My input logs looks like:

* * *

## START the log printing 08/09/2019 10:12:45

## 43003|Thread1|20.3|33.4 34532|Thread2|73.5|75.5

## END the log printing 08/09/2019 10:13:05

Can anyone please provide the input filter with multiline codec

Note: In the above input logs the hypen is overirded with space

Try something like below in your input section.  
You only need to create regex to catch start of your block.  
In my case it's timestamp so i'm using pattern =\> "%{TIMESTAMP\_ISO8601}"

```
file {
	path => ["/path/to/your/file.log"]
	codec => multiline {
		pattern => "regex_matching_start_of_your_event"
		negate => true
		what => previous
	}
}

```

and then parse received message using grok if needed.
