Hi All,

Please find the below mentioned inputs

1. /abcd/efgh/yj/kl/mn/op
2. abcd/efgh/yj/kl/mn/op
3. abcd
4. /abcd
5. abcd/

Output Required: servicename = abcd

I have tried two grok parser

1. (/)?%{DATA:servicename}/ ==\> Making last / mandatory
2. (/)?%{DATA:servicename}(/)? ==\> Nothing is coming in servicename field

Can you please help me regarding the same?

Regards,  
Debashis

That is very strange!

You can use

```
grok { match => { "message" => "^(/)?(?<servicename>[^/]+)(/)?" } }
```
