Introduction

This section describes the FunctionGraph namespaces, function metrics, and dimensions reported to Cloud Eye. You can view function metrics and alarms by using the Cloud Eye console or calling APIs.

Namespaces

Constraints

The metrics displayed on the console vary depending on the region. All metrics supported by FunctionGraph are listed here.

Function Metrics

Table 1 Function metrics

Metric ID	Metric Name	Description	Value Range	Unit	Conversion Rule	Monitored Object (Dimension)	Monitoring Period of Raw Data (Minute)
count	Invocations	Number of function invocations.	≥ 0	Count	None	Function	5
failcount	Errors	Number of invocation errors. The following errors are included: Function request error (causing an execution failure and returning status code 200) Function syntax or execution error	≥ 0	Count	None	Function	5
rejectcount	Throttles	Number of function throttles. It indicates the number of times that FunctionGraph throttles your functions due to the resource limit.	≥ 0	Count	None	Function	5
concurrency	Concurrency	The number of requests that can be processed concurrently.	≥ 0	Count	None	Function	5
reservedinstancenum	Reserved Instances	Number of instances reserved for running a function.	≥ 0	Count	None	Function	5
