Network Intelligence Service:Monitor cloud network performance

Supported regions

Cloud network intercommunication performance metrics

• Network performance within a region: The network latency for access between ECS instances in the same region.

  • The average latency for access between ECS instances in different zones of the same region.

  • The Alibaba Cloud probing clusters do not cover all zones, so data for some zones may be unavailable. The data displayed in the console is the authoritative source.

• Network performance between regions: The latency for access between network instances in different regions.

  • The average latency for access between ECS instances in different regions.

  • The reference latency for Platinum or Gold links of an inter-region connection of an Enterprise Edition TR. The statistical metrics are as follows:

    • P10: The value at the 10th percentile of a dataset sorted in ascending order.

    • P50: The value at the 50th percentile of a dataset sorted in ascending order, which is the median.

    • P90: The value at the 90th percentile of a dataset sorted in ascending order.

View network performance within a region

1. Log on to the NIS console.

2. In the navigation pane on the left, choose Performance Monitoring > Cloud Network Performance.

3. On the Intra-region Network Performance tab, click Compute Instance Connection.

4. Select the region for which you want to view the latency.

5. Turn on the Display Latency switch to view the latency data.

   The following describes the Average Latency Between Zones heatmap:

   • The x-axis and y-axis represent the zones of the selected region.

   • Each colored block represents the average latency of a connection from an ECS instance in a zone on the x-axis to an ECS instance in a zone on the y-axis. If a block corresponds to the same zone on both axes, it represents the average latency between ECS instances within that zone.

   • The Alibaba Cloud probing clusters do not cover all zones, so data for some zones may be unavailable. The data displayed in the console is the authoritative source.

6. Click a colored block in the Average Latency Between Zones heatmap. A line chart appears that shows the latency history for the previous hour.

View network performance between regions

1. Log on to the NIS console.

2. In the navigation pane on the left, choose Performance Monitoring > Cloud Network Performance.

3. On the Cloud Network Performance page, click the Inter-region Network Performance tab to view the following latency data.

   • View the average cross-region access latency between ECS instances

     1. Click the Table View or Map View tab. Then, select regions to view the bidirectional latency between instances in the destination regions.

        

        

        Note

        By default, the Map View tab displays the real-time average latency of the links between each pair of the following three regions: US (Virginia), US (Silicon Valley), and China (Hong Kong).

     2. On the Map View tab, click View Details on any link. A line chart appears that shows the latency history for the previous hour.

   • View the reference latency of the physical link for a CEN inter-region connection

     Click the Instance View tab. Then, configure the following parameters and click View Inter-region Latency.

     Parameter	Description
     CEN instance ID	Select the ID of the CEN instance to which the destination TR belongs.
     Region	Select the destination region of the inter-region connection.
     Inter-region connection instance ID	Select the instance ID of the inter-region connection.
     Time	Select the time range for which you want to view the reference latency data. You can also specify a custom time range. You can query data from the last 7 days. The earliest start time that you can select is 7 days ago.

     Note

     By default, the average latency data for the P50 metric of Gold and Platinum links is displayed. You can view the data for the P10 and P90 metrics as needed.
