# 使用 AWS CLI 指定日志传输
<a name="CLI_Log"></a>

**慢日志**

创建将慢日志传输到 CloudWatch Logs 的复制组。

对于 Linux、macOS 或 Unix：

```
aws elasticache create-replication-group \
    --replication-group-id test-slow-log \
    --replication-group-description test-slow-log \
    --engine redis \
    --cache-node-type cache.r5.large \
    --num-cache-clusters 2 \
    --log-delivery-configurations '{
        "LogType":"slow-log", 
        "DestinationType":"cloudwatch-logs",  
        "DestinationDetails":{ 
          "CloudWatchLogsDetails":{ 
            "LogGroup":"my-log-group"
          } 
        }, 
        "LogFormat":"json" 
      }'
```

对于 Windows：

```
aws elasticache create-replication-group ^
    --replication-group-id test-slow-log ^
    --replication-group-description test-slow-log ^
    --engine redis ^
    --cache-node-type cache.r5.large ^
    --num-cache-clusters 2 ^
    --log-delivery-configurations '{
        "LogType":"slow-log", 
        "DestinationType":"cloudwatch-logs", 
        "DestinationDetails":{ 
          "CloudWatchLogsDetails":{ 
            "LogGroup":"my-log-group"
          } 
        }, 
        "LogFormat":"json" 
      }'
```

修改复制组以将慢日志传输到 CloudWatch Logs

对于 Linux、macOS 或 Unix：

```
aws elasticache modify-replication-group \
    --replication-group-id test-slow-log \
    --apply-immediately \
    --log-delivery-configurations '
    {
      "LogType":"slow-log", 
      "DestinationType":"cloudwatch-logs", 
      "DestinationDetails":{ 
        "CloudWatchLogsDetails":{ 

          "LogGroup":"my-log-group"
        } 
      },
      "LogFormat":"json" 
    }'
```

对于 Windows：

```
aws elasticache modify-replication-group ^
    --replication-group-id test-slow-log ^
    --apply-immediately ^
    --log-delivery-configurations '
    {
      "LogType":"slow-log", 
      "DestinationType":"cloudwatch-logs", 
      "DestinationDetails":{ 
        "CloudWatchLogsDetails":{ 
          "LogGroup":"my-log-group"
        } 
      },
      "LogFormat":"json" 
    }'
```

修改复制组以禁用慢日志传递

对于 Linux、macOS 或 Unix：

```
aws elasticache modify-replication-group \
    --replication-group-id test-slow-log \
    --apply-immediately \
    --log-delivery-configurations ' 
    {
      "LogType":"slow-log", 
      "Enabled":false 
    }'
```

对于 Windows：

```
aws elasticache modify-replication-group ^
    --replication-group-id test-slow-log ^
    --apply-immediately ^
    --log-delivery-configurations '  
    {
      "LogType":"slow-log", 
      "Enabled":false 
    }'
```

**引擎日志**

创建将引擎日志传输到 CloudWatch Logs 的复制组。

对于 Linux、macOS 或 Unix：

```
aws elasticache create-replication-group \
    --replication-group-id test-slow-log \
    --replication-group-description test-slow-log \
    --engine redis \
    --cache-node-type cache.r5.large \
    --num-cache-clusters 2 \
    --log-delivery-configurations '{
        "LogType":"engine-log", 
        "DestinationType":"cloudwatch-logs",  
        "DestinationDetails":{ 
          "CloudWatchLogsDetails":{ 
            "LogGroup":"my-log-group"
          } 
        }, 
        "LogFormat":"json" 
      }'
```

对于 Windows：

```
aws elasticache create-replication-group ^
    --replication-group-id test-slow-log ^
    --replication-group-description test-slow-log ^
    --engine redis ^
    --cache-node-type cache.r5.large ^
    --num-cache-clusters 2 ^
    --log-delivery-configurations '{
        "LogType":"engine-log", 
        "DestinationType":"cloudwatch-logs", 
        "DestinationDetails":{ 
          "CloudWatchLogsDetails":{ 
            "LogGroup":"my-log-group"
          } 
        }, 
        "LogFormat":"json" 
      }'
```

修改复制组以将引擎日志传送到 Firehose

对于 Linux、macOS 或 Unix：

```
aws elasticache modify-replication-group \
    --replication-group-id test-slow-log \
    --apply-immediately \
    --log-delivery-configurations '
    {
      "LogType":"engine-log", 
      "DestinationType":"kinesis-firehose",
      "DestinationDetails":{
      "KinesisFirehoseDetails":{
         "DeliveryStream":"test"
       }    
     },
      "LogFormat":"json" 
    }'
```

对于 Windows：

```
aws elasticache modify-replication-group ^
    --replication-group-id test-slow-log ^
    --apply-immediately ^
    --log-delivery-configurations '
    {
      "LogType":"engine-log",       
      "DestinationType":"kinesis-firehose",
      "DestinationDetails":{
      "KinesisFirehoseDetails":{
         "DeliveryStream":"test"
       }  
      },
      "LogFormat":"json" 
    }'
```

修改复制组以切换到引擎格式

对于 Linux、macOS 或 Unix：

```
aws elasticache modify-replication-group \
    --replication-group-id test-slow-log \
    --apply-immediately \
    --log-delivery-configurations ' 
    {
       "LogType":"engine-log",
       "LogFormat":"json"
    }'
```

对于 Windows：

```
aws elasticache modify-replication-group ^
    --replication-group-id test-slow-log ^
    --apply-immediately ^
    --log-delivery-configurations ' 
    {
       "LogType":"engine-log",
       "LogFormat":"json"
    }'
```

修改复制组以禁用引擎日志传递

对于 Linux、macOS 或 Unix：

```
aws elasticache modify-replication-group \
    --replication-group-id test-slow-log \
    --apply-immediately \
    --log-delivery-configurations ' 
    {
      "LogType":"engine-log", 
      "Enabled":false 
    }'
```

对于 Windows：

```
aws elasticache modify-replication-group ^
    --replication-group-id test-slow-log ^
    --apply-immediately ^
    --log-delivery-configurations '  
    {
      "LogType":"engine-log", 
      "Enabled":false 
    }'
```
