In this series of chaos engineering articles, let's discuss how to simulate CPU consumption to spike up to 100% on a host (or container). CPU consumption will spike up whenever a thread goes on an infinite loop. Here is a... Continue Reading →
Java applications tend to contain hundreds (sometimes thousands) of threads. The majority of these threads are in WAITING, TIMED_WAITING (i.e., dormant) state, while only a small portion of the threads are actively executing lines of code. So, we were curious... Continue Reading →

To troubleshoot a production problem, you might have to analyze multiple snapshots of thread dumps captured at periodic intervals. Each snapshot of thread tends to contain hundreds of threads, sometimes even thousands of threads. Each thread in the thread dump... Continue Reading →
Thread dumps are vital artifacts to debug & troubleshoot production performance problems. Thread dump files tend to span for several hundreds of lines (sometimes a few thousands of lines). It is hard to conceive and assimilate all the information in... Continue Reading →
