Function Monitoring

FunctionGraph is interconnected with Cloud Eye, allowing you to view function metrics without the need for any configurations.

FunctionGraph collects function metrics and displays aggregated results. Switch to your target function version before viewing metrics.

Log in to the FunctionGraph console. In the navigation pane, choose Functions > Function List.
Click the function to be configured to go to the function details page.
Choose Monitoring > Metrics, select an interval (last day, last 3 days, or custom), and check the running status of the function.

The following metrics are displayed: invocations, errors, duration (maximum, average, and minimum durations), throttles, and instance statistics.

Table 1 describes the function metrics.

**Table 1** Function metrics
Metric	Unit	Description
Invocations	Count	Total number of invocation requests, including invocation errors and throttled invocations. In case of asynchronous invocation, the count starts only when a function is executed in response to a request.
Duration	ms	Maximum Duration: the maximum duration a function is executed within a period. Minimum Duration: the minimum duration a function is executed within a period. Average Duration: the average duration a function is executed within a period.
Errors	Count	Number of times that your functions failed with error code 200 being returned. Errors caused by function syntax or execution are also included.
Throttles	Count	Number of times that FunctionGraph throttles your functions due to the resource limit.
Instance Statistics	Count	Numbers of concurrent requests and reserved instances.
