FunctionGraph Metrics

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

SYS.FunctionGraph

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
failRate	Error Rate	Percentage of errors to the total invocations of a function.	0% ≤X≤ 100%	%	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
duration	Average Duration	Average duration of function invocation.	≥ 0 ms	ms	None	Function	5
maxDuration	Maximum Duration	Maximum duration of function invocation.	≥ 0 ms	ms	None	Function	5
minDuration	Minimum Duration	Minimum duration of function invocation.	≥ 0 ms	ms	None	Function	5
systemErrorCount	System Errors	Number of system errors that occur during function invocation.	≥ 0	Count	None	Function	5
functionErrorCount	Function Error Count	Number of function errors that occur during invocation.	≥ 0	Count	None	Function	5
payPerUseInstance	Elastic Instances	Number of instances used, excluding reserved ones.	≥ 0 counts	Count	None	Function	5
instances	Instances	Number of instances for function invocation.	≥ 0 counts	Count	None	Function	5
duration_p500	Duration (P50)	P50 execution duration of the function.	≥ 0 ms	ms	None	Function	5
duration_p800	Duration (P80)	P80 execution duration of the function.	≥ 0 ms	ms	None	Function	5
duration_p950	Duration (P95)	P95 execution duration of the function.	≥ 0 ms	ms	None	Function	5
duration_p990	Duration (P990)	P990 execution duration of the function.	≥ 0 ms	ms	None	Function	5
duration_p999	Duration (P999)	P999 execution duration of the function.	≥ 0 ms	ms	None	Function	5
memoryUsed	Memory	Memory used by the function.	≥ 0 MB	MB	None	Function	5
functionCost	Resource Usage	Resources used by the function (Memory x Duration).	≥ 0 MB	MB	None	Function	5
instanceUsage	Used Instances	Percentage of the used function instances to the total number.	0% ≤X≤ 100%	%	None	Function	5

errorCount	Number of errors	Total number of execution failures of workflow.	≥ 0	Count	None	Flow	1
running	Number of running	Number of running flows.	≥ 0	Count	None	Flow	1
rejectCount	Number of times to be restricted	Number of restricted flows.	≥ 0	Count	None	Flow	1
averageDuration	Run time	Average execution time of workflow.	≥ 0 ms	ms	None	Flow	1
notifyFailedCount	Number of notified errors	Total number of notified failures.	≥ 0	Count	None	Flow	1
ExecutionsStarted	Started Workflow Instances	Number of started workflow instances.	≥ 0	Count	None	Flow	1
