Network Traffic Monitoring Overview

Overview

The Network Traffic Monitoring API allows you to analyze and monitor traffic from Naver's cloud platform. It is achieved through HTTP-based GET/POST/PUT/DELETE method sales.

Request Header

The following is an example of creating 'x-ncp-apigw-signature-v2' in Java.For more information, please refer to the API Gateway document.

public String makeSignature() {
    String space = " ";                    // one space
    String newLine = "\n";                    // new line
    String method = "GET";                    // method
    String url = "/photos/puppy.jpg?query1=&query2";    // url (include query string)
    String timestamp = "{timestamp}";            // current timestamp (epoch)
    String accessKey = "{accessKey}"            // access key id (from portal or sub account)
    String secretKey = "{secretKey}";

    String message = new StringBuilder()
        .append(method)
        .append(space)
        .append(url)
        .append(newLine)
        .append(timestamp)
        .append(newLine)
        .append(accessKey)
        .toString();

    SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes("UTF-8"), "HmacSHA256");
    Mac mac = Mac.getInstance("HmacSHA256");
    mac.init(signingKey);

    byte[] rawHmac = mac.doFinal(message.getBytes("UTF-8"));
    String encodeBase64String = org.apache.commons.codec.binary.Base64.encodeBase64String(rawHmac);

  return encodeBase64String;
}

Basic information

Before using the Network Traffic Monitoring API, I'll give you some basic information.

Metric and Dimension

• Metric means a numerical value that the user wants to handle.
• Dimension is a property of specific data that means which server belongs to, where it is located, and what value it is.

Aggregation

• Traffic collects performance data at 1-minute intervals and, if necessary, collects more often or rarely than 1-minute.
• There may be a delay of about 4 minutes in near real time.

Interval

• Aggregation currently runs every minute, 15 minutes, 30 minutes, 1 hour, and 1 day. For example, the 5-minute tally is based on the values collected at 10:00 to 10:04:59, 10:05 to 10:09:59, ...
• The aggregated results produce AVG and MAX values every 1 minute, 15 minutes, 30 minutes, 1 hour, and 1 day.
