LibreNMS-power-dash

Python code to extract and visualise power data collected from nLogic and APC pdu's via LibreNMS API

Power and Current Data Dashboard

This project consists of two main scripts: one for collecting power and current data from a LibreNMS server and storing it in a SQLite database, and another for visualizing this data using a Plotly Dash dashboard.

Prerequisites

Before you begin, ensure you have the following installed:

• Python 3.11 or later
• SQLite
• LibreNMS server with API access

Installation

Install the required dependencies using pip:

dash plotly pandas sqlite3

You can install these dependencies by running the following command:

pip install dash plotly pandas

Data Collection Script

The data collection script fetches power and current data from a LibreNMS server and stores it in a SQLite database.

Configuration

1. API Configuration:

   • Set the API_KEY and LIBRENMS_IP variables in the script to match your LibreNMS server details.

2. Running the Script:

   • Run the script using the command: python get_all_by_room.py

Features

• Fetches device IDs and their locations from the LibreNMS server.
• Collects sensor data for current and power.
• Stores the collected data in a SQLite database (power_data.db).

Dashboard Script

The dashboard script visualizes the data stored in the SQLite database using Plotly Dash.

Configuration

1. Database Configuration:

   • Ensure the SQLite database (power_data.db) is in the same directory as the script or provide the correct path.

2. Running the Dashboard:

   • Run the script using the command: python dash-power.py

Features

• Displays graphs for building totals and individual rooms.
• Allows selection of different time ranges (e.g., last 6 hours, last 1 day, etc.).
• Dynamically updates the legend values based on the zoom level.
• Accessible on external IP addresses.

Running the Dashboard

1. Start the Dashboard:

   • Run the script using the command: python dash-power.py

2. Access the Dashboard:

   • Open a web browser and navigate to http://127.0.0.1:8050/ to view the dashboard locally.
   • To access the dashboard on an external IP, ensure your network settings allow external connections and navigate to http://:8050/.

Accessing the Dashboard

• Local Access: http://127.0.0.1:8050/
• External Access: http://:8050/

Ensure that your firewall and router settings allow incoming connections on port 8050.
