#OpenTelemetry Traffic Metrics

The platform offers a wealth of traffic metrics data, allowing users to analyze the quality of service traffic from multiple dimensions.

#Service Traffic Monitoring

#Viewing Service Traffic Quality

Prerequisites

The service has been injected with a Java Agent, please refer to Adding Services for implementation.

Steps

1. In the left navigation bar, click Monitoring.

2. Select the service and time range for which you want to view monitoring data.

   Note: The query time range is limited by the retention period of Prometheus monitoring data. For example, if monitoring data is retained for up to 7 days and the set time range is for the last 30 days, the statistical data will cover only 7 days.

3. Click the respective tabs to view the service's traffic monitoring data and JVM monitoring data.

#Regular Operations

• Refresh Data: The monitoring statistics on the current page are automatically refreshed only once when the page is opened. To refresh again, you can use the following two methods:

  • Manual Refresh: Click the in the bottom right corner of the page to manually refresh the data.

  • Set Auto Refresh (default is off): Click the to set the interval for auto-refreshing the data.

• View/Set Legend: Click the in the top right corner of the chart to expand the legend in the monitoring chart. Click on the legend to hide/show the corresponding curve in the chart.

• View Monitoring Chart in Large: Click the in the top right corner of the chart to view an enlarged, more detailed monitoring chart in the pop-up dialog.

#Monitoring Data Explanation

Monitoring Metrics	Description
Average Response Time	Average response time within the query time range (total response time/total number of responses).
Average Incoming/Outgoing RPS	Average value of incoming/outgoing RPS (Requests Per Second) during the query time range.
Response Time	Response time between services or within a service itself, displayed as average, TP 50, TP 95, TP 99. TP (Top Percentile) xx indicates the minimum duration required for xx percent of network requests, commonly used in system performance monitoring scenarios. Hover over the curve to view the response time for a particular period.
Incoming/Outgoing RPS	Total incoming/outgoing traffic RPS and error incoming/outgoing traffic RPS within the query time range. RPS = Number of requests during the query time / Query duration (s).
Incoming/Outgoing Traffic	Total incoming/outgoing request volume within the query time range, and traffic proportion by HTTP return codes (normal/2xx, 3xx, 4xx, 5xx). Hover over the bar chart to view the traffic proportion for each category.
Client Traffic Comparison	Client refers to the client service (downstream service) that makes requests to the current service (upstream service). Client Traffic Comparison will compare and display the Response Time, Incoming RPS, and incoming RPS Error Rate (Error RPS/RPS) of different clients calling the current service. Explanation: - unknown client refers to the collection of clients (HTTP protocol) within the service mesh that call the current service and whose traffic is not managed by OpenTelemetry. - If the client belongs to the current namespace, clicking the Trace next to the client name will redirect to the trace page.
