The network performance observation feature of Network Intelligence Service (NIS) allows you to view average network latencies between zones in the same Alibaba Cloud region or between Alibaba Cloud regions. This way, you can select a suitable region or zone to deploy your services based on the latency data. The feature also allows you to view the latencies of inter-region connections between Enterprise Edition transit routers. This way, you can select a suitable connection based on your business requirements.
Statements
The network latency data and other performance data provided by the network performance observation feature are for your reference only. Alibaba Cloud provides no commitment or guarantee for the accuracy and timeliness of the data. The actual network performance shall prevail.
The network latency data provided by the network performance observation feature is delivered by detection clusters built by Alibaba Cloud. The staging machines deployed in detection clusters regularly send and receive probe packets. Then, the statistical data is sent and displayed on the Cloud Network Performance and Internet Connection Quality pages in the NIS console. The staging machines deployed in detection clusters are isolated from your resources. Therefore, they do not affect or consume your resources. The data provided by the network performance observation feature is irrelevant to the resources that you deploy on Alibaba Cloud.

Performance metrics
Network performance within a region: You can view network latencies between Elastic Compute Service (ECS) instances deployed in the same region.
You can view average latencies between ECS instances in the same zone or different zones of the same region.
Alibaba Cloud detection clusters cannot cover some zones. Therefore, the data about the network latencies in these zones may be unavailable. The actual network latencies shall prevail.
Network performance between regions: You can view average latencies between network instances deployed in different regions.
You can view average latencies between ECS instances in different regions.
The following section describes specific statistical metrics on the reference latencies of platinum or gold inter-region connections between Enterprise Edition transit routers.
P10: the top 10% of values after the data is sorted in ascending order
P50: the median
P90: the last 10% of values after the data is sorted in ascending order
View network performance within a region
Log on to the NIS console.
In the left-side navigation pane, choose .
On the Intra-Region tab, click Compute Instance Connection.
Select the region where you want to view network latencies from the drop-down list.
Turn on Display Latency to view specific latency data.
You can view the following information from the grid in the Average Latency among Zones section:
The x-axis and y-axis display the zones of the region that you selected.
A cell in the grid shows the average latency that an ECS instance in a zone on the x-axis takes to connect to the ECS instance in a zone on the y-axis. If the zones on the x-axis and the y-axis are the same, the cell shows the average latency that an ECS instance takes to connect to another ECS instance deployed in the same zone of the region that you selected.
Alibaba Cloud detection clusters cannot cover some zones. Therefore, the data about the network latencies in these zones may be unavailable. The actual network latencies shall prevail.
You can click a cell in the grid of the Average Latency among Zones section to view the latencies of 1 hour before the current time in the line chart that appears.
View network performance between regions
Log on to the NIS console.
In the left-side navigation pane, choose .
On the Cloud Network Performance page, click the Inter-Region tab and view latency data.
View average latencies between ECS instances in different regions
Click the Table or Map tab and select regions. Then, view the round-trip latencies between instances in the selected regions.
NoteBy default, the real-time average latencies among the US (Virginia), US (Silicon Valley), and China (Hong Kong) regions are displayed on the Map tab.
Move the pointer over a link on the map. In the message that appears, click Learn More to view the latencies of 1 hour before the current time in the line chart that appears.
View the reference latencies of inter-region connections between transit routers deployed on a Cloud Enterprise Network (CEN) instance
Click the Instance tab, specify the parameters described in the following table, and then click View Inter-region Latency.
Parameter
Description
CEN instance ID
Select the ID of the CEN instance to which the desired TR belongs.
Region
Select a desired region.
Instance ID of the inter-region connection
Select the instance ID of the inter-region connection.
Time range
Select the time range of the latency data that you want to view. You can also specify a custom time range.
You can retrieve data within the last seven days.
NoteBy default, the average latency data of the P50 metric for the platinum or gold inter-region connections is displayed. You can view the data of the P10 and P90 metrics based on your business requirements.
