是否有针对NATS协议的wireshark分析器(https://nats.io/)

Question

到目前为止，Wireshark仅显示捕获的TCP有效负载中的原始字节。我希望看到一些结构化的NATS消息:连接、订阅、发布等。有没有Wireshark插件可以做到这一点？或者是另一个我能用到的嗅探器？

Answer 1

NATS使用ASCII文本。您只需在顶部面板中右键单击一条消息，选择Follow->>TCP Stream。它将显示一个如下所示的弹出窗口：

INFO {"server_id":"NBJQ7WOATUJACQOLGFHQWXIZHYSSTR5ACGUPKRUUURQVJJ5YZ7GG4KO7","server_name":"NBJQ7WOATUJACQOLGFHQWXIZHYSSTR5ACGUPKRUUURQVJJ5YZ7GG4KO7","version":"2.1.6","proto":1,"git_commit":"8c8d6f8","go":"go1.13.9","host":"0.0.0.0","port":4222,"max_payload":1048576,"client_id":3,"client_ip":"10.2.125.91"}

唯一的缺点是它一次只显示一个TCP连接。您可以通过以下方式列出所有TCP连接: Menu: Statistics->>Conversations并选择TCP选项卡。
