Linux iostat metricset
Warning
This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.
The iostat module reports per-disk IO statistics that emulate iostat -x on linux.
Note
as of now, this data is part of system/diskio on Metricbeat, but can only be found in the Linux integration in Fleet. In the future, this data will be removed from system/memory.
For a description of each field in the metricset, see the exported fields section.
