That doesn't sound right, those two should run on the ES/Postgres nodes. Only things like the blackbox exporter and snmp exporter should be considered for running beside Prometheus. > When I have time, my plan is to write a small HTTP server that spawns plugin as subprocesses that emit their metrics via stdout, which seems like a much more reasonable, low-maintenance solution, and something node_exporter ought to support in the first place. We went with the textfile collector approach, rather than reinventing cron.
