What tools are available to record/log Linux activity at the process level? Scenario: 1. LinuxA normally uses a steady ~30% cpu. 2. At 10:30am, it was noticed that LinuxA's cpu pegged 100% and memory consumption increased to the point of heavy swapping 3. At 11:10am, LinuxA's cpu went back to ~30% and memory utilization returned to normal. 4. It is now 3:00pm. How can I go back in time to find the culprit application/process for the 40 minutes of hiatus? In zVM, I have the performance toolkit and MONWRITE data. In zOS, I have RMF. Does Linux have a comparable tool? Thanks, Kevin
