## Introduction

Modern computer vision (CV) systems need **end-to-end observability**: real-time resource and latency monitoring, distributed tracing across services, centralized logs, and long-horizon analytics. In this guide, we show how to monitor a CV pipeline with [**Amazon CloudWatch**](https://aws.amazon.com/cloudwatch/) and [**AWS X-Ray**](https://aws.amazon.com/xray/) (for inference latency, GPU/CPU/memory, and request traces), how to store historical metrics in [**MongoDB Time Series collections**](https://www.mongodb.com/docs/manual/core/timeseries-collections/), and how to surface insights in a React dashboard. We’ll also compare [**Prometheus**](https://prometheus.io/docs/concepts/metric_types/)/[**Grafana**](https://grafana.com/docs/grafana/latest/dashboards/) and [**Datadog**](https://docs.datadoghq.com/tracing/) options and share best practices specific to vision workloads. ([MongoDB](https://www.mongodb.com/docs/manual/core/timeseries-collections/), [Prometheus](https://prometheus.io/docs/concepts/metric_types/), [Grafana Labs](https://grafana.com/docs/grafana/latest/dashboards/), [docs.datadoghq.com](https://docs.datadoghq.com/tracing/))

## Key Metrics to Monitor in Computer Vision Systems

Effective monitoring starts with the right KPIs for ML on Kubernetes/EC2: **resource utilization** (CPU, memory, and **GPU**), **inference latency & throughput**, **model performance** (accuracy/precision/recall), **data/label drift**, and **error rates**. AWS’s ML observability guidance for EKS highlights these “golden signals” and stresses targeting high GPU utilization to avoid waste and contention. See [**Intro to observing ML on Amazon EKS**](https://aws.amazon.com/blogs/containers/part-1-introduction-to-observing-machine-learning-workloads-on-amazon-eks/) and [**EKS best practices for AI/ML observability**](https://docs.aws.amazon.com/eks/latest/best-practices/aiml-observability.html). ([Amazon Web Services, Inc.](https://aws.amazon.com/blogs/containers/part-1-introduction-to-observing-machine-learning-workloads-on-amazon-eks/), [AWS Documentation](https://docs.aws.amazon.com/eks/latest/best-practices/aiml-observability.html))

## Monitoring Resource Usage & Latency with Amazon CloudWatch

**GPU monitoring.** Install the [**CloudWatch agent with NVIDIA GPU support**](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-NVIDIA-GPU.html) to capture GPU utilization, memory, temperature, and power on EC2/EKS nodes. AWS also provides [**prebuilt solutions and dashboards for NVIDIA workloads**](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/Solution-NVIDIA-GPU-On-EC2.html) and Container Insights guides for GPUs on EKS. ([AWS Documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Agent-NVIDIA-GPU.html))

**Custom application metrics.** Publish inference timings and throughput as **custom metrics** so you can graph p50/p95/p99 and alert on SLOs. Example (Python): use `boto3` [**PutMetricData**](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/cloudwatch/client/put_metric_data.html) to send `InferenceLatency` with dimensions like model name/version. ([Boto3](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/cloudwatch/client/put_metric_data.html))

**Centralized logs.** Ship stdout or file logs to [**CloudWatch Logs**](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html) (or the [**Logs agent**](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AgentReference.html)) for search, retention, and alarms using Logs Insights/metric filters. ([AWS Documentation](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/WhatIsCloudWatchLogs.html))

## Distributed Tracing & Inference Logging with AWS X-Ray

Complex CV pipelines span preprocessing → inference → postprocessing → DB writes. [**AWS X-Ray**](https://docs.aws.amazon.com/xray/latest/devguide/aws-xray.html) traces each request end-to-end, with a **service map** and **timeline** to pinpoint bottlenecks and failures. See [**Viewing traces & details**](https://docs.aws.amazon.com/xray/latest/devguide/xray-console-traces.html) and [**Using the X-Ray trace map**](https://docs.aws.amazon.com/xray/latest/devguide/xray-console-servicemap.html). You can also correlate traces with metrics/logs via [**CloudWatch ServiceLens integration**](https://docs.aws.amazon.com/xray/latest/devguide/xray-services-cloudwatch.html). ([AWS Documentation](https://docs.aws.amazon.com/xray/latest/devguide/xray-console-traces.html))

**Correlate logs ↔ traces.** Include the X-Ray **trace ID** in your structured JSON logs to jump from an alarm to the exact request’s logs and trace. AWS’s observability series shows how to add trace IDs in logs: [**“.NET observability: logging”**](https://aws.amazon.com/blogs/modernizing-with-aws/net-observability-cloudwatch-aws-x-ray-part2-logging/). ([Amazon Web Services, Inc.](https://aws.amazon.com/blogs/modernizing-with-aws/net-observability-cloudwatch-aws-x-ray-part2-logging/))

## MongoDB for Pipeline Metrics & Long-Horizon Analytics

For month-over-month trends (accuracy, latency creep, error rates), store metrics in [**MongoDB Time Series collections**](https://www.mongodb.com/docs/manual/core/timeseries-collections/). Time Series offers **columnar storage, automatic time/metadata indexing, and reduced disk usage** versus regular collections—ideal for fast aggregations over large telemetry sets. See [**Benefits**](https://www.mongodb.com/docs/v7.0/core/timeseries-collections/) and [**Best practices**](https://www.mongodb.com/docs/manual/core/timeseries/timeseries-best-practices/). ([MongoDB](https://www.mongodb.com/docs/v7.0/core/timeseries-collections/))

## React Dashboard for Model Accuracy & Performance Trends

Expose a simple API (e.g., `/metrics`) that queries MongoDB for **accuracy, drift metrics, latency percentiles, usage, error rates, GPU utilization**. In React, render charts (e.g., via Chart.js/Recharts) and add filters (date range, model version, camera/site). This mirrors Grafana-style dashboards but tuned to your CV KPIs; for reference on dashboard patterns, see [**Grafana’s dashboard docs**](https://grafana.com/docs/grafana/latest/dashboards/). ([Grafana Labs](https://grafana.com/docs/grafana/latest/dashboards/))

## Alternatives: Prometheus, Grafana, and Datadog

**Prometheus + Grafana (open source / managed).** Expose Prometheus metrics (counters, gauges, histograms, summaries) from your services and scrape them with Prometheus; visualize in Grafana. See [**Prometheus metric types**](https://prometheus.io/docs/concepts/metric_types/) and [**PromQL basics**](https://prometheus.io/docs/prometheus/latest/querying/basics/). AWS offers managed options—[**Amazon Managed Service for Prometheus**](https://docs.aws.amazon.com/prometheus/) and [**Amazon Managed Grafana**](https://docs.aws.amazon.com/grafana/latest/userguide/what-is-Amazon-Managed-Service-Grafana.html)—plus EKS integrations. ([Prometheus](https://prometheus.io/docs/concepts/metric_types/), [AWS Documentation](https://docs.aws.amazon.com/prometheus/))

**Datadog (hosted, all-in-one).** Datadog unifies metrics, logs, and **APM traces** with GPU integrations (NVIDIA DCGM/NVML). See [**APM/Tracing**](https://docs.datadoghq.com/tracing/), [**DCGM integration**](https://docs.datadoghq.com/integrations/dcgm/), and [**Logs collection/parsing**](https://docs.datadoghq.com/logs/log_collection/). It’s a fast path to full-stack observability for CV workloads on EC2/EKS with GPUs. ([docs.datadoghq.com](https://docs.datadoghq.com/tracing/))

**OpenTelemetry/ADOT (vendor-neutral instrumentation).** Instrument once with [**OpenTelemetry**](https://opentelemetry.io/docs/specs/otel/overview/) and route to CloudWatch, X-Ray, Prometheus, or Datadog. On AWS, use [**AWS Distro for OpenTelemetry (ADOT)**](https://aws-otel.github.io/docs/introduction/) and its collectors/operators for EKS to ship metrics/traces to your chosen backend. See [**ADOT ↔ X-Ray**](https://docs.aws.amazon.com/xray/latest/devguide/xray-services-adot.html) and [**ADOT collector → AMP**](https://docs.aws.amazon.com/prometheus/latest/userguide/AMP-ingest-with-adot.html). ([AWS Distro for OpenTelemetry](https://aws-otel.github.io/docs/introduction/), [OpenTelemetry](https://opentelemetry.io/docs/specs/otel/overview/), [AWS Documentation](https://docs.aws.amazon.com/xray/latest/devguide/xray-services-adot.html))

## Vision-Specific Best Practices (Checklist)

- **Instrument everything**: GPU, CPU, memory, queue depths, per-stage timings; trace requests end-to-end. (See [**EKS ML observability essentials**](https://aws.amazon.com/blogs/containers/part-1-introduction-to-observing-machine-learning-workloads-on-amazon-eks/).) ([Amazon Web Services, Inc.](https://aws.amazon.com/blogs/containers/part-1-introduction-to-observing-machine-learning-workloads-on-amazon-eks/))
- **Track model health** continuously: log evaluation metrics and watch for drift; correlate with data changes/deploys. (Same EKS guidance.) ([Amazon Web Services, Inc.](https://aws.amazon.com/blogs/containers/part-1-introduction-to-observing-machine-learning-workloads-on-amazon-eks/))
- **Correlate metrics, logs, and traces** using a common **trace ID** in JSON logs for rapid RCA. (See [**X-Ray + CloudWatch ServiceLens**](https://docs.aws.amazon.com/xray/latest/devguide/xray-services-cloudwatch.html) and [**logging with trace IDs**](https://aws.amazon.com/blogs/modernizing-with-aws/net-observability-cloudwatch-aws-x-ray-part2-logging/).) ([AWS Documentation](https://docs.aws.amazon.com/xray/latest/devguide/xray-services-cloudwatch.html), [Amazon Web Services, Inc.](https://aws.amazon.com/blogs/modernizing-with-aws/net-observability-cloudwatch-aws-x-ray-part2-logging/))
- **Dashboards + alerts**: create SLOs (e.g., p95 latency & error rate) and alert via SNS/PagerDuty; annotate charts with deploys/model version swaps. (Grafana/AMG [**dashboards**](https://docs.aws.amazon.com/grafana/latest/userguide/dashboard-overview.html).) ([AWS Documentation](https://docs.aws.amazon.com/grafana/latest/userguide/dashboard-overview.html))
- **Analyze long-term trends** in a time-series store (e.g., MongoDB TS) to compare pre/post-deploy metrics and capacity needs. ([**MongoDB Time Series**](https://www.mongodb.com/docs/manual/core/timeseries-collections/).) ([MongoDB](https://www.mongodb.com/docs/manual/core/timeseries-collections/))

### Minimal code example: publish inference latency to CloudWatch

Use this on the server side where inference runs.

`import time, boto3` `cloudwatch = boto3.client('cloudwatch')` `start = time.time()` `# ... run model inference ...` `elapsed_ms = (time.time() - start) * 1000` `cloudwatch.put_metric_data(` `Namespace='CVPipeline',` `MetricData=[{` `'MetricName': 'InferenceLatency',` `'Dimensions': [` `{'Name': 'ModelName', 'Value': 'ResNet50-v2'},` `{'Name': 'Stage', 'Value': 'Inference'}` `],` `'Value': elapsed_ms,` `'Unit': 'Milliseconds'` `}]` `)`

(Referenced API: [**PutMetricData**](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/cloudwatch/client/put_metric_data.html).) ([Boto3](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/cloudwatch/client/put_metric_data.html))
