Hi,

I have this sentence, `The deployment started 3/19/2019 at 2:05` as a `"message"` to logstash  
How do I capture the date and time in the above sentence? Also, how should I check to allow this sentence to be parsed and other sentences be ignored. I was thinking something on the lines of:

```
if [message] =~ /^The deployment started/ {
    ruby{
        <some code here to parse date and time>
    }
}

```

Any help here is appreciated. Thanks.

Why not a grok or dissect filter?

A dissect would be as simple as

```
dissect { mapping => { "message" => "The deployment started %{date} at %{time}" } }

```
