Hi!
We love graylog, thank you for making it available!!
Have setup an extractor to extract “ad_username” from authentication failures. Now we want to setup an alert for more than X authentication failures in a row, to alert the end user. So, as an alert recipeint, we are trying to use the extracted username, like: ad_username@company.com
However, the “ad_username” is kept, rather then being replaced by the actual username, so the email is sent to ad_username@company.com which of course does not work.
We tried: ${ad_username}@company.com, $${$ad_username}@company.com, {$ad_username}@company.com, etc, all with similar result.
Is what we are trying to do possible? FYI: graylog 2.4 (yes, we need to upgrade)
