Simple connector for AWS Lambda with Cloudwatch

lambda-conector is a simple client AWS Lambda with CloudWatch for check invocations and error occurred in a time interval.

This version requires a minimum version of Go 1.15.

Getting started

To get started working with this conector setup your project for Go modules, and retrieve this project's dependencies with go get.

Initialize Project

$ mkdir hello-lambda-conector
$ cd hello-lambda-conector
$ go mod init hello-lambda-conector

Add lambda-conector Dependencies

$ go get github.com/elvenworks/lambda-conector

Operations available for this version

What operations can this connector perform?

Fetches the sum of invocations and errors of a function for a given period. If the informed period does not have invocations, a new check of the last 24 hours will be carried out to obtain the last calls

Usage - GetLastLambdaRun

Return 'LambdaLastRun' | 'error' :

type LambdaLastRun struct {
    Timestamp  time.Time
    ErrorCount float64
    Message    string
}

Write Code

In your preferred editor add the following content to main.go

package main

import (
	lambdaconector "github.com/elvenworks/lambda-conector"
	"github.com/sirupsen/logrus"
)

func main() {

    // Initialize the AWS SDK with or Settings
    config := lambdaconector.InitConfig{
		AccessKeyID:     "",
		SecretAccessKey: "",
		Region:          "",
		FunctionName:    "",
		Period:          60,
		FlagSearchPeriod: false,
	}
	lamdba := lambdaconector.InitLambda(config)

	lambdaLastRun, err := lamdba.GetLastLambdaRun()
	if err != nil {
		logrus.Error(err)
		return
	}
	logrus.Info("last execution: ", lambdaLastRun.Timestamp)
	logrus.Info("message: ", lambdaLastRun.Message)
	logrus.Info("errors: ", lambdaLastRun.ErrorCount)
