I'm running out of ideas. Having the 6.2.1 stack installed (ES, Logstash, Kibana and X-Pack). As soon, as I start Filebeat on a host in order to forward syslog messages to the ELK stack, I do get
Caused by: org.logstash.beats.BeatsParser$InvalidFrameProtocolException: Invalid Frame Type, received: 1
errors in logstash logs.
I've disabled TLS. I've disabled filters. So the logstash config is down to the bare minimum:
input {
beats {
port => 5044
#ssl => true
#ssl_certificate => "/etc/pki/tls/certs/logstash-forwarder.crt"
#ssl_key => "/etc/pki/tls/private/logstash-forwarder.key"
}
}
output {
elasticsearch {
hosts => "localhost:9200"
manage_template => false
index => "%{[@metadata][beat]}-%{[@metadata][version]}-%{+YYYY.MM.dd}"
user => filebeat_internal
password => ***
}
}
Any help is greatly appreciated.
