Hello community,

Is there any way to know message size in `b` or `kb` or `mb` or any unit of digital info in logstash?  
eg: logstash get message `ABCDEFBADFASFD13241325POIYTUUBLABLABLA`  
How can we know that message size? Is that possible in logstash?  
Which plugin is suitable? appreciate any idea 🙏

Yes, it's helpful. @Badger Thanks man  
I use this code snippet  
`ruby { code => "event.set('log_size', event.get('message').bytesize)" }`
