For slow exporters, you may prefer to run the export on a 15-minute schedule (e.g. from cron) and write the results into a file which is picked up by node_exporter's textfile-collector.
The client(s) then scrape the metrics from node_exporter as normal, and get an immediate reply with the most recent data. node_exporter also gives additional metrics including the timestamp on the file, so you can alert if the process which writes the file has not updated them for too long. -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
