When multiple Elastic IP Addresses (EIPs) share a single Internet Shared Bandwidth instance, it can be difficult to identify which EIP is consuming the most bandwidth or causing abnormal traffic spikes. The Internet traffic analysis feature, provided by Network Intelligence Service (NIS), ranks all associated EIPs by data transfer volume so you can quickly pinpoint high-consumption EIPs and troubleshoot traffic anomalies.
Prerequisites
Before you begin, ensure that you have:
A purchased Internet Shared Bandwidth instance. See Create an Internet Shared Bandwidth instance
EIPs associated with the instance. See Add an EIP
View EIP traffic rankings
Log on to the Internet Shared Bandwidth console.
In the top navigation bar, select the region where the Internet Shared Bandwidth instance resides.
On the Internet Shared Bandwidth page, click the ID of the target instance.
On the Basic Information tab, click the EIP Traffic Ranking tab.
Click Use NIS Traffic Analyzer (Commercial Edition).
Refer to Traffic analysis and analyze the EIP data transfers.
The EIP Traffic Ranking feature displays real-time data only and does not support querying historical traffic rankings or historical traffic data. To view historical traffic ranking data and historical traffic data, subscribe to Network Intelligence Service (NIS) and enable Traffic Analyzer (Commercial Edition). After you configure a data recording period, you can view historical traffic analysis results.
FAQ
Q: How do I identify the ECS instance responsible for costs in my Internet Shared Bandwidth plan?
A: You can use the EIP Traffic Ranking feature in the Internet Shared Bandwidth console or the Internet traffic analysis feature in Network Intelligence Service (NIS) to view the data transfer usage of each EIP in your Internet Shared Bandwidth instance. By identifying the EIP with the highest traffic usage, you can determine which EIP is generating the most costs. You can then check the EIP-to-ECS binding relationship to locate the specific ECS instance ID.
