How to determine the traffic baseline?

To determine the traffic baseline, you need to analyze historical data and identify patterns of normal traffic behavior over a specific period. This helps establish a reference point for detecting anomalies or unexpected changes.

Steps to Determine Traffic Baseline:

1. Collect Historical Data: Gather traffic metrics (e.g., requests per second, bandwidth usage, user sessions) from logs, monitoring tools, or analytics platforms over weeks or months.
2. Identify Patterns: Look for recurring trends, such as peak hours, seasonal fluctuations, or weekday vs. weekend differences.
3. Calculate Averages and Percentiles: Compute the mean, median, and 95th percentile of traffic to account for outliers.
4. Account for Growth Trends: If traffic is increasing over time, factor in growth rates to avoid setting an outdated baseline.
5. Validate with Business Context: Align the baseline with known events (e.g., marketing campaigns, product launches) to ensure accuracy.

Example:

A website typically receives 10,000 requests per minute between 9 AM and 5 PM on weekdays, with peaks of 15,000 requests during lunch hours. The baseline would include these averages and peaks, excluding abnormal spikes like a flash sale.

For cloud-based monitoring, Tencent Cloud's Cloud Monitor can help collect and analyze traffic data, while Tencent Cloud CLS (Cloud Log Service) provides log analysis to identify patterns. Tencent Cloud Auto Scaling can dynamically adjust resources based on deviations from the baseline.
