Aws-Cloudwatch添加监控

1、搜索IAM

2、创建角色

3、在红框内搜索策略Cloudwatchagent

4、起个名字点击创建

5、控制台选中实例绑定IAM角色

6、登录到EC2实例,安装和配置CloudWatchAgent

下载：

wget - https://s3.amazonaws.com/amazoncloudwatch-agent/amazon_linux/amd64/latest/amazon-cloudwatch-agent.rpm

7、安装

rpm -U ./amazon-cloudwatch-agent.rpm

8、进入/opt/aws/amazon-cloudwatch-agent/doc/

vim amazon-cloudwatch-agent.json 添加监控项 可自定义

              },
              {
                "file_path": "/opt/aws/amazon-cloudwatch-agent/logs/test.log",

              }
            ]
          }
        },
        "log_stream_name": "my_log_stream_name",
        "force_flush_interval" : 15
      }
    }

9、删除原/opt/aws/amazon-cloudwatch-agent/doc/amazon-cloudwatch-agent-schema.json

将上面新建的amazon-cloudwatch-agent.json更改为amazon-cloudwatch-agent-schema.json

mv amazon-cloudwatch-agent.json amazon-cloudwatch-agent-schema.json

10、启动cloudwatch-agent

/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -m ec2 -s -c file:/opt/aws/amazon-cloudwatch-agent/doc/amazon-cloudwatch-agent-schema.json

11、检查是否启动成功

/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -m ec2 -a status

12、登录cloudwatch控制台，查看监控指标

复制实例ID在全部指标中查询

13、查看内存监控

14、注释
