After you deploy an application on Serverless App Engine (SAE), SAE automatically collects CPU, load, memory, network, and disk metrics from the underlying instance and displays them as dynamic charts. All monitoring data is aggregated at the application level.
Before you begin
Monitoring data is available approximately 2 minutes after collection. Real-time dashboards are not supported.
If an application is upgraded or scaled, its instances change and monitoring data is interrupted and becomes discontinuous.
By default, the Basic Monitoring page displays grouped data from the previous hour.
For applications created before May 11, 2021, restart the application before viewing the new metrics.
Prometheus dashboards are supported.
View monitoring data
Log on to the SAE console. In the left-side navigation pane, choose Applications > Applications.
In the top navigation bar, select a region. From the Namespace drop-down list, select a namespace, then click the target application name.
On the Basic Information page, click Basic Monitoring in the left-side navigation pane.
On the Basic Monitoring page, select a resource type from the Resource type drop-down list:
Application (default): displays the average metric values calculated across all instances.
Instance: displays metric values for each individual instance.
Move the pointer over a data point on the chart's x-axis to view the metric value at that point in time.
Available metrics
SAE provides the following metrics on the Basic Monitoring page:
| Metric | Description |
|---|---|
| CPU utilization | Percentage of CPU capacity used by the instance |
| Average system load | Average number of processes waiting for CPU time |
| Memory usage | Amount of memory consumed by the instance |
| Network inbound and outbound rate | Rate of inbound and outbound network traffic for the instance |
| Network packets | Number of inbound and outbound network packets |
| Disk usage | Disk space used by the instance |
| Disk IOPS | Number of read and write operations per second on disk |
| Disk throughput | Rate of data read from and written to disk |
| TCP connections | Number of active TCP connections on the instance |
