For services that are scraped on multiple hosts/VMs (or any setup with more than one `instance` behind the same `job`/service label), this collapses everything into one number with no way to tell the targets apart.\n\nConcrete case: a service is scraped on two VMs (dev + prod). Both contribute to the same `job` label. The MCP returns one CPU curve and one memory curve, but no way to know which VM the value came from — or\n\n[Read the thread](https://github.com/ThoTischner/observability-mcp/issues/15) · 2026-05-01 · closed · 0 comments\n\n### Grafana Cloud (Mimir/managed Loki) Inkompatibilität: Health-Checks + listServices\n\n## TL;DR\n\nDrei Endpoints im Connector-Code zielen auf Pfade, die nur **Self-Hosted Prometheus/Loki** exponieren.
