After upgrading Kibana 7.17.6 to 8.12.2, Kibana does not logs. Why? There were no problems before the migration. The indexes were downloading. ---

Hi, in In Kibana 7.17.6 I collected logs correctly. After upgrading to version 8.12.2, the logs do not appear. What's the problem. I'm downloading logs from an application on IIS. ```auto "Logging": { "Serilog": { "WriteTo": [ //useful for debugging //{ "Name": "Console" }, { "Args": { "nodeUris": "http://192.168.0.8:9200/", "indexFormat": "logstash-log-{0:yyyy.MM.dd}" } } ] } }, ``` ---

In journalctl -u logstash.service ```auto [logstash.outputs.elasticsearch][main] Failed to perform request {:message=>"Connect to localhost:9200 [localhost/127.0.0.1] failed: Connection refused", :exc> [logstash.outputs.elasticsearch][main] Attempted to resurrect connection to dead ES instance, but got an error {:url=>"http://localhost:9200/", :exception=>Lo> ``` ---

Some guesses: If you upgraded to ES 8.12.2, it might be secured by default. Using https instead of http so `http://192.168.0.8:9200` might be wrong. Also you may have to provide somewhere a login and password or the api key. I'd check serilog documentation to learn what you need to do when upgrading ES. I guess also you are talking about the Elasticsearch upgrade, right? Not specifically Kibana upgrade. I moved the discussion to #Elasticsearch as the endpoint is Elasticsearch... ---

Hi, in kibana 7 there was a logging.dest setting and logs from serilog were visible in kibana 7, after upgrading to kibana 8 no logs are visible, logging.dest is no longer in the configuration file. So how can we make the patterns visible again and load into the kibana 8? ---

You have to fix the logstash error. ---
