It&rsquo;s easy to think that you can just choose the metric &ldquo;Disk Utilization&rdquo; and add a condition to alert when disk utilization crosses some threshold for some length of time (such as over 55% for 1 hour).</p> <h2 id="file-system-type-filter">File System Type Filter</h2> <p>Your first problem is that a Linux system has many types of file systems, even if it only has one disk. You probably want to alert when your root disk is running out of space; therefore, you need to filter out non-disk filesystems like <a href="https://en.wikipedia.org/wiki/Procfs">procfs</a> or tmpfs. Add a device filter to select exactly which devices you want to alert on; in my case, with only one disk per server, I match only on device rootfs.</p>
