I'm brand new to Logstash, I'm trying to get an Filebeats - LogStash - Elasticsearch pipeline set up using the online documentation. But I'm running into a problem where I get the following error:
[root@elastic-01 logstash]# /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/first-pipeline.conf --path.settings /etc/logstash
Sending Logstash's logs to /var/log/logstash which is now configured via log4j2.properties
log4j:WARN No appenders could be found for logger (io.netty.util.internal.logging.InternalLoggerFactory).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See Apache log4j 1.2 - Frequently Asked Technical Questions for more info.
While researching, it appears this error has popped up a NUMBER of times over time regarding logstash and even elasticsearch. I've read through the following posts and bug reports:
Here are my versions:
[root@elastic-01 logstash]# /usr/share/logstash/bin/logstash-plugin list --verbose beats
logstash-input-beats (3.1.12)
[root@elastic-01 logstash]# /usr/share/logstash/bin/logstash-plugin update logstash-input-beats
Updating logstash-input-beats
