Hi guys, I need to match the first line of each log and maybe store it in an array and prepend some metadata at the beginning of each line.. I have a grok pattern that's matching only the first result and ignores the rest.. how can I achieve this? btw, I don't know how many log lines this will have, it will be dynamic. ![image](https://us1.discourse-cdn.com/elastic/original/3X/3/c/3c35009225e50e35fcc8715f0741bd898920af8c.png) The grok pattern goes like this: "(?m)(?Writing table data)%{GREEDYDATA}" ---
