Hello everyone, I am having the following log : Sun Dec 20 00:40:05 CST 2020: Starting docker, stream=prod, version=latest, pwd=PATH Processing... SERVER oc: Successfully processed 23 TSM servers. Failed: 23 Details: 1 (Host1): HTTP POST request failed, rc=500, null, msg=Internal Server Error 2 (Host2): TSM Server registration not found for hostname Host2 3 (Host3): HTTP POST request failed, rc=500, null, msg=Internal Server Error 4 (Host4): Index: 0, Size: 0 5 (Host5): TSM Server registration not found for hostname Host5 6 (Host6): HTTP POST request failed, rc=500, null, msg=Internal Server Error 7 (Host7): TSM Server registration not found for hostname Host7 Processing completed, elapsed time=896.59 seconds Sun Dec 20 00:55:05 CST 2020: Finished, rc=0 I need that somehow filebeats read just the events that start with a number but adds the first line of date to each one of them, for example: Sun Dec 20 00:40:05 CST 2020: Starting docker, stream=prod, version=latest, pwd=PATH 1 (Host1): HTTP POST request failed, rc=500, null, msg=Internal Server Error Sun Dec 20 00:40:05 CST 2020: Starting docker, stream=prod, version=latest, pwd=PATH 2 (Host2): TSM Server registration not found for hostname Host2 This since I need to extract every host event but with a date associated to it. Can you Help me please? Thank you Regards Kevin Scott Urbina Moreira ---
