cat消息树

结构

在同一个线程里，产生的各个埋点会串联成一个消息树。

private ByteBuf m_buf;

// 服务名称
private String m_domain;

// 主机名
private String m_hostName;

// ip地址
private String m_ipAddress;

// transaction信息
private Message m_message;

// 消息id
private String m_messageId;

// 父消息id
private String m_parentMessageId;

// 根消息id
private String m_rootMessageId;

private String m_sessionToken;

// 线程组名称
private String m_threadGroupName;

// 线程id
private String m_threadId;

// 线程名称
private String m_threadName;

private boolean m_sample = true;

MessageTree经过编码之后如下：

PT1	web-a	PPC202007150330	10.10.141.70	main	71	http-nio-8080-exec-9	web-b-0a0a8d46-444200-57	web-b-0a0a8d46-444200-56	web-b-0a0a8d46-444200-56	null

消息头

  • 第一行为消息头。
  • 字段依次为：version、domain、hostName、 ipAdress、 treadGroupName、 treadId、 threadName、 MessageId、 parentMessageId、 rootMessageId、 sessionToken。
  • 字段之间以"\t"分隔，并以"\n"结尾。
  • 空用null表示。

消息体

不同类型的消息有不同的标识。

t：Transaction开始
T：Transaction结束
E：Event
H：Heartbeat
M：Metric

http调用

例如有两个web应用：web-b、web-a。

1、web-a中有接口/api/findById-a

2、web-b中有接口/api/findById-b，这个接口内部会去调web-a的/api/findById-a接口

当调用/api/findById-b接口时，各个应用的报文如下所示。

web-b 报文如下：
