Problem with log processing

Elastic Stack Beats
,
1

Version 7.6.2
Data is processed incorrectly. All dashboards are empty (I created a user for this, used sudo commands, and so on)
Configured filebeat as follows: filebeat - > Logstash - > Elasticsearch.
I tried different actions for issuing syslog in kibana and all without result.
Please help me with this problem :slight_smile:

Did you try to enable debug logging and verify step by step? I'm not sure if you're actually facing a problem with logstash not beats...

It doesn't work out of the "box" with the current settings?
