How To Monitor CPU Use on DigitalOcean Droplets

DigitalOcean is a cloud hosting company that offers a variety of services, including Droplets, which are virtual machines that can be used for a variety of purposes. It is essential to monitor the CPU usage of an application operating on a Droplet to ensure that it runs smoothly and efficiently. This article will demonstrate how to monitor CPU utilization on DigitalOcean Droplets.

Step 1: Install and Configure a Monitoring Tool

Installing and configuring a monitoring tool on a DigitalOcean Droplet is the first stage in monitoring CPU usage. Several monitoring applications are available, such as Nagios, Zabbix, and Monit. This article will use Monit as an illustration.

Connect to your Droplet via SSH and execute the following commands to install Monit:

sudo apt-get update
sudo apt-get install monit

Once Monit has been deployed, it must be configured. The location of the configuration file is /etc/monit/monitrc. In a text editor, open the file and make the following modifications:

set daemon 120
set logfile syslog facility log_daemon
set idfile /var/lib/monit/id
set statefile /var/lib/monit/state

These configurations configure Monit to execute every 120 seconds and log its output to syslog.

Step 2: Configure Monit to Monitor CPU Usage

Following the installation and configuration of Monit, the next stage is to configure it to monitor CPU usage. Add the following lines to the end of the /etc/monit/monitrc file to accomplish this:

check system $HOST
    if cpu usage > 90% for 5 cycles then alert

These lines configure Monit to monitor CPU utilization every 120 seconds (the interval we set in Step 1). If CPU utilization exceeds 90% for five cycles (600 seconds), Monit will dispatch an alert.

Step 3: Test the Configuration

After configuring Monit to monitor CPU consumption, it is essential to test the configuration to ensure that it is functioning properly. To accomplish this, use the following command:

sudo monit monitor cpu

This command instructs Monit to promptly check the CPU usage and send an alert if it remains above 90% for 5 cycles.

Conclusion

Monitoring CPU utilization on DigitalOcean Droplets is essential for ensuring that your applications are operating efficiently. By installing and configuring a monitoring utility such as Monit, it is simple to monitor CPU usage and receive alerts if it exceeds a specified threshold. You should be able to easily monitor CPU usage on your DigitalOcean Droplets if you follow the methods outlined in this article.

Additional Tips

Here are some additional monitoring strategies for CPU usage on DigitalOcean Droplets:

• Utilize a remote monitoring service such as New Relic to monitor the CPU utilization of your Droplet via a web interface.
• Consider configuring alerts for additional system metrics such as memory utilization, disk utilization, and network traffic.
• Utilize a tool for load testing, such as Apache JMeter, to simulate heavy traffic on your application and monitor CPU utilization throughout the test.
• Examine the server logs frequently to identify CPU usage patterns and anomalies.

Final Thoughts

Monitoring CPU usage on DigitalOcean Droplets is essential for ensuring that your applications run smoothly. Using a monitoring tool such as Monit, you can easily monitor CPU usage and receive alerts if it exceeds a predetermined threshold. By implementing the steps indicated in this article and a few additional recommendations, you can ensure that your Droplets are operating efficiently and effectively.

Review your monitoring configuration frequently to ensure it is up-to-date and accurately reflects the performance of your application. By keeping a close watch on your Droplet’s CPU utilization, you can identify problems before they become critical and ensure that your users have the best experience possible.
