Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.
Install
sudo snap install node-exporter
Post-installation
The node-exporter snap requires some interfaces to be manually connected in order to grant permission to collect certain metrics. Without these connections, only basic metrics are available. To connect all exposed interfaces, run the following commands after installation:
sudo snap connect node-exporter:hardware-observe
sudo snap connect node-exporter:mount-observe
sudo snap connect node-exporter:network-observe
sudo snap connect node-exporter:system-observe
Configuration
Collectors can be enabled/disabled using the collectors and no-collectors configuration options with this snap. To specify multiple collectors, use a quoted string with space-separated values. For example:
sudo snap set node-exporter collectors=ntp
sudo snap set node-exporter no-collectors="mdadm netstat"
Reference the prometheus/node_exporter README.md: https://github.com/prometheus/node_exporter/blob/master/README.md#collectors for the list of collectors enabled by default.

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 node-exporter, simply use the following command:
sudo snap install node-exporter --beta
Browse and find snaps from the convenience of your desktop using the snap store snap.
