In this post, we are going to discuss a non-intrusive approach (i.e., approach that doesn’t add any noticeable overhead to the application) to diagnose CPU spike. Thus, you can use this approach in your production environment to troubleshoot CPU spikes. Works on all JVM languages: This approach can be used to troubleshoot CPU spikes in... Continue Reading →
Due to the heat of the moment, most SRE engineers restart the application without capturing the right data to debug the problem. Without the right data, debugging the production problem can be hard. yCrash data script captures below mentioned 360-degree data that too at the right moment. These artifacts will be highly useful to troubleshoot... Continue Reading →
CPU consumption in Unix/Linux operating systems are studied using 8 different metrics: User CPU time, System CPU time, nice CPU time, Idle CPU time, Waiting CPU time, Hardware Interrupt CPU time, Software Interrupt CPU time, Stolen CPU time. In this article let us study about ‘waiting CPU time’. What is ‘waiting’ CPU time? Waiting CPU... Continue Reading →
