* Closes issue #261 on node_exporter. Delegated mdstat parsing to procfs project. mdadm_linux.go now only exports the metrics. -> Added disk labels: "fail", "spare", "active" to indicate disk status -> hanged metric node_md_disks_total ==> node_md_disks_required -> Removed test cases for mdadm_linux.go, as the functionality they tested for has been moved to procfs project.

* The netdev collector CLI argument `--collector.netdev.ignored-devices` was renamed to `--collector.netdev.device-blacklist` in order to conform with the systemd collector. #1279
|
||||
* The label named `state` on `node_systemd_service_restart_total` metrics was changed to `name` to better describe the metric. #1393
|
||||
|
||||
* Refactoring of the mdadm collector changes several metrics
|
||||
- `node_md_disks_active` is removed
|
||||
- `node_md_disks` now has a `state` label for "fail", "spare", "active" disks.
|
||||
- `node_md_is_active` is replaced by `node_md_state` with a state set of "active", "inactive", "recovering", "resync".
|
||||
|
