 - `COSAgentProvider`: Use in machine charms that need to have a workload's metrics
   or logs scraped, or forward rule files or dashboards to Prometheus, Loki or Grafana through
   the Grafana Agent machine charm.
+  NOTE: Be sure to add `limit: 1` in your charm for the cos-agent relation. That is the only
