logmera 0.1.5

Self-hosted AI observability backend

🔭 Logmera

Self-hosted monitoring for AI applications

Log prompts, responses, and latency from your AI apps and view them in a simple dashboard.

What is Logmera?

Logmera is a self-hosted observability tool for AI / LLM applications.

It helps developers understand what their AI systems are doing.

Instead of printing logs to the console, Logmera stores:

• prompts
• responses
• model name
• latency

in a PostgreSQL database and shows them in a web dashboard.

Your data stays on your infrastructure.

Why use Logmera?

When building AI applications it becomes hard to know:

• what prompts were sent
• what responses were returned
• how long requests took
• which model was used
• when errors happened

Logmera helps you see and monitor all AI activity in one place.

Quick Start

1. Install

pip install logmera

---

2. Start PostgreSQL

You can use any PostgreSQL database.

Example connection string:

postgresql://username:password@localhost:5432/database

If you do not have PostgreSQL installed, you can run it with Docker.

docker run --name logmera-postgres \
-e POSTGRES_USER=postgres \
-e POSTGRES_PASSWORD=postgres \
-e POSTGRES_DB=logmera \
-p 5432:5432 -d postgres:16

---

3. Start Logmera

logmera --db-url "postgresql://postgres:postgres@localhost:5432/logmera"

Server starts at:

http://127.0.0.1:8000

---

Open the Dashboard

Open your browser:

http://127.0.0.1:8000

You will see your AI logs in the dashboard.

---

Python Example

Add Logmera to your AI code.

import logmera

logmera.log(
    project_id="chatbot",
    prompt="Hello",
    response="Hi there",
    model="gpt-4o",
    latency_ms=120,
    status="success"
)

Now the request will appear in the Logmera dashboard.

---

API Example

You can also send logs using the API.

curl -X POST http://127.0.0.1:8000/logs \
-H "Content-Type: application/json" \
-d '{
  "project_id":"my-app",
  "prompt":"Hello",
  "response":"Hi",
  "model":"gpt-4o",
  "latency_ms":95,
  "status":"success"
}'

---

API Endpoints

Method	Endpoint	Description
GET	/health	Health check
POST	/logs	Create log
GET	/logs	Get logs

---

Configuration

Example CLI:

logmera --host 127.0.0.1 --port 8000

Environment variables:
