I'm very new to the complete ELK stack. I set up on a ESXI 6.5 a CentOS 7 (minimal installation) the ELK stack. Everything is working so far (I think so).
I used for that: http://www.tecmint.com/install-elasticsearch-logstash-and-kibana-elk-stack-on-centos-rhel-7/
Now I want to send my data from my synology to logstash. Synology has a very easy GUI where I can set up the IP-Adress, Port, RFC3164 Schema and transferprotocol. So I have set up everything like that.
On the Synology (for sending log files):
There is no firewall running on CentOS (because internal/test usage).
Then I created the following file:
First, let’s make a simple configuration file for Logstash + syslog, called logstash-syslog.conf.
Now my questions:
How can I see that Logstash is using that config?
What is about the filters?
How can I send the file into Kibana or Elasticsearch (everyhting is on the same server)
Kibana question: What is the Index pattern?
How can I update the Kibana + ElasticSearch + Logstash to the actual version?
I know some very basic questions. I would be thankful if someone writes some explanation and a little "dummie" guide, because I have googled but it's not so easy to finde content to basic questions.
Thanks for your help.
