Alarms and Alerts ensure you don’t miss critical system hardware temperature and fan speed-related issues.

All the temperatures are plotted in one graph.

In fact, Psensor will detect any supported hardware and report the temperature as text and over a graph, automatically.

Psensor is capable of showing remote server temperature and fan speed.

Show the temperature of the motherboard, CPU, GPU (Nvidia), and Hard Disk Drives.

That’s all! In this article, we explained how to use shell script to send alert emails to system administrators in case server memory (RAM) is running low. Once you confirm that it is working, define the actual values you would like to use.īelow is a screenshot showing a sample alert email.

Then keep on checking from the command line using the free command provided in the script. Tip: You can test if it is working as intended, set the bench mark value a little high to easily trigger an email to be sent, and specify a small interval of about 5 minutes. This means that the above script will be run after every 1 hour as long as the server is running. # ln -s -t /etc/cron.hourly/alertmemory.sh /etc/scripts/alertmemory.sh

# send email if system memory is running lowĮcho -e 'Warning, server memory is running low! Free memory: $free MB' | mailx -a '$file' -s '$subject' -r '$from' -c '$to' '$also_to'Īfter creating your script /etc/scripts/alertmemory.sh, make it executable and symlink to cron.hourly.

In this article, we will share a small but useful shell script to send an alert email to one or more system administrator(s), if server memory is running low. One of the critical components of a server is memory ( RAM), it greatly impacts on overall performance of a system. You can write scripts to help you keep up with what’s unfolding on a server. You can write scripts to automate tasks, for instance daily back ups, system updates etc create new custom commands/utilities/tools and beyond. This offers you a reliable and effective means of system administration. You can write commands in a file known as a shell script and execute them collectively. A powerful aspect of Unix/Linux shell programs such as bash, is their amazing support for common programming constructs that enable you to make decisions, execute commands repeatedly, create new functions, and so much more.
