Introduction

Elastic Stack is fantastic at collecting and visualizing log events. Serilog is fantastic at producing structured log events. This repository provides a sandbox where developers can explore the life of a log event starting with its birth in Serilog, its transport over the network to Logstash, its fields being indexed by Elasticsearch and finally its legacy being recorded as a historical event in Kibana.

What you will end up with

With a running Elastic Stack and Serilog producing log events you are now ready to take it to the next level. If you fancy the producing part you'll dig deeper into Serilog and its configuration of log contexts, enrichers and message formatters. If you enjoy monitoring applications in production you'll explore Kibana with its visualizations and dashboards.

Requirements

• Docker

Usage

Bringing up Elastic Stack

Start the stack using docker:

cd .\elastic-stack\

# This command is only necessary the first time the stack is started
docker compose up setup

docker compose up

Publishing log events using Serilog

Run the following commands to publish log events to Logstash using Serilog:

cd .\serilog\
docker compose up

If you decide to run the application outside of Docker in your terminal, don't forget to change the request URI to http://localhost:31311. More information can be found in .\serilog\Program.cs.

Using Kibana to render the log events

Access the Kibana web UI by hitting http://localhost:5601 with a web browser, and when prompted enter username elastic and password changeme.
