Huawei Cloud FunctionGraph¶

The displayed metrics for Huawei Cloud FunctionGraph include the number of calls, number of errors, number of rejections, concurrency count, reserved instance count, and run time (including maximum run time, minimum run time, and average run time), which reflect the operational status of the FunctionGraph function.

Configuration¶

Install Func¶

It is recommended to activate the Guance integration - extension - DataFlux Func (Automata): all prerequisites will be automatically installed. Please continue with the script installation.

If you deploy Func on your own, refer to Self-deployed Func

Installation Script¶

Note: Please prepare a Huawei Cloud AK that meets the requirements in advance (for simplicity, you can directly grant global read-only permission ReadOnlyAccess)

To synchronize the monitoring data of HUAWEI FunctionGraph, we install the corresponding collection script: 「Guance Integration (Huawei Cloud-FunctionGraph Collection)」(ID: guance_huaweicloud_functiongraph)

After clicking 【Install】, input the corresponding parameters: Huawei Cloud AK, Huawei Cloud account name.

Click 【Deploy Startup Script】, and the system will automatically create a Startup script set and automatically configure the corresponding startup script.

After enabling, you can see the corresponding automatic trigger configuration in 「Manage / Automatic Trigger Configuration」. Click 【Execute】to immediately execute once without waiting for the scheduled time. After a short wait, you can view the execution task records and corresponding logs.

We default collect some configurations, details see the metric section

Configure custom cloud object metrics

Verification¶

In 「Manage / Automatic Trigger Configuration」, confirm whether the corresponding task has the corresponding automatic trigger configuration, and at the same time, you can check the corresponding task records and logs to check for any abnormalities.
On the Guance platform, under 「Infrastructure / Custom」, check if there is asset information.
On the Guance platform, under 「Metrics」, check if there are corresponding monitoring data.

Metrics¶

After configuring HUAWEI SYS.FunctionGraph, the default metric sets are as follows. You can collect more metrics through configuration. Huawei Cloud Monitoring Metric Details

Metric ID	Metric Name	Metric Meaning	Value Range	Measurement Object	Monitoring Cycle (Raw Metric)
`count`	Number of Calls	This metric counts the number of function calls. Unit: times	≥ 0 counts	Function	1 minute
`failcount`	Error Count	This metric counts the number of function call errors. The following two situations will both be counted as errors: abnormal function requests that prevent execution from completing and return 200. Syntax errors or execution errors in the function itself. Unit: times	≥ 0 counts	Function	1 minute
`rejectcount`	Rejected Count	This metric counts the number of rejected function calls. Rejected count refers to the number of requests rejected due to too many concurrent requests and system flow control. Unit: times	≥ 0 counts	Function	1 minute
`concurrency`	Concurrency	This metric counts the maximum number of concurrent requests processed by simultaneous function calls. Unit: items	≥ 0 counts	Function	1 minute
`reservedinstancenum`	Reserved Instance Count	This metric counts the number of reserved instances configured for the function. Unit: items	≥ 0 counts	Function	1 minute
`duration`	Average Run Time	This metric counts the average run time of function calls. Unit: milliseconds	≥ 0 ms	Function	1 minute
`maxDuration`	Maximum Run Time	This metric counts the maximum run time of function calls. Unit: milliseconds	≥ 0 ms	Function	1 minute
`minDuration`	Minimum Run Time	This metric counts the minimum run time of function calls. Unit: milliseconds	≥ 0 ms	Function	1 minute

Objects¶

The collected HUAWEI SYS.FunctionGraph object data structure can be seen from 「Infrastructure - Custom」.
