How to read Metricbeat iowait time


(Grantcurell) #1

I'm diagnosing some performance issues with a high speed security sensor I'm running. I strongly suggest disk I/O is my culprit. Metricbeat's has really helped me get insight on my stack's performance, but I'm not actually sure how to interpret the iowait field. See attached screenshot - what is that telling me?

Let me know if my Google-foo has failed me. If there's a resource that explains all this I'm happy to go read.
