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 activate TrueWatch integration - extension - DataFlux Func (Automata): All prerequisites will be automatically installed, please continue with the script installation.

If you deploy Func yourself, refer to Self-deployed Func

Installation Script¶

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

To synchronize monitoring data for AWS-DynamoDB DAX, we install the corresponding collection script: "TrueWatch Integration (AWS-DynamoDB DAX Collection)" (ID: truewatch_aws_dynamodb_dax)

After clicking [Install], enter the corresponding parameters: AWS AK ID, AWS AK SECRET, account_name.

Click [Deploy Startup Script], and the system will automatically create a Startup script set and automatically configure the corresponding startup script. In the startup script, ensure that 'regions' matches the actual regions where the instances are located.

Once activated, you can see the corresponding automatic trigger configuration under "Manage / Automatic Trigger Configuration." Click [Execute] to immediately run it once without waiting for the scheduled time. After a short while, you can view the execution task records and corresponding logs.

If you want to collect corresponding logs, you also need to enable the corresponding log collection script. If you want to collect billing information, you need to enable the cloud billing collection script.

We default to collecting some configurations, see the Metrics column for details Configuration Custom Cloud Object Metrics

Verification¶

1. Confirm in "Manage / Automatic Trigger Configuration" whether the corresponding task has the corresponding automatic trigger configuration, and you can check the corresponding task records and logs to check for any abnormalities.
2. On the TrueWatch platform, check under "Infrastructure / Custom" whether asset information exists.
3. On the TrueWatch platform, check under "Metrics" whether there are corresponding monitoring data.

Metrics¶

After configuring Amazon CloudWatch, the default Measurement set is as follows. You can collect more Metrics through configuration:
