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.
Legal disclaimer
The network latency data and other performance data provided by the network performance observation feature are for your reference only. Alibaba Cloud does not provide any commitment or guarantee for the accuracy and timeliness of the data. The actual network performance data shall prevail.
The network latency data displayed by the network performance observation feature is collected by probing clusters of Alibaba Cloud. The probing clusters periodically send and receive probe packets and report the aggregated data. The network performance data is displayed on the Cloud Network Performance and Internet Connection Quality pages in the NIS console. The test machines deployed in the probing clusters are isolated from your resources. They do not affect or consume your resources. The data displayed 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 value below which 10% of the data values fall in an ascending sorted dataset
P50: the median value of an ascending sorted dataset
P90: the value above which 10% of the data values fall in an ascending sorted dataset
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.
Each cell in the grid shows the average latency that an ECS instance in a zone on the x-axis takes to connect to an 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.
