Log Explorer

Logs support troubleshooting and auditing.

6. What is Log Explorer?

Log Explorer allows engineers to search, filter, and analyze logs.

Capabilities:

  • Search logs
  • Filter by severity
  • Time-based queries
  • Export logs
  • Save queries

Example:

Severity = ERROR

↓

Last 30 Minutes

It is commonly used during production incidents.

Distributed Tracing

7. What is Cloud Trace?

Cloud Trace measures request latency across distributed applications.

Example:

Client

↓

API Gateway

↓

Order Service

↓

Payment Service

↓

Database

Each request receives a trace.

Benefits:

  • Latency analysis
  • Bottleneck identification
  • Service dependency analysis

8. Why is distributed tracing important?

Microservices involve multiple service calls.

Without tracing:

API Failed

↓

Unknown Cause

With tracing:

API

↓

Order Service

↓

Payment Service

↓

Database

↓

Problem Identified

Tracing significantly reduces troubleshooting time.

Performance Optimization

9. What is Cloud Profiler?

Cloud Profiler continuously analyzes application performance.

It identifies:

  • CPU hotspots
  • Memory usage
  • Expensive functions
  • Thread activity

Architecture:

Cloud Profiler

↓

Performance Analysis

Developers use it to optimize applications.

10. What is Error Reporting?

Error Reporting automatically groups application exceptions.

Instead of:

50,000 Stack Traces

It groups identical errors into:

NullPointerException

↓

Occurrences

↓

50,000

Benefits:

  • Easier debugging
  • Faster prioritization
  • Reduced noise

Reliability Engineering

11. What are Uptime Checks?

Uptime Checks verify application availability.

Example:

Every 1 Minute

↓

HTTPS Request

↓

Healthy?

↓

Yes / No

Supports:

  • HTTP
  • HTTPS
  • TCP

Uptime checks provide external availability monitoring.

12. What are Alerting Policies?

Alerting Policies notify engineers when monitored conditions occur.

Example:

Latency > 2 Seconds

↓

Alert

↓

Email

PagerDuty

Slack

Alerts support:

  • Metric thresholds
  • Log conditions
  • Uptime failures
  • SLO violations

Enterprise Monitoring

13. What are common monitoring mistakes?

Common mistakes:

  • No dashboards
  • Missing uptime checks
  • Ignoring traces
  • Monitoring only infrastructure
  • Too many alerts
  • No log retention
  • Missing SLO monitoring
  • No profiling
  • No error grouping
  • Alert fatigue

These reduce operational effectiveness.
