[30p] Vmstat The vmstat utility provides a good low-overhead view of system performance. Since vmstat is such a low-overhead tool, it is practical to have it running even on heavily loaded servers when it is needed to monitor the system’s health. text/html 2025-03-17T20:59:08+03:00 http://ocw.cs.pub.ro/courses/ep/labs/03/contents/tasks/ex2?rev=1742237948&do=diff 02. [30p] Mpstat [10p] Task A - Python recursion depth Try to run the script while passing 1000 as a command line argument. Why does it crash? Luckily, python allows you to both retrieve the current recursion limit and set a new value for it. Increase the recursion limit so that the process will never crash, regardless of input (assume that it still has a reasonable upper bound). text/html 2026-03-16T19:48:43+03:00 http://ocw.cs.pub.ro/courses/ep/labs/03/contents/tasks/ex3?rev=1773683323&do=diff 03. [20p] Zip with compression levels The zip command is used for compression and file packaging under Linux/Unix operating system. It provides 10 levels of compression, where: * level 0 : provides no compression, only packaging * level 6 : used as default compression level * level 9 : provides maximum compression text/html 2026-03-16T19:48:53+03:00 http://ocw.cs.pub.ro/courses/ep/labs/03/contents/tasks/ex4?rev=1773683333&do=diff 04. [20p] Hardware Counters A significant portion of the system statistics that can be generated involve hardware counters. As the name implies, these are special registers that count the number of occurrences of specific events in the CPU. These counters are implemented through Model Specific Registers (MSR), control registers used by developers for debugging, tracing, monitoring, etc. Since these registers may be subject to changes from one iteration of a microarchitecture to the next, we wil… text/html 2026-03-16T16:52:49+03:00 http://ocw.cs.pub.ro/courses/ep/labs/03/contents/tasks/ex5?rev=1773672769&do=diff 05.
