Hi @Pravinsugi,
let me understand:
is it correct?
At first, next time, please share your samples in text format to avoid to rewrite all of them.
Then I suppose that you already extracted the two fields customerOrderNumber and Received_message_class, otherwise you have to extract them, but to help you in this I need of your sample logs in text format.
Anyway, you should run something like this:
<your_search>
| stats
dc(Received_message_class) AS Received_message_class_count
values(Received_message_class) AS Received_message_class
BY customerOrderNumber
| eval status=if(Received_message_class_cont=3,"OK","there are only the following Messages: ".Received_message_class
| table customerOrderNumber status
Ciao.
Giuseppe
