• [nitpick] Consider revising the phrase 'shows by buckets' for clarity; for example, 'displays results in buckets of 100ms increments' would improve readability.

The command `opct adm parse-etcd-logs` reads the logs, aggregates the requests and shows by buckets of 100ms from 200ms to 1s.

[nitpick] Consider removing the redundant 'to' in 'help to troubleshoot'; using 'help troubleshoot' makes the sentence more concise.

Suggested change

	`opct adm parse-etcd-logs` is the utility to help to troubleshoot the slow requests in the cluster, and help make decisions like changing the flavor of the block device used by the control plane, increasing IOPS, changing the flavor of the instances, etc.
