HTTP Traffic Analysis

The HTTP Traffic tab provides detailed insights into your application's web traffic patterns and performance metrics. Analyze request volume, bandwidth consumption, cache effectiveness, and security events.

Getting Started​

Access HTTP Traffic Monitoring​

  1. Navigate to Monitoring from the main sidebar
  2. Click the HTTP Traffic tab
  3. You'll see the configuration panel and metric cards

Configuration​

Before viewing traffic data, you need to configure your Cloudflare Zone ID:

Setting Up Your Cloudflare Zone ID​

  1. In the Configuration card, enter your Cloudflare Zone ID

    • Find your Zone ID in your Cloudflare dashboard: Domain → Overview → API
    • Format: A 32-character hexadecimal string (e.g., b032a57f01eac20ad3c4e8ba2a05bb19)

  2. Select your desired Date Range

    • Default: Last 30 days
    • Use the date picker for custom analysis periods
    • Adjust to compare specific time periods

  3. Click Fetch Data to retrieve traffic analytics

    • First-time fetch may take a few seconds
    • Data updates based on your selected date range
    • System will display "Fetching..." while loading
note

You need valid Cloudflare API credentials and appropriate permissions to fetch traffic data. Demo mode displays sample data for testing purposes.

Key Metrics​

The HTTP Traffic tab displays three primary metric cards:

Total Requests​

Shows: Complete count of HTTP requests in your date range

Why It Matters: Indicates traffic volume and application popularity

Interpretation:

  • Compare across time periods to identify growth
  • Look for anomalies indicating unusual activity
  • Use as baseline for performance testing

Example: 1.2M requests over 30 days = 40K requests/day average

Cache Hit Rate​

Shows: Percentage of requests served from cache (%)

Why It Matters:

  • Higher cache hit rates reduce server load
  • Improve user experience with faster responses
  • Reduce bandwidth costs

Optimal Range: 80-95% is considered excellent

Total Bytes: Displayed below percentage shows total bandwidth transferred

Optimization Tips:

  • Increase TTL for static content
  • Review cache rules in Cloudflare
  • Check for incorrectly cached dynamic content

Security Threats​

Shows: Number of requests blocked by security rules

Why It Matters: Indicates attack attempts and malicious traffic

What To Do:

  • Monitor threat trends over time
  • Review and adjust security rules if legitimate traffic is blocked
  • Consider enabling stricter WAF rules
  • Rate limit suspicious sources

Alert Triggers:

  • Sudden spike in threats
  • Threats from specific countries
  • Pattern-based attack detection

Traffic Charts​

Traffic Over Time​

An area chart showing dual metrics:

  • Blue Area: HTTP request volume over time
  • Green Area: Unique visitor count over time

Uses:

  • Identify traffic spikes and patterns
  • Correlate with business events
  • Detect seasonal trends
  • Spot anomalies

How to Read:

  • X-axis: Time progression
  • Y-axis: Request/visitor count
  • Peaks: High traffic periods
  • Valleys: Low traffic periods

Cache Distribution (Pie Chart)​

Shows the proportion of cached vs. un-cached requests:

  • Cached Requests: Served from edge servers (faster, lower cost)
  • Un-cached Requests: Processed by origin server (more resource-intensive)

Target Distribution:

  • 80-95% cached (excellent)
  • 50-80% cached (good)
  • Below 50% cached (needs optimization)

Optimization Strategy:

  1. Identify content with low cache rates
  2. Increase TTL for static content
  3. Review cache bypass rules
  4. Remove unnecessary cache exceptions

Top Countries (Bar Chart)​

Horizontal bar chart displaying top traffic sources by geographic location:

Information Provided:

  • Rank by request volume
  • Geographic distribution
  • Regional traffic patterns

Uses:

  • Content localization decisions
  • CDN optimization
  • Market analysis
  • Regional deployment strategies

Actions:

  • Deploy edge servers in high-traffic regions
  • Localize content for top countries
  • Adjust server resources based on geography

Daily Statistics Table​

A detailed daily breakdown showing comprehensive metrics:

Reading the Table​

Example Row Analysis:

  • Date: 2026-01-06
  • Requests: 50,000
  • Cached: 42,000
  • Cache Rate: 84% (good)
  • Bandwidth: 2.5GB
  • Visitors: 5,000
  • Threats: 123

Interpretation: Good cache performance, significant traffic, moderate threat activity

Using Daily Data​

  • Identify trends: Look for consistent patterns
  • Spot anomalies: Compare to previous days
  • Plan capacity: Review peak days
  • Track growth: Compare across weeks/months

Export & Reporting​

Exporting HTTP Traffic Data​

  1. Click the Export button in the HTTP Traffic tab
  2. A CSV file downloads with filename: http-traffic-YYYY-MM-DD.csv
  3. CSV includes all columns from the Daily Statistics table

CSV File Format​

The exported CSV contains these columns:

Date, Requests, Cached, Un-cached, Total Bytes, Unique Visitors, Threats

Export Use Cases​

  • Analysis: Import into spreadsheet applications
  • Reporting: Create custom reports
  • Archival: Long-term data storage
  • Sharing: Distribute to stakeholders
  • Compliance: Regulatory requirements

Common Monitoring Scenarios​

Scenario 1: Investigate Traffic Spike​

Situation: Notice unusual traffic increase

Steps:

  1. Go to HTTP Traffic tab
  2. Adjust date range to include the spike period
  3. Review Traffic Over Time chart to identify peak times
  4. Check Top Countries to see if spike is geographic
  5. Review Daily Statistics table for the affected day

Questions to Answer:

  • What time did the spike occur?
  • Where is the traffic coming from?
  • Is it legitimate traffic or attack?
  • Did cache hit rate change?

Scenario 2: Optimize Cache Performance​

Situation: Cache hit rate below 80%

Steps:

  1. Check Cache Distribution pie chart
  2. Review cache rate in Daily Statistics
  3. Identify which content has low cache rates
  4. Check Cloudflare cache rules

Steps:

  1. Go to HTTP Traffic tab
  2. Monitor the Security Threats metric daily
  3. If threats spike:
    • Review which countries/IPs are attacking
    • Check attack pattern in Traffic Over Time chart
    • Analyze detailed logs

Response Actions:

  • Enable stricter security rules in Cloudflare
  • Rate limit suspicious sources
  • Update WAF (Web Application Firewall) rules
