I use Kibana, for a visualization I need a substring of my log.
Let say my log ist.
Lorem ipsum dolor BookID 465, orderID: 45, consetetur sadipscing elitr.
and another example
Lorem ipsum dolor BookID 12356468, orderID: 45, consetetur sadipscing elitr.
What is the correct script to extract 465 or 12356468. As you see the length of the IDs can be different.
