What Metrics Are Exported?

• zfs_health (enum): Represents the device's health, can be online, degraded, faulted, offline, available, unavailable and removed. The state is stored in the state label, and the value is 0 for not-in-state, and 1 for in-state.
• zfs_read_errors (int counter): The amount of read errors for this device.
• zfs_write_errors (int counter): The amount of write errors for this device.
• zfs_checksum_errors (int counter): The amount of checksum errors for this device.
• zfs_disk_count (int counter): The amount of disks in this pool or vdev.
• zfs_vdev_count (int counter): The amount of vdevs in the pool.
• zfs_spare_count (int counter): The spare amount in the pool.
• zfs_raw_size (int counter): The raw size (in bytes) of the device. This is not the actual capacity.
• zfs_capacity (int counter): The capacity (in bytes) of the device.
• zfs_available (int counter): The available bytes of the device.
• zfs_read_operations (int counter): The amount of read operations on this device.
• zfs_write_operations (int counter): The amount of write operations on this device.
• zfs_read_bandwidth (int counter): The read bandwidth for this device in bytes per second.
• zfs_write_bandwidth (int counter): The write bandwidth for this device in bytes per second.

Note: the zpool status commands use 1024, not 1000.

There are some common labels for the metrics:

• device_name: The name of the device that this metric is related to.
• device_type: The type of the device. Can be pool, vdev or disk.
• pool: The ZFS pool that this device (vdev or disk) is a part of.
