Caretta review
A focused, self-hosted way to visualize Kubernetes service interactions in Grafana.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Caretta is a lightweight, open-source Kubernetes tool for teams that need visibility into service-to-service network interactions without deploying a service mesh or adding application instrumentation. It uses eBPF to create a visual dependency graph, resolves Kubernetes entities and owners, and presents the result through a Grafana Node Graph dashboard. Caretta runs on Linux, is deployed with Helm, and is designed for self-hosted environments.
Its strongest fit is straightforward Kubernetes network mapping. The tool exposes network throughput metrics that work with Prometheus-compatible queries and supports a configurable polling interval, giving teams a focused view of service relationships and traffic. Grafana, Prometheus-compatible dashboards, VictoriaMetrics, and Helm provide a practical ecosystem around the core mapper. Optional persistent metric storage can extend visibility beyond an in-memory or short-lived view, while the published configuration supports adding VictoriaMetrics and Grafana components during installation.
Caretta suits teams that want an open-source service map with a relatively narrow operational purpose. It can show Kubernetes dependencies and network activity without requiring a service mesh or application instrumentation, but it is not positioned as a complete observability platform. The self-hosted deployment model also means teams need Linux infrastructure with a kernel version of 4.16 or newer and CO-RE support. Choose Caretta for focused Kubernetes service mapping, throughput metrics, and Grafana visualization; choose a broader observability platform when application, infrastructure, tracing, or wider operational coverage is required.
Caretta pros and cons
- Where it wins
- Maps Kubernetes service interactions with eBPF
- Helm installation with Grafana and optional VictoriaMetrics components
- Prometheus-compatible throughput metrics and configurable polling
- Where it doesn't
- Self-hosted deployment requires Linux infrastructure
- Requires Linux kernel 4.16 or newer with CO-RE support
- Narrower scope than full observability platforms
