Whether you use one Compute Instance or dozens of them, mission-critical servers and services should be watched by an independent monitoring tool that can keep tabs on their availability.

You’ll be able to troubleshoot the problem and restore service as quickly as possible. Once set up, the tool actively watches your servers and services and alerts you when they’re unavailable.

Not everyone needs to monitor the availability of their server. Using an availability monitoring tool can help you rapidly detect and resolve service disruptions, thereby mitigating the impact on your websites and web applications. If you generate income from a blog or charge subscription fees for your web application, downtime can have a severe impact on your bottom line.

You’ll learn how to monitor the availability and performance of your system, manage your logs, and update your server’s software. This guide introduces the essential tools and skills you’ll need to keep your server up to date and minimize downtime.
