In this blog post, we&rsquo;ll explore their usefulness, and discuss how to monitor them using Netdata for both bare-metal servers and VMs.</p> <!-- truncate --> <h2 id="what-are-interrupts">What are Interrupts?</h2> <p>Interrupts are signals generated by hardware devices to indicate that they require attention from the CPU. Hardware devices can generate interrupts for a variety of reasons, including data transmission or reception, input/output operations, and other activities. When an interrupt is generated, the CPU stops what it is doing and handles the interrupt. Interrupts can have a significant impact on system performance, especially if there are a high number of interrupts occurring.</p>
