AWS DynamoDB DAX¶

The displayed Metrics for AWS DynamoDB DAX include CPU usage of nodes or clusters, the number of bytes received or sent on all network interfaces, the number of packets, etc. These Metrics reflect the operational status of DynamoDB DAX.

Configuration¶

Install Func¶

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

If you deploy Func manually, refer to Manual Deployment of Func

Installation Script¶

Note: Please prepare an Amazon Cloud AK that meets the requirements in advance (for simplicity, you can directly grant the CloudWatch read-only permission CloudWatchReadOnlyAccess)

Script for Enabling Managed Version¶

1. Log in to the Guance console.
2. Click on the 【Integration】 menu and select 【Cloud Account Management】.
3. Click 【Add Cloud Account】, choose 【AWS】, and fill in the required information on the interface. If you have already configured cloud account information before, skip this step.
4. Click 【Test】, and after a successful test, click 【Save】. If the test fails, check whether the related configuration information is correct and retest.
5. In the 【Cloud Account Management】 list, you can see the added cloud accounts. Click the corresponding cloud account and go to the details page.
6. Click the 【Integration】 button on the cloud account details page. Under the Not Installed list, find AWS DynamoDB DAX, click the 【Install】 button, and follow the prompts to complete the installation.

Manual Enablement Script¶

1. Log in to the Func console, click 【Script Market】, enter the official script market, and search for guance_aws_dynamodb_dax.
2. After clicking 【Install】, input the corresponding parameters: AWS AK ID, AK Secret, and account name.
3. Click 【Deploy Startup Script】, and the system will automatically create a Startup Measurement set and automatically configure the corresponding startup script.
4. After enabling, you can see the corresponding automatic trigger configuration in 「Manage / Auto Trigger Configuration」. Click 【Execute】 to immediately execute once without waiting for the scheduled time. Wait a moment, and you can view the execution task records and corresponding logs.

Verification¶

1. In 「Manage / Auto Trigger Configuration」, confirm whether the corresponding tasks have the corresponding automatic trigger configurations. You can also view the corresponding task records and logs to check for any anomalies.
2. In Guance, under 「Infrastructure / Custom」, check if there is any asset information.
3. In Guance, under 「Metrics」, check if there are corresponding monitoring data.

Metrics¶

After configuring Amazon Cloud Monitoring, the default Measurement sets are as follows. You can collect more Metrics through configuration:
