node-exporter

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.
