Prometheus
Prometheus is an open-source systems monitoring toolkit that pulls time-series metrics from instrumented targets over HTTP and stores them locally, offering its own PromQL language for querying and alerting.
Baseline topologies
| Topology | Minimum nodes | Roles |
|---|---|---|

| ha-scraper-pair | 2 | prometheus |
| remote-write-agent | 1 | prometheus-agent |
What drives the cost
- Local retention window (days)

- Active series (millions)
- Approximate active time series count handled by the deployment.
- Scrape targets
- Number of scrape targets polled on the configured interval.
