Recently we have been observing mysqld taking almost 200% CPU. We need to figure out what is causing this. So we installed Signoz. Will this help us? <#C01HWUTP4HH|>

You can start with collecting DB metrics using exporter.
<https://github.com/prometheus/mysqld_exporter>

Next step would be application instrumentation to get overview of the performance.
