Hi Guys,
I am fairly new to Linux and New to ELK.
I followed the guide outlined here : https://www.digitalocean.com/community/tutorials/how-to-install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-7
I added my DNS servers, (1 master and 3 slaves) and everything worked fine for a while, but now I am getting this error in logstash.log.
{:timestamp=>"2016-08-09T14:18:09.038000-0700", :message=>"Beats input: the pipeline is blocked, temporary refusing new connection.", :reconnect_backoff_sleep=>0.5, :level=>:warn}
This is happening for filebeat,topbeat and syslog, so I do not think it is a configuration issue.
Any help would be greatly appreciated.
I can paste log files if you let me know what files or excerpt from files would be useful.
Nothing shows up in Kibana from the date of the first error. Just says No Results found.
