Hi all. I’m working on deploying multiple sites via the

nextjsSite

construct and it works like a charm, the problem I’m facing is adding Cloudwatch alarms to the lambda’s this construct creates. My assumption was that

getAllFunctions

would help here but the construct doesn’t return this method and using it as I have below doesn’t return any functions. Any suggestions would be great.

// js
import * as sst from "@serverless-stack/resources";
import * as CDK from "aws-cdk-lib";
import * as cloudwatch from "aws-cdk-lib/aws-cloudwatch";
import * as cw_actions from "aws-cdk-lib/aws-cloudwatch-actions";
import * as sns from "aws-cdk-lib/aws-sns";
import * as chatbot from "aws-cdk-lib/aws-chatbot";

export default class BrandStack extends sst.Stack {
  constructor(scope, id, props) {
    super(scope, id, props);

    const site = new sst.NextjsSite(this, props.brand, {
      path: "./",
      environment: {
        NEXT_PUBLIC_BRAND: props.brand,
      },
    });

    // Get all functions created by the NextjsSite construct
    const functions = this.getAllFunctions();

    // Add metric and alarm for each lambda to catch errors
    functions.forEach((fn) => {
      const fnName = fn.functionName || "lambda";

      // Configure metric for errors
      const fnErrors = fn.metricErrors({
        period: CDK.Duration.minutes(1),
      });

      // configure alarm
      new cloudwatch.Alarm(this, `${fnName}-errors-alarm"}`, {
        metric: fnErrors,
        threshold: 1,
        comparisonOperator:
          cloudwatch.ComparisonOperator.GREATER_THAN_OR_EQUAL_TO_THRESHOLD,
        evaluationPeriods: 1,
        alarmDescription: `Errors for ${fnName}`,
      });

      // Send alert
      const topic = new sns.Topic(this, `${fnName}-Topic`);
      cloudwatch.Alarm.addAlarmAction(new cw_actions.SnsAction(topic));

      // Configure slack connection
      new chatbot.SlackChannelConfiguration(this, `${fnName}-SlackChannel`, {
        slackChannelConfigurationName: "sites-alerts-dev",
        slackChannelId: "C02VD7K1X6G",
        slackWorkspaceId: "T52H878E7",
        notificationTopics: [topic],
        loggingLevel: chatbot.LoggingLevel.ERROR,
      });
    });

    this.addOutputs({
      URL: site.url,
    });
  }
}

Hey @Adie Williams, let me take a look, I think we can expose the functions as the construct properties, so you can do:

const site = new sst.NextjsSite(...);
site.apiFunction;

Thanks for the clarification @Frank, unfortunately

site.apiFunction

is returning

undefined

@Adie Williams I think @Frank meant more that we could implement that property and cut a new release.

Thanks @Jay, that makes more sense 🤦 . That would be great 👍

No worries! @Frank just brining this up.
