• Function-level metrics

  FunctionGraph differentiates the metrics of a function by version, allowing you to query the metrics of a specific function version.

  View the metrics on the Monitoring tab page of a function. The metrics include invocation count, execution duration (including the maximum, average, and minimum durations), invocation errors, and throttled invocations, as shown in Figure 2. For details, see Viewing Function Metrics.

  • Creating an alarm rule

  Create an alarm rule for a function to report metrics to Cloud Eye for better monitoring.

  On the Monitoring tab page of the function details page, click Create Alarm Rule. Select a metric and set an alarm policy. After the alarm rule is created, click View details in the displayed message to view details of the alarm rule on the Cloud Eye console. On the Alarm Rules page, click View Graph in the Operation column of the alarm rule to view function metrics. Figure 3 shows the function monitoring graph.
