motidivya-dlogs 0.1.15

dLogs - one command installer/bootstrapper for your logging & monitoring stack

dLogs: The "1-Click" Observability Stack

Monitor Everything. Host systems, Docker containers, Nvidia GPUs, and app logs. All in one place.

dLogs is a pre-configured, high-performance observability stack built on top of the industry-standard LGTM stack (Loki, Grafana, Telegraf/Promtail, Monitoring/Prometheus), enhanced with automatic dashboard provisioning and Python integration.

🚀 Features

• ⚡ Instant Setup: Install via pip or Docker.
• 🖥️ OS-Aware Host Visibility: CPU, RAM, disk, and network metrics across Windows, Linux, and fallback environments.
• 🐳 Docker Stats: CPU/Memory/Network per container (powered by cAdvisor).
• 🎮 Nvidia GPU Monitoring: realtime usage, temperatures, and power draw via host-side nvidia-smi or Docker's Nvidia runtime.
• 📜 Centralized Logging: Logs from your Python apps + Docker logs in one queryable UI.
• 🐍 Python SDK: dlogs wrapper to start logging in 2 lines of code.

💿 Installation

Option 1: Python (Recommended)

Install using pip (or pipx for isolation):

pip install motidivya-dlogs

Then initialize and start the stack:

# Create a folder for your stack
mkdir my-stack
cd my-stack

# Initialize configuration
dlogs init .

# Start the stack
dlogs up .

dlogs init auto-detects the host OS and writes .env with DLOGS_LOG_DIR for Docker Compose:

• Windows: C:/Logs
• Linux/macOS: ~/dlogs

If you want a custom path, set DLOGS_LOG_DIR yourself before running dlogs up ..

GPU monitoring is auto-enabled only when an Nvidia runtime is detected. You can force it on or off with DLOGS_ENABLE_GPU=1 or DLOGS_ENABLE_GPU=0.

Option 2: Docker

Run the CLI container directly:

docker run --rm -it \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v $(pwd):/app/work \
  divyesh1099/dlogs up /app/work

Option 3: Installer Script (Windows)

🐍 Python Integration (dLogs SDK)

The dlogs package includes a zero-dependency wrapper to send logs directly to this stack.

Usage:

from dlogs import dLogs

# Initialize (Auto-detects the right log dir for your OS)
logger = dLogs("my_super_app")

# Log normal info (Shows in Loki/Grafana)
logger.log("Application started successfully.")

# Log errors (Highlights in Red)
try:
    1 / 0
except Exception as e:
    logger.alert(f"Critical math failure: {e}")

How it works:

• It writes structured JSON logs to C:/Logs/app_name.json on Windows or ~/dlogs/app_name.json on Linux/macOS.
• You can override the location with DLOGS_LOG_DIR.
• Promtail (running in Docker) watches that folder.
• It scrapes the new lines instantly and sends them to Loki.
• You view them in Grafana Explore ({job="varlogs"} |= "my_super_app").

📊 Dashboards Guide

Grafana comes pre-provisioned. Go to http://localhost:3000/dashboards (admin/admin) and open the dLogs folder.

1. 🖥️ Host System Metrics

• Real-time CPU/RAM: Total system usage.
• Network I/O: Upload/Download speeds.
• Disk Usage: Filesystem usage for the active host.
• Requirements: Windows uses windows_exporter on port 9182, Linux uses the built-in dLogs host exporter on port 9100, and other OSes fall back to the bundled node-exporter container.

2. 🐳 Docker Containers

• CPU/Memory per Container: identify resource hogs.
• Network Traffic: See which container is chatting the most.
• Requirement: cadvisor container running.

3. 🟢 Nvidia GPU

• Usage %: Graphics load.
• VRAM: Memory allocation.
• Temp/Power: Thermal monitoring.
• Requirement: Nvidia drivers plus either host-side nvidia-smi or a Docker Nvidia runtime.

4. 🪵 Loki Logs

• Search Engine: Query logs using LogQL.
• Filters: Filter by app name, log level (INFO/ERROR).
• Live Tail: See logs as they happen.

🛠️ Architecture

The stack runs completely locally using Docker Compose:

Component	Port	Purpose
Grafana	3000	The Dashboard UI. Access via http://localhost:3000.
Prometheus	9090	Time-series database for metrics.
Loki	3100	Log aggregation system (like Splunk/ELK but lighter).
Promtail	—	Log collector. Watches log folder and sends to Loki.
cAdvisor	8090	Container usage metrics (Google's official tool).
GPU Metrics	9835	Host-side Nvidia exporter or Docker nvidia_gpu_exporter, depending on runtime support.
Host Metrics	9100 / 9182	Native Linux exporter on 9100, windows_exporter on 9182, or node-exporter fallback.
Ntfy	8080	Notification server (publish/subscribe).

Prometheus target files under .dlogs-state/prometheus/ are generated by dlogs up to match the active OS/runtime.
