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 AWS AK that meets the requirements in advance (For simplicity's sake, you can directly grant the global read-only permission for CloudWatch CloudWatchReadOnlyAccess)

To synchronize the monitoring data of AWS ELB cloud resources, we install the corresponding collection script: Guance Integration（AWS-LambdaCollect）

Click [ Install ] and enter the corresponding parameters: AWS AK, AWS 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¶

1. 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
2. On the Guance platform, click [ Infrastructure / Custom ] to check whether asset information exists
3. On the Guance platform, press [ Metrics ] to check whether monitoring data exists

Metric¶

Configure AWS Cloud - cloud monitoring. The default metric set is as follows. You can collect more metrics by configuring them.
