Hello, I'm new to Elastic, I just installed ELK Server, and I want to monitor errors 400 and 500. Is there a way to show the errors without having to filter manually every time with: `response : 400` Let's say I have 1 log file where I get a bunch of errors 400 and 500 coming from different hosts. Ideally, I would like to have a "list" with all that different hosts showing the 400 or 500 err. Thanks ---

Hi Ricard, I recommend to have a look at Alerting in Kibana Observability. You could use a Log Threshold rule on `response` field and grouping by `host.hostname` (see [documentation](https://www.elastic.co/guide/en/observability/current/logs-threshold-alert.html) for details). Hope that helps. ---
