Prometheus
prometheus is... something? A data collector/aggregator?
we try to put node exporter on whatever devices we can find for monitoring/alerting.
configuration seems to be here: https://git.devhack.net/devhack/core-infra/src/commit/main/k8s/monitoring/prom-scrape-configs/scrape-configs.yaml & thereabouts
theoretically prometheus has federated mode where multiple prometheus instances can pull from eachother? not sure how useful that is
