Grafana Alloy
Telemetry agents and gateway for tenant-aware logs and OpenTelemetry signals.
Component Category
Monitoring and debugging / telemetry collection
Component Description
Grafana Alloy is a telemetry collector that can gather, process, and forward logs, metrics, traces, and related signals.
Why It Is Used
In BullSequana AI Foundation, Alloy collects pod logs, applies tenant routing, and receives OpenTelemetry signals before sending them to the observability backends.

Deployment notes
Alloy v1.12.2 runs per node to collect pod standard output and error. It parses each log body as JSON and, when a non-empty top-level tenant_id is present, uses that value as the Loki tenant for that entry. Non-JSON logs and JSON entries without tenant_id use the platform fallback.
A separate Alloy gateway receives application telemetry over OTLP/gRPC and OTLP/HTTP. It sends traces to Tempo, metrics to Prometheus, and logs to Loki under the platform tenant. KServe controller and model-workload metrics are scraped by this gateway; KServe is not configured as a general OTLP trace or log source.
Interacts With
Grafana Loki, which receives tenant-partitioned log streams collected by Alloy.Grafana Tempo, which receives traces routed through the Alloy gateway.Prometheus, which scrapes Alloy metrics through the service monitor setup.- Kubernetes workloads across the platform, because Alloy runs as a daemonset and collects node and pod-level telemetry.
