无法使用 PHP 登录 AWS Cloudwatch？

Question

I am using PHP to log something over cloudwatch, my application is deployed over AWS Elastic Beanstalk. I followed the AWS Dev Doc, I tried to implement all the things that have defined there but still I didn't get anything logged over cloudwatch neither on beanstalk logs. The log file are creating in my local system with all the logs in it, what is the issue there? someone please help me.

Code -

<?php
use Aws\CloudWatchLogs\CloudWatchLogsClient;
use Maxbanton\Cwh\Handler\CloudWatch;
use Monolog\Logger;
use Monolog\Formatter\LineFormatter;
use Monolog\Handler\StreamHandler;
use Monolog\Handler\SyslogHandler;

$logFile = "testapp_local.log";
$appName = "TestApp01";
$facility = "local0";

$awsCredentials = [
'region' => 'eu-east-2',
'version' => 'latest',
'credentials' => [
'key' => 'KEY',
'secret' => 'Secret KEY'
]
];

$cwClient = new CloudWatchLogsClient($awsCredentials);
// Log group name, will be created if none
$cwGroupName = 'php-applog-test#--1';

// Log stream name, will be created if none
$cwStreamNameInstance = 'some-stream-name-EC2-instance-1';
// Instance ID as log stream name
$cwStreamNameApp = "TestAuthenticationApp";
// Days to keep logs, 14 by default
$cwRetentionDays = 90;

$cwHandlerInstanceNotice = new CloudWatch($cwClient, $cwGroupName, $cwStreamNameInstance, $cwRetentionDays, 10000, [ 'application' => 'DemoFormTwo' ],Logger::NOTICE);
$cwHandlerInstanceError = new CloudWatch($cwClient, $cwGroupName, $cwStreamNameInstance, $cwRetentionDays, 10000, [ 'application' => 'DemoFormTwo' ],Logger::ERROR);
$cwHandlerAppNotice = new CloudWatch($cwClient, $cwGroupName, $cwStreamNameApp, $cwRetentionDays, 10000, [ 'application' => 'DemoFormTwo' ],Logger::NOTICE);

$logger = new Logger('PHP Logging');

$formatter = new LineFormatter(null, null, false, true);
$syslogFormatter = new LineFormatter("%channel%: %level_name%: %message% %context% %extra%",null,false,true);
$infoHandler = new StreamHandler(__DIR__."/".$logFile, Logger::INFO);
$infoHandler->setFormatter($formatter);

$warnHandler = new SyslogHandler($appName, $facility, Logger::WARNING);
$warnHandler->setFormatter($syslogFormatter);

$cwHandlerInstanceNotice->setFormatter($formatter);
$cwHandlerInstanceError->setFormatter($formatter);
$cwHandlerAppNotice->setFormatter($formatter);

$logger->pushHandler($warnHandler);
$logger->pushHandler($infoHandler);
$logger->pushHandler($cwHandlerInstanceNotice);
$logger->pushHandler($cwHandlerInstanceError);
$logger->pushHandler($cwHandlerAppNotice);

$logger->info('Initial test of application logging.');
$logger->warn('Test of the warning system logging.');
$logger->notice('Application Auth Event: ',[ 'function'=>'login-action','result'=>'login-success' ]);
$logger->notice('Application Auth Event: ',[ 'function'=>'login-action','result'=>'login-failure' ]);
$logger->error('Application ERROR: System Error');
?>

I have installed

curl -sS https://getcomposer.org/installer | php
php composer.phar require aws/aws-sdk-php
php composer.phar require monolog/monolog
php composer.phar require maxbanton/cwh:^1.0

These dependencies on the beanstalk. I am using monolog (composer) as given in the doc example. The issue here is the logs are generating just in my local system but not in the Cloudwatch how can I make them appear over CW ?

Answer 1

Looks like there is an issue with how credentials must be sent: if you are not using the profile key and also you don't have an AWS credential file in your $HOME the connection to CloudWatch is not made.

To avoid that validation try this:

$awsCredentials = [
'use_aws_shared_config_files' => false,
'region' => 'eu-east-2',
'version' => 'latest',
'credentials' => [
'key' => 'KEY',
'secret' => 'Secret KEY'
]
];

By the way, use_aws_shared_config_files works with true or false .

We have those versions on composer.json :

"aws/aws-sdk-php": "^3.24",
 "monolog/monolog": "^2.6",
 "maxbanton/cwh": "^2.0"
