Purpose

This text_collector is a customized version of the S.M.A.R.T. text_collector example from node_exporter github repo: https://github.com/prometheus/node_exporter/tree/master/text_collector_examples

Requirements

• Prometheus
• node_exporter
  • text_collector enabled for node_exporter
• Grafana = 6.2
• smartmontools = 7

Set up

To enable text_collector set the following flag for node_exporter:

• --collector.textfile.directory

To get an up to date version of smartmontools it could be necessary to compile it: https://www.smartmontools.org/wiki/Download#Installfromthesourcetarball

• check by executing smartctl --version

• make smartmon.sh executable

• save it under /usr/local/bin/smartmon.sh

To enable the text_collector on your system add the following as cronjob. It will execute the script every five minutes and save the result to the text_collector directory.

Example for UBUNTU crontab -e:

*/5 * * * * /usr/local/bin/smartmon.sh > /var/lib/node_exporter/textfile_collector/smart_metrics.prom

How to add specific S.M.A.R.T. attributes

If you are missing some attributes you can extend the text_collector. Add the desired attributes to smartmon_attrs array in smartmon.sh.

You get a list of your disks privided attributes by executing: sudo smartctl -i -H /dev/<sdx> sudo smartctl -A /dev/<sdx>
