Fluentd configuration for PHP errors

Lately, I have been working on centralizing the logs from all of our servers and application layers.  I decided to use Fluentd instead of Logstash because it claims better reliability without jumping through hoops (e.g. adding a kafka layer).

Anyways, working on the configuration, I noticed that it doesn’t have any default configs for PHP errors.  My quick google search didn’t reveal anything either.  So, I decided to write the regex myself.  Here is what I ended up with.  This also accounts for multiline stack traces.

 @type tail
 tag SERVERNAME.php.errors
