Custom otel collector

Setup for otel collector with components:

• SQL Query Receiver
• PostgreSQL Receiver

Prerequisites:

• docker
• go (version go1.22.6 works)

OpenTelemetry Collector Builder (ocb) will be downloaded as a part of makefile.

If your architecture is different than Linux (AMD 64), you need to change download link in the makefile

How to use?

1. Build and start with:

make run

2. Open http://localhost:3000
3. Log in with default credentials (admin/admin)
4. Query logs and metrics from database

What does it do

1. Builds custom otel collector with provided configuration
2. Starts following containers:
   • postgres with sample data
   • LGTM stack as observability backend
3. Collector periodically (according to the configuration) reads data from the database and produces otel signals - logs and metrics
