I created this project to learn how to use the grok_exporter tool.
grok exporter's main goal is to parse lines from unstructed logs and send all the data to a processor that can
manipulate the data the way you want.
Why not use ELK? Well, not everyone has enough knowledge to run this stack. Also, some other companies invest more money in tools like Prometheus.
This project has three components:
- Apache web server (Apache)
- Web application (httpbin)
- grok exporter (grok_exporter)
Apache and grok share the same volume so the container running grok can find and parse the Apache access log file.
docker-compose up
We can make some requests to the web application.
If you wish to test with differentes routes you can read the httpbin docs.
