Laravel 5.6 aws cloudwatch日志

时间：2018-06-12 09:59:51

标签： php laravel amazon-web-services amazon-cloudwatch

升级的laravel从5.4到5.6。 Laravel从5.6版开始删除了$ app-＆gt; configureMonologUsing

aws的教程不再适用。 https://aws.amazon.com/tw/blogs/developer/php-application-logging-with-amazon-cloudwatch-logs-and-monolog/

任何人都可以告诉我在$ app-＆gt; configureMonologUsing中迁移逻辑的位置？

感谢

使用以下命令安装最新版本的CloudWatch处理程序库：

composer require maxbanton/cwh

您可以在custom中添加一个config/logging.php频道，例如：

'cloudwatch' => [
  'driver' => 'custom',
  'via' => \App\Logging\CloudWatchLoggerFactory::class,
  'sdk' => [
    'region' => env('AWS_DEFAULT_REGION', 'us-east-1'),
    'version' => 'latest',
    'credentials' => [
      'key' => env('AWS_ACCESS_KEY_ID'),
      'secret' => env('AWS_SECRET_ACCESS_KEY')
    ]
  ],
  'retention' => env('CLOUDWATCH_LOG_RETENTION',7),
  'level' => env('CLOUDWATCH_LOG_LEVEL','error')
],

和工厂类App/Logging/CloudWatchLoggerFactory.php如下：

<?php

namespace App\Logging;

use Aws\CloudWatchLogs\CloudWatchLogsClient;
use Maxbanton\Cwh\Handler\CloudWatch;
use Monolog\Logger;

class CloudWatchLoggerFactory
{
    /**
     * Create a custom Monolog instance.
     *
     * @param  array  $config
     * @return \Monolog\Logger
     */
    public function __invoke(array $config)
    {
        $sdkParams = $config["sdk"];
        $tags = $config["tags"] ?? [ ];
        $name = $config["name"] ?? 'cloudwatch';

        // Instantiate AWS SDK CloudWatch Logs Client
        $client = new CloudWatchLogsClient($sdkParams);

        // Log group name, will be created if none
        $groupName = config('app.name') . '-' . config('app.env');

        // Log stream name, will be created if none
        $streamName = config('app.hostname');

        // Days to keep logs, 14 by default. Set to `null` to allow indefinite retention.
        $retentionDays = $config["retention"];

        // Instantiate handler (tags are optional)
        $handler = new CloudWatch($client, $groupName, $streamName, $retentionDays, 10000, $tags);

        // Create a log channel
        $logger = new Logger($name);
        // Set handler
        $logger->pushHandler($handler);

        return $logger;
    }
}

如果您在ECS上使用Laravel。

在.env文件中添加此LOG_CHANNEL=stderr

它将自动登录到CloudWatch。

答案 2 :(得分：1)

如果您在AWS EC2实例上运行并记录大量信息/调试消息，则实时发送日志会减慢您的应用程序响应时间。相反，您可以让CloudWatch代理查看您的laravel.log，以每5秒发送一次新的日志条目。 CloudWatch代理可以运送您的所有系统日志和任何系统指标（例如CPU），以便您创建云监视警报。

CloudWatch Agent

答案 3 :(得分：1)

我想分享一下我为Laravel和Nginx日志实现Cloudwatch的经验。本指南将与使用Elastic Beanstalk的Multicontainer Docker环境相关。我的方法更多地与流日志相关，而不是手动添加日志。

以下是步骤：

1。

添加.ebextensions/1_cloudwatch.config文件，其内容如下：

option_settings:
  - namespace: aws:elasticbeanstalk:cloudwatch:logs
    option_name: StreamLogs
    value: true

这将打开默认实例日志流（根据docs）。

2。

添加.ebextensions/2_logs_streamtocloudwatch_linux.config文件，其内容如下：

###################################################################################################
#### The following file installs and configures the AWS CloudWatch Logs agent to push logs to a Log
#### Group in CloudWatch Logs.
#### 
#### The configuration below sets the logs to be pushed, the Log Group name to push the logs to and
#### the Log Stream name as the instance id. The following files are examples of logs that will be
#### streamed to CloudWatch Logs in near real time:
#### 
#### 
#### You can then access the CloudWatch Logs by accessing the AWS CloudWatch Console and clicking
#### the "Logs" link on the left. The Log Group name will follow this format:
####
#### /aws/elasticbeanstalk/<environment name>/<full log name path>
####
#### Please note this configuration can be used additionally to the "Log Streaming" feature:
#### http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/AWSHowTo.cloudwatchlogs.html
###################################################################################################

packages:
  yum:
    awslogs: []

files:
  "/etc/awslogs/awscli.conf" :
    mode: "000600"
    owner: root
    group: root

      [plugins]
      cwlogs = cwlogs

      log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "var/log/nginx-access"]]}`
      log_stream_name = logs
      timestamp_format = '[%d/%b/%Y:%H:%M:%S %z]'
      file = /var/log/nginx/access.log
      buffer_duration = 5000
      use_gzip_http_content_encoding = true

      [/var/log/nginx/laravel]
      datetime_format = %Y-%m-%d %H:%M:%S
      log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "var/log/laravel"]]}`
      log_stream_name = logs
      timestamp_format = '[%Y-%m-%d %H:%M:%S]'
      file = /var/log/laravel/laravel-*.log
      buffer_duration = 5000
      use_gzip_http_content_encoding = true
      multi_line_start_pattern = {datetime_format}

commands:
  "01":
    command: chkconfig awslogs on
  "02":
    command: service awslogs restart

该脚本由Amazon提供，这是源文件-https://github.com/awsdocs/elastic-beanstalk-samples/blob/master/configuration-files/aws-provided/instance-configuration/logs-streamtocloudwatch-linux.config

这里最有趣的部分是这个：

[/var/log/laravel]
datetime_format = %Y-%m-%d %H:%M:%S
log_group_name = `{"Fn::Join":["/", ["/aws/elasticbeanstalk", { "Ref":"AWSEBEnvironmentName" }, "var/log/laravel"]]}`
log_stream_name = logs
timestamp_format = '[%Y-%m-%d %H:%M:%S]'
file = /var/log/laravel/laravel-*.log
buffer_duration = 5000
use_gzip_http_content_encoding = true
multi_line_start_pattern = {datetime_format}

这些是我们用于Laravel日志记录的参数。这里没什么特别的。

  • log_group_name-云监视日志组名称，您可以在此处设置一些简单的内容，例如：production-laravel
  • log_stream_name-组的流的名称，您可以在此处设置任何字符串，也可以传递以下“变量”：{instance_id}，{hostname}，{ip_address}，而不是静态字符串
  • multi_line_start_pattern = {datetime_format}-我们需要这样做，以防止从日志文件中为每一行创建新的日志记录

您可以在CloudWatch Agent参考-https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AgentReference.html

中了解有关这些参数的更多信息。

我们需要更新Dockerrun.aws.json。

在您的volumes部分，您需要添加以下项目：

"volumes": [
    ...
    {
        "name": "awseb-logs-nginx-proxy",
        "host": {
            "sourcePath": "/var/log/nginx"
        }
    },
    {
        "name": "laravel-logs",
        "host": {
            "sourcePath": "/var/log/laravel"
        }
    }
    ...
]

第二，我们需要更新containerDefinitions部分，并为所需的容器添加mountPoints，例如：

"containerDefinitions": [
    ...
    {
        "name": "laravel-app",
        "image": "laravel-image",
        "hostname": "laravel",            
        "essential": true,
        "memory": 256,
        "mountPoints": [
            {
                "sourceVolume": "laravel-logs",
                "containerPath": "/var/www/storage/logs"
            }
        ]    
    },
    {
        "name": "nginx",
        "image": "nginx-image",
        "hostname": "nginx",
        "essential": true,
        "memory": 128,
        "volumesFrom": [
            {
                "sourceContainer": "app"
            }
        ],
        "portMappings": [
            {
                "hostPort": 80,
                "containerPort": 80
            }
        ],
        "mountPoints": [
            {
                "sourceVolume": "awseb-logs-nginx-proxy",
                "containerPath": "/var/log/nginx"
            }
        ],
        "links": ["laravel-app"]
    }
    ...
]

结果，您的Dockerrun.aws.json文件可能看起来像这样：

{
    "AWSEBDockerrunVersion": 2,
    "volumes": [
        {
            "name": "awseb-logs-nginx-proxy",
            "host": {
                "sourcePath": "/var/log/nginx"
            }
        },
        {
            "name": "laravel-logs",
            "host": {
                "sourcePath": "/var/log/laravel"
            }
        }
    ],
    "containerDefinitions": [
        {
            "name": "laravel-app",
            "image": "laravel-image",
            "hostname": "laravel",            
            "essential": true,
            "memory": 256,
            "mountPoints": [
                {
                    "sourceVolume": "laravel-logs",
                    "containerPath": "/var/www/storage/logs"
                }
            ] 
        },
        {
            "name": "nginx",
            "image": "nginx-image",
            "hostname": "nginx",
            "essential": true,
            "memory": 128,
            "volumesFrom": [
                {
                    "sourceContainer": "app"
                }
            ],
            "portMappings": [
                {
                    "hostPort": 80,
                    "containerPort": 80
                }
            ],
            "mountPoints": [
                {
                    "sourceVolume": "awseb-logs-nginx-proxy",
                    "containerPath": "/var/log/nginx"
                }
            ],
            "links": ["laravel-app"]
        }        
    ]    
}

您需要检查是否允许您的IAM实例配置文件角色将日志添加到CloudWatch。默认情况下，角色的名称为aws-elasticbeanstalk-ec2-role，但是您可以在环境的“配置”页面的“安全性”部分下对其进行检查。

这是您需要添加的策略（source）：

{
"Version": "2012-10-17",
"Statement": [
  {
    "Effect": "Allow",
    "Action": [
      "logs:CreateLogGroup",
      "logs:CreateLogStream",
      "logs:PutLogEvents",
      "logs:DescribeLogStreams"
    ],
    "Resource": [
      "arn:aws:logs:*:*:*"
    ]
  }
 ]
}

或者您也可以添加CloudWatchLogsFullAccess策略以用于测试。

结果，您将收到以下日志组：

  • / aws / elasticbeanstalk / your-env-name / var / log / laravel
  • / aws / elasticbeanstalk / your-env-name / var / log / nginx-access
  • / aws / elasticbeanstalk / your-env-name / var / log / nginx-error
