8f941c0-4f7e-11e6-bded-005056ae6767].


So this is just an improvement suggestion for when CSV parsing fails like this:

Would be nice to be notified to adjust or change extractor without having to "tail" the server logs to spot those issues (I guess Graylog could stream it's own logs and alert, as a workaround)
Not much impact except losing those badly structured logs.
