Introduction

Hey readers! Welcome to our ultimate guide on "psensor temp alarm script example." Whether you’re a seasoned pro or just starting out with system monitoring, this article has got you covered. We’ll delve deep into the world of psensor and guide you through creating effective temperature alarm scripts that will keep your system running smooth as butter.

What is psensor?

psensor is a versatile command-line tool that monitors hardware sensors on Linux systems. It provides real-time information on temperature, fan speed, voltage, and other critical parameters. With its powerful scripting capabilities, psensor empowers you to automate system monitoring and trigger alarms based on predefined thresholds.

Creating a psensor Temp Alarm Script

Step 1: Install psensor

Before you can start scripting, make sure psensor is installed on your system. Open your terminal and run the following command:

sudo apt-get install psensor

Step 2: Write the Script

Now, let’s dive into writing the actual script. Here’s a basic example that triggers an alarm when the CPU temperature exceeds 75 degrees Celsius:

#!/bin/bash

# Get the CPU temperature in degrees Celsius
cpu_temp=$(psensor -g temp1_input)

# Check if the temperature exceeds the threshold
if [ $cpu_temp -gt 75 ]; then
  # Trigger the alarm
  echo "CPU temperature is too high: $cpu_temp C"
  # Replace this command with your desired alarm action (e.g., email, sound alert)
  exit 1
fi

Step 3: Make the Script Executable

To make your script executable, run the following command:

chmod +x temp_alarm_script.sh

Step 4: Run the Script Periodically

To run your script periodically, you can use a cron job. Here’s an example that runs the script every 5 minutes:

crontab -e

# Run the script every 5 minutes
*/5 * * * * /home/user/temp_alarm_script.sh

Advanced Scripting Techniques

Using Arguments for Dynamic Thresholds

You can enhance your script by allowing users to specify custom temperature thresholds. Modify the script as follows:

#!/bin/bash

# Get the threshold from the command-line argument
threshold=$1

# Get the CPU temperature in degrees Celsius
cpu_temp=$(psensor -g temp1_input)

# Check if the temperature exceeds the threshold
if [ $cpu_temp -gt $threshold ]; then
  # Trigger the alarm
  echo "CPU temperature is too high: $cpu_temp C"
  # Replace this command with your desired alarm action
  exit 1
fi

Sending Email Notifications

To receive email notifications when the alarm is triggered, modify the script as follows:

#!/bin/bash

# Send an email notification
echo "CPU temperature is too high: $cpu_temp C" | mail -s "CPU Temperature Alarm" your_email@example.com

Table of Threshold Ranges

Sensor Threshold Range
CPU 60-80°C
GPU 70-90°C
Hard Drive 30-45°C
System Board 40-55°C

Conclusion

That’s it, readers! You’re now equipped with the knowledge to create custom psensor temp alarm scripts that will keep your system running optimally. Don’t forget to check out our other articles for more system monitoring and automation tips. Happy scripting!
