Prometheus Scrape Config (K8s)

A set of Prometheus scrape configuration options.

Prometheus Scrape Config K8s is a workloadless Juju charm that acts as an adapter between metrics providers and Prometheus on Kubernetes. It intercepts scrape jobs from upstream charms and allows operators to override configuration options — such as scrape interval, timeout, relabeling rules, and sample limits — before forwarding them to Prometheus. It is a complementary charm to the Canonical Observability Stack (COS): https://documentation.ubuntu.com/observability

By interposing this charm between a scrape target and Prometheus, operators gain centralized control over scrape job settings without modifying the target charms themselves.

Key features:

• Override scrape job configurations (interval, timeout, proxy, relabeling) provided by upstream charms before they reach Prometheus.
• Configurable sample and label limits to control ingestion volume.
• Support for metric relabeling to filter, rename, or drop metrics at scrape time.
• Toggle forwarding of alert rules from upstream charms.
• Workloadless charm — no additional containers or resources required.
