I’m total newbee in Graylog/ES stuff. Using Kibana I downloaded some test data to see how its visualisations work (https://www.elastic.co/guide/en/kibana/current/tutorial-load-dataset.html)
Can I do smth similar with Graylog?
Also I would like to try downloading test data sample that is stored in Postgres now, say 10-100 rows from one table to see how I can visualize them with Graylog dashboards. With that small data sample I can do it manually, without configuring plugins or whatever, but can’t figure out how.
Actually I used this article https://www.elastic.co/guide/en/logstash/current/plugins-inputs-jdbc.html to load sample data to logstash. There were no error messages or any feedback. But after that I can’t find out whether this was successful and can’t find the way to visualize it on the dashboard. So it’s not clear what to do next.
Graylog requires the data it visualizes to be ingested by Graylog.
So you can basically take any data source (log stream, flat files, databases, message brokers such as RabbitMQ or Apache Kafka), send their data to Graylog (e. g. using Logstash, Filebeat, Syslog, whatever), and then use Graylog to visualize the data using dashboards.
Also, please take a look at the Getting Started Guide and the Dashboards documentation:
Getting started tutorial shows the example with syslog. Is it necessary to try it or it’s just an example? Anyway I tried and unfortunately I had no messages and checking in ‘If You Don’t Have Messages’ didn’t help me. Basically I can’t understand how to check whether loading by command like
