Hi guys,

im a beginner in Elasticsearch and here is my problem. Below you can see the log, I want to get for instance the duration value which is given in seconds here, then I want divide it by 60 so I have the minutes. Can you please tell what pattern I need to match that and how to calculate with the values after that?

Thanks in advance
