Hello!

Brand new to the Elasticstack, I have a question about date filtering. Here's the sample message:

`May 3 14:08:41 foo-hostname com.apple.xpc.launchd[1] (com.apple.preference.displays.MirrorDisplays): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.`

Here's the filter from my yml file:

```
filter {
  grok{
    match => ["message", "%{SYSLOGTIMESTAMP:syslog_timestamp} %{SYSLOGHOST:syslog_hostname} %{GREEDYDATA:syslog_message}"]
  }
  date {
    match => ["syslog_timestamp", "MMM dd HH:mm:ss"]
  }
}

```

It's giving me a dateparsefailure tag and I can't seem to figure out why...

Thanks!

Tim

You use "dd" in your pattern but the day of month (3) is only one character long. You need to list two patterns in your filter; one with "dd" and one with "d".
