jstack java stack tracing tool

jstack java stack tracing tool 1. Introduction to jstack jstack (stack trace for java) is a stack tracing tool that comes with the Java virtual machine. jstack is mainly used to generate a thread snapshot of the current moment of the Java virtual machine. The thread snapshot is the method currently being executed by each […]

Tracing DNS query paths in Kubernetes

Follow the “Wonderful World of Linux” on the public account Set it as a “star” and let you play Linux every day! In past articles, we have traced network packets in Kubernetes [1], this article will trace DNS queries in Kubernetes. Let’s take the example of resolving the Service fully qualified domain name (FQDN) foo.bar.svc.cluster.local […]

01 | Tracing back to the past: How did TCP/IP and Linux change the world?

We are in an era that belongs to us, and we are enjoying the dividends of this era on the front line. In my opinion, there has never been a technology in human history that can affect every aspect of people’s lives as profoundly as the Internet. When it comes to Internet technology specifically, there […]

Frida prints the call stack of the function to facilitate tracing back the entire calling process of the function.

Using W3C Trace Context in a distributed tracing system

Use W3C Trace Context in distributed tracing systems https://dev.to/luizhlelis/using-w3c-trace-context-standard-in-distributed-tracing-3743 In software development, when a system encounters a runtime failure, developers will instinctively try to find where the failed method was called and where the original request was. This is what stack trace does, as shown in the example below. Unhandled exception. System.InvalidOperationException: Stack trace example […]

Memory Access Tracing

Memory Access Tracing refers to the monitoring and recording of all memory read and write operations during the execution of a program. It provides insight into how a program interacts with its memory, which is invaluable for various applications like performance optimization, security analysis is, and debugging . Key Concepts of Memory Access Tracing: Memory […]
