The prometheus-iscsi-exporter snap exposes high level ISCSI metrics to Prometheus.
Metrics
Metrics are scrapped from the snap's $SNAP_DATA directory (/var/snap/prometheus-iscsi-exporter/current).
Multipath command output should be written to $SNAP_DATA/multipath.
Multipath Device Total
The total number of devices setup to use multipath. This is a gauge metric, and it is exported with the name
iscsi_multipath_device_total.
Multipath Number of Paths
The number of paths per device. This is a gauge metric, and it is exported with the name iscsi_multipath_path_total.
Each metric is labeled with the device's alias and wwid.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap can be installed from the command line on openSUSE Leap 15.x and Tumbleweed.
You need first add the snappy repository from the terminal. Choose the appropriate command depending on your installed openSUSE flavor.
Tumbleweed:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Tumbleweed snappy
Leap 15.x:
sudo zypper addrepo --refresh https://download.opensuse.org/repositories/system:/snappy/openSUSE_Leap_15.6 snappy
If needed, Swap out openSUSE_Leap_15. for, openSUSE_Leap_16.0 if you’re using a different version of openSUSE.
With the repository added, import its GPG key:
sudo zypper --gpg-auto-import-keys refresh
Finally, upgrade the package cache to include the new snappy repository:
sudo zypper dup --from snappy
Snap can now be installed with the following:
sudo zypper install snapd
You then need to either reboot, logout/login or source /etc/profile to have /snap/bin added to PATH.
Additionally, enable and start both the snapd and the snapd.apparmor services with the following commands:
sudo systemctl enable --now snapd
sudo systemctl enable --now snapd.apparmor
To install prometheus-iscsi-exporter, simply use the following command:
sudo snap install prometheus-iscsi-exporter
Browse and find snaps from the convenience of your desktop using the snap store snap.
