You can use a little script to write metrics to a textfile and pick them up with node_exporter's textfile_collector, and run it periodically (e.g. from cron).
The textfile_collector also exposes the timestamp when the file was last modified, so you can alert if it stops being updated. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
