How Do I Check Whether the Bandwidth Exceeds the Limit?

Symptom

The bandwidth size configured when buying a dedicated or shared bandwidth is the upper limit of the outbound bandwidth. If the web applications that depend on the Internet freeze, check whether the dedicated bandwidth of the EIP bound to the ECS is greater than the configured bandwidth size.

If the bandwidth exceeds the configured bandwidth size, packet loss may occur. To ensure normal service running, it is recommended that you monitor the bandwidth.

Method 1

Query the historical dedicated bandwidth usage of an EIP.

  1. Log in to the management console and view the EIP bound to the ECS.

  2. On the Cloud Eye console, click Event Monitoring.
    Figure 2 Event Monitoring
  3. Click View Event.

    If the event EIP bandwidth overflow is not displayed, the dedicated bandwidth of the EIP does not exceed the limit.

    If the event EIP bandwidth overflow is displayed, the dedicated bandwidth of the EIP has exceeded the limit. To ensure stable service running, increase the bandwidth. For details, see Modifying EIP Bandwidth.

  • EIP bandwidth overflow is only launched in regions CN North-Beijing1, CN East-Shanghai2, and CN South-Guangzhou regions.
  • Cloud Eye does not display the shared bandwidth details on the Event Monitoring page. For details, see Cloud Eye User Guide.

Method 2

Create an alarm rule to generate alarms when the bandwidth exceeds the limit.

  1. Log in to the management console, under Management & Deployment, click Cloud Eye. On the Cloud Eye console, choose Alarm Management > Alarm Rules.

  2. Click Create Alarm Rule and configure an alarm rule to generate alarms when the bandwidth exceeds the limit.
    Figure 5 Create Alarm Rule

When the actual bandwidth exceeds the limit, an alarm is generated and the system automatically sends a notification.

The basic alarm function is free of charge. Simple Message Notification (SMN) sends you alarm notifications, and this service will be billed. For details, see Cloud Eye User Guide.
