Monitoring the health and uptime of your web server or web host is important. You want to make sure your website is always available to your users, and that your website isn’t slow. Server monitoring tools allow you to gather and analyze data about your web server.
There are many great server monitoring solutions out there. I thought of sparing you the trouble by curating the list of the best server monitoring tools I could find.
Editor’s note: The last time we covered server monitoring tools was in 2009. We thought it was time to revisit this topic and also discuss some newer tools.
