Github user jpeach commented on the issue: https://github.com/apache/trafficserver/pull/996 My comments from [TS-4834](https://issues.apache.org/jira/browse/TS-4834) .. >I think the nomenclature should mirror the existing metrics which typically don't include "count" in the names. Especially since the count of bad disks (gauge) does not have the same semantics as the count of disk errors (counter). Looking at the code I think the bad disk metric is a counter not a gauge. > Is "disk" the right nomenclature, or would "span" be more accurate? How feasible is it to have separate metrics for read and write errors? Does it make sense to also have metrics for disk read and write operations, or are system tools sufficient for that? If you have a count of bad disks, does it make sense to have other disk counts? ie. good disks, offline disks, etc.
