AWS Lambda¶

The displayed Metrics for AWS Lambda include cold start time, execution time, concurrent executions, and memory usage. These Metrics reflect the response speed, scalability, and resource utilization of Lambda functions.

Configuration¶

Install Func¶

It is recommended to activate the TrueWatch Integration - Extensions - DataFlux Func (Automata): All prerequisites are automatically installed, please proceed with the script installation.

If deploying Func manually, refer to Manual Deployment of Func

Install 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)

Automated Script Activation¶

1. Log in to the TrueWatch console
2. Click on the 【Integration】 menu, select 【Cloud Account Management】
3. Click on 【Add Cloud Account】, select 【AWS】, and fill in the required information on the interface. If the cloud account information has been configured before, skip this step.
4. Click on 【Test】, and if the test is successful, click on 【Save】. If the test fails, please check the relevant configuration information and retest.
5. Click on the 【Cloud Account Management】 list to view the added cloud account, click on the corresponding cloud account to enter the details page.
6. Click on the 【Integration】 button on the cloud account details page, find AWS Lambda under the Not Installed list, and click on the 【Install】 button to install it.

Manual Script Activation¶

1. Log in to the Func console, click on 【Script Market】, enter the TrueWatch script market, and search for: integration_aws_lambda

2. Click on 【Install】, and enter the corresponding parameters: AWS AK ID, AK Secret, and account name.

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

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

Verification¶

1. In 「Management / Automatic Trigger Configuration」, confirm whether the corresponding task has the corresponding automatic trigger configuration, and you can also check the corresponding task records and logs for any anomalies.
2. In TrueWatch, 「Infrastructure / Custom」, check if there is asset information.
3. In TrueWatch, 「Metrics」, check if there is corresponding monitoring data.

Metrics¶

After configuring Amazon CloudWatch, the default Measurement is as follows. More Metrics can be collected through configuration:

Amazon CloudWatch Lambda Metrics Details

Invocation Metrics¶

Performance Metrics¶

Performance Metrics provide detailed information about the performance of individual function invocations. For example, the Duration metric indicates the amount of time (in milliseconds) the function spends processing an event. To understand how quickly your function processes events, view these Metrics using the Average or Max statistics.

Concurrency Metrics¶

Lambda reports concurrency Metrics as a total count of instances processing events across functions, versions, aliases, or AWS regions. To see how close you are to the concurrency limit, view these Metrics using the Max statistics.

Asynchronous Invocation Metrics¶

Asynchronous invocation Metrics provide detailed information about asynchronous invocations from event sources and direct invocations. You can set thresholds and alarms to notify you of certain changes. For example, when the number of events queued for processing increases unexpectedly (AsyncEventsReceived). Or, when an event has been waiting a long time to complete processing (AsyncEventAge).

Object¶

The collected AWS Lambda object data structure can be seen in 「Infrastructure - Custom」.
