node-exporter (also written as node_exporter) is a prometheus exporter for hardware and OS metrics on *NIX kernels. It allows operators to have introspection into the relative health of the fleet of machines and to build dashboards and automated actions.
While prometheus does provide pre-built binaries for a number of kernels and architectures, they are only distributed as tarballs.
In the spirit of consistency, we decided to script the installation procedure for node-exporter so that we can have a repeatable setup across all of our machines. This script can also be used to upgrade and downgrade node-exporter to any version available on prometheus' node-exporter repository.
For the time being, the script is available as a gist. Please send in improvements and bugfixes.
For one-off installs, you can pipe the script directly to a shell.
