Kubernetes - Monitoring pod IO

Question

I would like to monitor the IO which my pod is doing. Using commands like 'kubectl top pods/nodes', i can monitor CPU & Memory. But I am not sure how to monitor IO which my pod is doing, especially disk IO.

Any suggestions ?

Answer 1

Since you already used kubectl top command I assume you have metrics server. In order to have more advanced monitoring solution I would suggest to use cAdvisor , Prometheus or Elasticsearch .

For getting started with Prometheus you can check this article .

Elastic search has System diskio and Docker diskio metrics set. You can easily deploy it using helm chart .

Part 3 of the series about kubernetes monitoring is especially focused on monitoring container metrics using cAdvisor. Allthough it is worth checking whole series.

Let me know if this helps.
