Network Monitoring

In live video streaming, random packet loss occurs when the outbound bandwidth reaches the upper limit. Therefore, attention must be paid to this metric of Elastic IP and Bandwidth.

This section describes how to set alarm rules for the outbound bandwidth usage of Elastic IP and Bandwidth.

Procedure

  1. Log in to the Cloud Eye console.
  2. In the navigation pane, choose Cloud Service Monitoring.
  3. On the displayed page, click the VPC dashboard name.
  4. Locate the row that contains the target VPC and choose More > Create Alarm Rule in the Operation column.
  5. On the Create Alarm Rule page, set Method to Configure manually and configure alarm policies for the monitored instance.

    You are advised to configure alarm rules for the EIPs and bandwidths involved in the service. Set the threshold of Outbound Bandwidth Usage to Raw data ≥ 90% of the purchased bandwidth.

    Table 1 Alarm policy description

    Parameter

    Example Value

    Description

    Metric Name

    Alarm policy 1: Bandwidths > Outbound Bandwidth Usage

    Alarm policy 2: Bandwidths > Inbound Bandwidth Usage

    Metric for triggering alarms.

    Statistic

    Raw data

    Metric value type. Cloud Eye supports the following statistics for metrics: Raw data, Avg., Max., Min., Variance, and Sum.

    Consecutive Triggers

    3 times (consecutively)

    Number of consecutive times that an alarm is triggered.

    Operator

    >=

    Operator used to compare metric value and the threshold.

    Threshold

    Critical: 90%

    Alarm threshold and unit.

    Frequency

    Daily

    How often alarms are repeatedly notified when there is already an alarm.
  6. Configure alarm notification parameters. For details, see Creating an Alarm Rule and Notifications.
    Table 2 Alarm notification parameters

    Parameter

    Example Value

    Description

    Alarm Notifications

    Enabled

    Whether to send an alarm notification when an alarm is triggered.

    Notified By

    Topic subscriptions or Account contact

    Select a notification method and recipients. You can select notification policies, contact groups, or topic subscriptions. If you select Account contact, notifications will be sent to the mobile number and email address specified during registration.

    Notification Window

    00:00–23:59

    If you select Contact groups or Topic subscriptions for Notified By, you need to set the notification window. The system sends notifications only within the notification window.

    Trigger Condition

    Generated alarm and Cleared alarm

    This parameter is available when Notified By is set to Contact groups or Topic subscriptions. You can select Generated alarm, Cleared alarm, or both.

    Notification Template

    System template

    This parameter is only available if you set Notified By to Contact groups or Topic subscriptions. You can select an existing template or create one to send alarm notifications.
  7. Click Create.

    When the bandwidth is abnormal, Cloud Eye sends real-time alerts via the SMN service.
