Final diploma work of Slurm courses.

This project has the following services:

• api allows you to get, post raw information and get analyzed metrics;
• metrics_generator that generate fake metrics;
• db PostgreSQL
• otel-collector - collect trace_id
• tempo
• grafana - visualize spans

Project technologies

• FastAPI
• Python3.10
• Aiohttp
• Flask
• PostgreSQL
• Grafana
• Tempo
• OTLP instrumentation
• Docker, docker compose

Create .env file and set the following environmental variables, if you don't want to use default values:

Environmental	Description
SECRET_KEY	db secret key
POSTGRES_USER	db username
POSTGRES_PASSWORD	db password
POSTGRES_SERVER	db hostname (name of docker compose service)
POSTGRES_PORT	port for connection to db
POSTGRES_DB	db table

Running with docker compose

docker compose up -d

How it works

Swagger API: http://127.0.0.1:5000/docs

1. Get analyzed metrics: http://127.0.0.1:5000/analyzed_metrics/1, where last num - amount of data portion, the more, the longer request (you can see it in grafana)
2. Get trace_id in log in stdout
3. Paste trace_id in grafana http://127.0.0.1:3000/explore
4. See time of tracing network connections or/and sql queries.

For example: http://127.0.0.1:5000/api/analyzed_metrics/1 -> 187.85ms

http://127.0.0.1:5000/api/analyzed_metrics/10 -> 1.77s

Also, it works with database queries like http://127.0.0.1:5000/api/teams/1
