Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per btrfs filesystem

Labels:

Label Description
filesystem_uuid TBD
filesystem_label TBD

Metrics:

Metric Dimensions Unit
btrfs.disk unallocated, data_free, data_used, meta_free, meta_used, sys_free, sys_used MiB
btrfs.data free, used MiB
btrfs.metadata free, used, reserved MiB
btrfs.system free, used MiB
btrfs.commits commits commits
btrfs.commits_perc_time commits percentage
btrfs.commit_timings last, max ms

Per btrfs device

Labels:

Label Description
device_id TBD
filesystem_uuid TBD
filesystem_label TBD

Metrics:

Metric Dimensions Unit
btrfs.device_errors write_errs, read_errs, flush_errs, corruption_errs, generation_errs errors

Alerts

The following alerts are available:

btrfs_allocated btrfs.disk percentage of allocated BTRFS physical disk space
btrfs_data btrfs.data utilization of BTRFS data space
btrfs_metadata btrfs.metadata utilization of BTRFS metadata space
btrfs_system btrfs.system utilization of BTRFS system space
btrfs_device_read_errors btrfs.device_errors number of encountered BTRFS read errors
