HUAWEI CLOUD FunctionGraph¶

HUAWEI CLOUD FunctionGraph display metrics include count,failcount,rejectcount,concurrency,reservedinstancenum and so on, these metrics Indicates the operation of function for FuntionGraph.

Config¶

Install Func¶

Recommend opening 「Integrations - Extension - DataFlux Func (Automata)」: All preconditions are installed automatically, Please continue with the script installation

If you deploy Func yourself,Refer to Self-Deployment of Func

Installation script¶

Tip：Please prepare HUAWEI CLOUD AK that meets the requirements in advance（For simplicity's sake, You can directly grant the global read-only permission for CloudWatch ReadOnlyAccess）

To synchronize the monitoring data of HUAWEI CLOUD FunctionGraph cloud resources, we install the corresponding collection script：「Guance Integration（HUAWEI CLOUD-FunctionGraphCollect）」(ID：guance_huaweicloud_functiongraph)

Click 【Install】 and enter the corresponding parameters: HUAWEI CLOUD AK, HUAWEI CLOUD account name.

tap【Deploy startup Script】,The system automatically creates Startup script sets,And automatically configure the corresponding startup script.

Then, in the collection script, add the collector-Configs and cloudwatch-Change the regions in configs to the actual regions

After this function is enabled, you can view the automatic triggering configuration in「Management / Crontab Config」.Click【Run】,you can immediately execute once, without waiting for a regular time.After a while, you can view task execution records and corresponding logs.

We collected some configurations by default, as described in the Metrics column Configure custom cloud object metrics

Verify¶

In「Management / Crontab Config」check whether the automatic triggering configuration exists for the corresponding task,In addition, you can view task records and logs to check whether exceptions exist
On the observation cloud platform, click 「Infrastructure / Custom」 to check whether asset information exists
On the observation cloud platform, press 「Metrics」 to check whether monitoring data exists

Metric¶

Configure HUAWEI SYS.FunctionGraph. The default metric set is as follows. You can collect more metrics by configuring them HUAWEI CLOUD CloudWatch Metrics Details

Metric ID	Metric Name	Description	Value Range	Monitored Object	Monitoring Period of Raw Data (Minute)
`count`	Invocations	Number of function invocations Unit: Count	≥ 0 counts	Functions	1
`failcount`	Errors	Number of invocation errors. The following errors are included:Function request error (causing an execution failure and returning error code 200). Function syntax or execution error. Unit: Count	≥ 0 counts	Functions	1
`rejectcount`	Throttles	Number of function throttles. That is, the number of times that FunctionGraph throttles your functions due to the resource limit. Unit: Count	≥ 0 counts	Functions	1
`concurrency`	Number of concurrent requests	Maximum number of concurrent requests during function invocation. Unit: Count	≥ 0 counts	Functions	1
`reservedinstancenum`	Number of reserved instances	Number of reserved instances. Unit: Count	≥ 0 counts	Functions	1
`duration`	Average duration	Average duration of function invocation. Unit: ms	≥ 0 ms	Functions	1
`maxDuration`	Maximum duration	Maximum duration of function invocation. Unit: ms	≥ 0 ms	Functions	1
`minDuration`	Minimum duration	Minimum duration	≥ 0 ms	Functions	1

Object¶

The collected HUAWEI CLOUD SYS.FunctionGraph object data structure can be seen from the [ Infrastructure - Custom] object data.

  }
}

Note: The fields in 'tags' and' fields' may change with subsequent updates

Tip 1: tags.name value as instance ID, it is th uniquely identify.

Tip 2: fields.last_modified、fields.message、fields.strategy_configare all the JSON serialized strings.
