CephFS exporter

Prometheus exporter for CephFS metrics. Currently exposed metrics:

• cephfs_subvolume_quota_bytes for all subvolumes of all CephFS volumes
• cephfs_subvolume_used_bytes for all subvolumes of all CephFS volumes
• cephfs_subvolumegroup_quota_bytes for all subvolumegroups of all CephFS volumes
• cephfs_subvolumegroup_used_bytes for all subvolumegroups of all CephFS volumes

Build

make build

Usage

Run, optionally specify address/port where to listen for requests:

./cephfs_exporter -web.listen-address :9939

cephfs_exporter is using the default ceph configuration file in /etc/ceph/ceph.conf. If ceph management commands work correctly the exporter should also work.
