<h1 class="topictitle1">Why Do Metrics Fluctuate Significantly (Disk Read/Write Speed, Average Disk Read/Write Time, and CPU Usage)?</h1>

<div id="body0000002106620465"><p id="kafka-faq-0063__p1989232549">Metrics including <strong id="kafka-faq-0063__b180711278344">Disk Read Speed</strong>, <strong id="kafka-faq-0063__b1688593019349">Disk Write Speed</strong>, <strong id="kafka-faq-0063__b10273133317341">Average Disk Read Time</strong>, <strong id="kafka-faq-0063__b240116366340">Average Disk Write Time</strong>, and <strong id="kafka-faq-0063__b9738133873415">CPU Usage</strong> output instantaneous values. These metrics are for reference only. Generally, flushing Kafka data asynchronously to disk consumes disk I/O and CPU usage, causing fluctuations. They do not affect services.</p>
