Day 12 – Logging & Monitoring with Google Cloud Operations Suite

Introduction

In cloud environments, visibility into application and infrastructure performance is critical. Without proper logging and monitoring, troubleshooting, performance optimization, and compliance become impossible. Google Cloud Operations Suite (formerly Stackdriver) provides a comprehensive suite of tools for logging, monitoring, tracing, and alerting in GCP.

At Curiosity Tech, we emphasize mastering these tools because engineers must proactively detect issues, optimize performance, and ensure reliability in production-grade applications. This guide provides an in-depth understanding of Cloud Logging, Cloud Monitoring, Cloud Trace, and Cloud Debugger, with practical examples and strategic insights.


What is Google Cloud Operations Suite?

Google Cloud Operations Suite is a fully integrated observability platform for GCP, combining:

  1. Cloud Logging: Centralized log management.

  2. Cloud Monitoring: Metrics collection, dashboards, and alerts.

  3. Cloud Trace: Distributed request latency analysis.

  4. Cloud Debugger: Real-time inspection of applications.

  5. Cloud Profiler: Performance profiling of production applications.

These tools enable engineers to monitor infrastructure, debug applications, and analyze performance trends efficiently.


Core Components Explained

Cloud Logging

Cloud Logging is the central log repository for GCP, aggregating logs from:

  • Compute Engine

  • GKE Clusters

  • Cloud Functions

  • App Engine

  • Cloud Load Balancers

Key Features:

  • Real-time log ingestion

  • Advanced queries using Logs Explorer

  • Export to BigQuery or Cloud Storage for long-term analytics

  • Log-based metrics for monitoring trends

Example Query: Errors in GKE Pods

resource.type=”k8s_container”

severity=”ERROR”

timestamp >= “2025-09-01T00:00:00Z”


Cloud Monitoring

Cloud Monitoring collects metrics and telemetry data from your GCP resources and custom applications.

Features:

  • Prebuilt dashboards for GCP services

  • Custom dashboards for application-specific metrics

  • Alerts and notifications via email, SMS, Slack, or PagerDuty

  • Uptime checks and SLO/SLA monitoring

Example: CPU Usage Alert

  1. Metric: compute.googleapis.com/instance/cpu/utilization

  2. Condition: CPU > 80% for 5 minutes

  3. Action: Send email to DevOps team

Table: Common Metrics to Monitor
 | Resource Type | Important Metrics |
 |——————|———————————————————|
 | Compute Engine | CPU, Memory, Disk I/O, Network Traffic |
 | GKE Clusters | Pod status, Node CPU/Memory, Container Restarts |
 | Cloud SQL | Connections, Query Latency, Disk Usage |
 | Cloud Functions | Execution Count, Error Rate, Latency |


Cloud Trace & Debugger

Cloud Trace provides latency insights for distributed applications. Engineers can see request paths, detect bottlenecks, and optimize performance.

Cloud Debugger allows live inspection of running applications without stopping them. Combined, these tools provide end-to-end observability.

Practical Example:

  • Trace a slow checkout request in an e-commerce app.

  • Identify latency caused by database queries.

  • Debug the specific service code in production using Cloud Debugger.


Advanced Practices for Observability

  1. Centralize Logs: Consolidate all logs in Cloud Logging, including custom application logs.

  2. Create Dashboards: Use Cloud Monitoring to create team-specific dashboards for real-time insights.

  3. Implement Alerts: Proactively detect performance degradation or failures.

  4. Use Log-Based Metrics: Convert frequent log patterns into metrics for monitoring and alerting.

  5. Integrate with CI/CD Pipelines: Monitor deployments and performance regressions automatically.

Curiosity Tech labs teach engineers to build observability pipelines combining Logging, Monitoring, and Trace to simulate enterprise-level applications.


Practical Scenario: Multi-Service Monitoring

Scenario: An online marketplace with multiple microservices deployed on GKE.

  1. Logging: All container logs collected in Cloud Logging.

  2. Monitoring: CPU, memory, and request latency dashboards.

  3. Tracing: Track requests from frontend to backend and database.

  4. Alerts: Notify DevOps if pod restarts exceed a threshold or API latency > 2 seconds.
