Creating a Function Using a Template

Introduction

FunctionGraph provides templates to automatically complete code and running environment configurations when you create a function, helping you quickly build applications.

Step 1: Prepare the Environment

To perform the operations described in this section, ensure that you have the FunctionGraph FullAccess permissions, that is, all permissions for FunctionGraph. For more information, see section "Permissions Management".

Step 2: Create a Function

2. Click Create Function in the upper right corner and choose Select template.
3. Select the template shown in Figure 1 and click Configure.

4. Set Function Name to context, select any agency from the Agency drop-down list, retain default values for other parameters, and click Create Function.
   

   • If no agency is configured, the following message will be displayed when the function is triggered:

     Failed to access other services because no temporary AK, SK, or token has been obtained. Please set an agency.

Step 5: View Monitoring Metrics

On the function details page, click the Monitoring tab.

• On the Monitoring tab page, choose Metrics, and select a time range (such as 5 minutes, 15 minutes, or 1 hour) to query the function.
• The following metrics are displayed: invocations, errors, duration (including the maximum, average, and minimum durations), and throttles.

Step 6: Delete a Function
