Overview

If you are running a server or even multiple on your Raspberry Pi, constant monitoring is important to make sure everything is operating smoothly and not burning through your system's resources. This is normally done by SSHing into the system to make sure processes are running as expected, but this can be a bit tedious when you just want a quick glance at certain stats or are on another device and need authentication. PiPulse makes it easy to monitor your Raspberry Pi without the need to SSH every time.

(P.S: Although its called PiPulse, it can work on most Linux-based systems!)

How it Works

• A client-side CLI connects to the agent on the Raspberry Pi via the local network.
• They both use HTTP communication methods to send data to each other.
• When a command is ran on the client, it connects to the selected local IP and port (if it has the agent running).
• The agent uses psutils to send back system information to the client as json depending on the endpoint.
• The client then decodes the json and prints the information to the terminal.
• The data then gets inserted into the relevant tables in the SQLite database.

Features

• Gather a summary of system utilization.
• Recieve detailed memory and disk information
• Stores recorded data in a .db file using SQLite3

Client Setup

1. Go to the releases tab and download the latest pipulse-client.exe file.
2. Open the terminal in the same directory as the exe.
3. Go to Usage or run ./pipulse-client to view command list.

Usage

Example Session

Main Command Options

Option	Required	Description
./pipulse-client	YES	Runs the CLI
--host [HOST IP]	YES	Local IP of where the agent service is running
--port [port set in the pi-agent.py script]	NO	Local open port of where the agent service is running (default 8000)

Endpoints

After writing the main command, select an endpoint to give you the information you need.

Endpoint	Description	Arguments
stats	Provides summary of CPU, RAM, and disk utilization	None
disk	Provides disk space information and utilization	None
memory	Provides RAM capacity information and utilization	None
cpu	Provides CPU cores and core usages	--seconds: Length of recording interval (default 2)
