将 laravel从 5.4 升级到 5.6。 Laravel从5.6版本开始删除$app->configureMonolog使用
来自 AWS 的教程不再适用。 https://aws.amazon.com/tw/blogs/developer/php-application-logging-with-amazon-cloudwatch-logs-and-monolog/
任何人都可以建议我在哪里迁移$app>配置MonologUsing中的逻辑？
谢谢
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config/logging.php中添加custom通道，如下所示：
'cloudwatch' => [
'driver' => 'custom',
'via' => AppLoggingCloudWatchLoggerFactory::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')
],
工厂类App/Logging/CloudWatchLoggerFactory.php为：
<?php
namespace AppLogging;
use AwsCloudWatchLogsCloudWatchLogsClient;
use MaxbantonCwhHandlerCloudWatch;
use MonologLogger;
class CloudWatchLoggerFactory
{
/**
* Create a custom Monolog instance.
*
* @param array $config
* @return MonologLogger
*/
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 AWS ECS 上使用 Laravel。
在.env文件中添加此LOG_CHANNEL=stderr
它会在您配置任务定义时将日志写入 CloudWatch。
如果您在 AWS EC2 实例上运行并记录大量信息/调试消息，则实时发送日志可能会减慢应用程序响应时间。相反，您可以让 CloudWatch 代理监视您的 laravel.log以发送新的日志条目，即每 5 秒发送一次。CloudWatch 代理可以传送您的所有系统日志和任何系统指标(如 CPU(，以便您可以创建云监视警报。

我想分享我为 Laravel和 Nginx 日志实现 Cloudwatch 的经验。本指南将与使用 Elastic Beanstalk 的多容器 Docker 环境相关。我的方法更多地与流式传输日志相关，而不是手动添加它们。
以下是步骤：
1.
添加.ebextensions/1_cloudwatch.config包含以下内容的文件：
option_settings:
- namespace: aws:elasticbeanstalk:cloudwatch:logs
option_name: StreamLogs
value: true
这将打开默认实例日志流式处理(根据文档(。
阿拉伯数字。
添加.ebextensions/2_logs_streamtocloudwatch_linux.config包含以下内容的文件：
###################################################################################################
#### 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

use_gzip_http_content_encoding = true
multi_line_start_pattern = {datetime_format}
commands:
"01":
command: chkconfig awslogs on
"02":
command: service awslogs restart
此脚本由亚马逊提供，这里是来源 - 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东西，例如：
production-laravel - log_stream_name - 组流的名称，您可以在此处设置任何字符串，也可以传递这些"变量"：{instance_id}，{主机名}，{ip_address}而不是静态字符串
- multi_line_start_pattern = {datetime_format} - 我们需要它来防止从我们的日志文件中为每一行创建新的日志记录
您可以在 CloudWatch 代理参考 - https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AgentReference.html
3.
我们需要更新我们的Dockerrun.aws.json.
在"volumes"部分中，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"
}
}
...
]
其次，我们需要更新我们的containerDefinitions部分并为所需的容器添加mountPoints，如下所示：
"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"]
}
...
]
因此，您的Dockerrun.aws.json文件可能如下所示：
{
"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"]
}
]
}
4.
您需要检查是否允许您的 IAM 实例配置文件角色向 CloudWatch 添加日志。默认情况下，角色的名称为aws-elasticbeanstalk-ec2-role，但您可以在环境的"配置"页上的"安全"部分下进行检查。
以下是您需要添加的策略(来源(：
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": [
"logs:CreateLogGroup",
"logs:CreateLogStream",
"logs:PutLogEvents",
"logs:DescribeLogStreams"
],
"Resource": [
"arn:aws:logs:*:*:*"
]
}
]
}
或者，您可以添加仅用于测试CloudWatchLogsFullAccess策略。
因此，您将收到如下日志组：
/- 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
