You can use the scaling group monitoring feature to view metrics such as the CPU utilization, memory usage, loads, system disk read/write, and network bandwidth of all Elastic Compute Service (ECS) instances in your scaling group. This allows you to obtain the utilization of resources in the scaling group within a month.
- This topic is only suitable for the scaling groups that contain ECS instances.
- You can view the following types of metrics:
- CPU, Memory, and Load Metrics: CPU Utilization (%), Memory Usage (%), and Loads.
- System Disk Metrics: System Disk Read/Write BPS (byte/s) and System Disk IOPS (count/s)
- Network Metrics: Public Bandwidth (bit/s) and Internal Bandwidth (bit/s).
- Log on to the Auto Scaling console.
- In the left-side navigation pane, click Scaling Groups.
- In the top navigation bar, select a region.
- Find a scaling group and go to the details page of the scaling group. You can use
one of the following methods to go to the details page:
- Click the ID of the scaling group in the Scaling Group Name/ID column.
- Click Details in the Actions column of the scaling group.
- In the upper part of the page that appears, click the Scaling Group Monitoring tab.
- View the changes in the metrics of instances in the scaling group.
In the following figure, CPU, Memory, and Load Metrics is used as an example.
- You can click a monitoring dimension such as Average or Maximum in the upper part of the monitoring chart to hide or show relevant data in the chart.
- You can click the icon in the chart to zoom in the monitoring chart. You can also select a time range in the enlarged monitoring chart to view data of a specific time period.
- If a monitoring chart has no data, no event-triggered tasks that correspond to the metric are created. Create an event-triggered task as prompted. For more information, see Create an event-triggered task.
- The chart varies based on the metric that you select when you create an event-triggered
task. For example, if you set Monitoring Metric to System Disk Read (Byte/s) or System Disk Write (Byte/s), you can view the chart of the System Disk Read/Write BPS (byte/s) metric in the System Disk Metrics section.
Note The metrics that are available for the Monitoring Metric parameter in the Auto Scaling console shall prevail.
