Apparently logs are transferred from Filebeat to logstash, however the filebeat logs continiously show this message:

2020-07-15T01:18:20.789Z INFO [monitoring] log/log.go:124 Non-zero metrics in the last 30s {"monitoring": {"metrics": {"beat":{"cpu":{"system":{"ticks":164920,"time":{"ms":37}},"total":{"ticks":1260130,"time":{"ms":282},"value":1260130},"user":{"ticks":1095210,"time":{"ms":245}}},"info":{"ephemeral_id":"8f755a57-1431-4a63-9a10-985fdbd764a2","uptime":{"ms":107460017}},"memstats":{"gc_next":4985264,"memory_alloc":3396320,"memory_total":376637838888}},"filebeat":{"events":{"active":-16,"added":186,"done":202},"harvester":{"open_files":1,"running":1}},"libbeat":{"config":{"module":{"running":0}},"output":{"events":{"acked":202,"active":-8,"batches":30,"total":194}},"outputs":{"kafka":{"bytes_read":3038,"bytes_write":81397}},"pipeline":{"clients":1,"events":{"active":3,"published":186,"total":186},"queue":{"acked":202}}},"registrar":{"states":{"current":1,"update":202},"writes":{"success":30,"total":30}},"system":{"load":{"1":0,"15":0.23,"5":0.1,"norm":{"1":0,"15":0.0575,"5":0.025}}}}}}

Hi!

The message you see is not an error message and it logs Filebeat's internal statistics. Since logs are being shipped to Logstash then Filebeat is properly configured.
