Platform Telemetry
cAdvisor
A daemon-level resource monitor that meticulously tracks hardware utilization to prevent container exhaustion.
cAdvisor provides deep container-level transparency for resource allocation and bottleneck detection. STD.DEV relies on it to meticulously track CPU, memory, and network utilization across the entire web cluster, ensuring that intensive operations like headless SSR rendering never trigger Out-Of-Memory (OOM) kills or CPU throttling.
Preventing Resource Exhaustion
The SCORE architecture relies heavily on high-concurrency microservices, such as the headless Chromium instances used for Server-Side Rendering (SSR) and Genkit RAG embedding pipelines. These services can experience massive, sudden spikes in memory and compute demands. cAdvisor operates natively at the Docker daemon level, continuously scraping cgroup data. It feeds this telemetry into Prometheus, allowing our orchestration layers to proactively balance loads and providing us with the transparent metric data needed to continually optimize our container resource limits for maximum cost-efficiency.
Infrastructure Telemetry Pipeline
To paint the complete observability picture, cAdvisor does not operate in isolation. While Blackbox Exporter confirms that a service is reachable over the network and Tempo traces the application logic, cAdvisor answers why a service might be failing internally. The raw hardware metrics are scraped by Prometheus, stored for long-term analysis in Mimir, and visualized centrally in Grafana. This continuous pipeline allows STD.DEV to correlate a sudden drop in website performance directly to a CPU throttling event or a memory leak within a specific Docker container, triggering proactive alerts before the hardware limits are completely exhausted.
