When bandwidth usage spikes or packets are dropped, catching the issue early prevents service degradation. CloudMonitor (CMS) collects real-time metrics for your Internet Shared Bandwidth instance and plots them as time-series charts. You can also configure threshold-triggered alerts so that CloudMonitor notifies you automatically when a metric crosses your defined threshold.
View monitoring data
CloudMonitor samples metrics at regular intervals and retains historical data for up to one month. You can view data for the last 1 hour, 3 hours, 6 hours, 12 hours, or a custom time range within that period.
There are two ways to access the monitoring charts.
From the Internet Shared Bandwidth console
Log on to the Internet Shared Bandwidth console. In the top menu bar, select the region where your instance is located.
Open the monitoring charts for the target instance using either of the following methods:
Click the
icon in the Monitor column.Click the instance ID. On the Basic Information tab, scroll to the Monitor area.
From the CloudMonitor console
Log on to the CloudMonitor console. In the left navigation pane, click Cloud Service Monitoring.
Click Share Bandwidth Packages. Select the region where the instance is located, then click Monitoring Charts in the Actions column of the target instance.
Monitoring metrics
Internet Shared Bandwidth exposes eight metrics in CloudMonitor. The bandwidth usage metrics (percentage values) are the most actionable for capacity planning and alert configuration.
Metric | Description |
Inbound Bandwidth | Bandwidth consumed by inbound traffic from external sources to the instance |
Outbound Bandwidth | Bandwidth consumed by outbound traffic from the instance to external destinations |
Inbound Packet Rate | Number of packets received by the instance per second |
Outbound Packet Rate | Number of packets sent by the instance per second |
Outbound Bandwidth Usage(Value) | Outbound bandwidth consumption as a percentage of the total instance bandwidth |
Inbound Bandwidth Usage(Value) | Inbound bandwidth consumption as a percentage of the total instance bandwidth |
Rate of Outbound Packets Dropped | Rate at which outbound packets are dropped due to outbound rate limiting |
Rate of Inbound Packets Dropped | Rate at which inbound packets are dropped due to inbound rate limiting |
Create a threshold-triggered alert rule
A threshold-triggered alert rule monitors your instance continuously. When a metric crosses the threshold you define, CloudMonitor sends an alert notification—so you can act on anomalies without watching the charts.
If you release an Internet Shared Bandwidth instance, CloudMonitor deletes all threshold-triggered alert rules associated with that instance.
Steps:
Log on to the CloudMonitor console.
In the left navigation pane, choose Alerts > Alert Rules. Click Create Alert Rule and set Product to Share Bandwidth Packages. For configuration details, see Create an alert rule.
