#! /usr/bin/python3 # @lint-avoid-python-3-compatibility-imports # # cpuunclaimed Sample CPU run queues and calculate unclaimed idle CPU. # For Linux, uses BCC, eBPF. # # This samples the length of the run queues and determine when there are idle # CPUs, yet queued threads waiting their turn. Report the amount of idle # (yet unclaimed by waiting threads) CPU as a system-wide percentage. # # This situation can happen for a number of reasons: # # - An application has been bound to some, but not all, CPUs, and has runnable # threads that cannot migrate to other CPUs due to this configuration. # - CPU affinity: an optimization that leaves threads on CPUs where the CPU # caches are warm, even if this means short periods of waiting while other # CPUs are idle. The wait period is tunale (see sysctl, kernel.sched*). # - Scheduler bugs. # # An unclaimed idle of < 1% is likely to be CPU affinity, and not usually a # cause for concern. By leaving the CPU idle, overall throughput of the system # may be improved. This tool is best for identifying larger issues, > 2%, due # to the coarseness of its 99 Hertz samples. # # This is an experimental tool that currently works by use of sampling to # keep overheads low. Tool assumptions: # # - CPU samples consistently fire around the same offset. There will sometimes # be a lag as a sample is delayed by higher-priority interrupts, but it is # assumed the subsequent samples will catch up to the expected offsets (as # is seen in practice). You can use -J to inspect sample offsets. Some # systems can power down CPUs when idle, and when they wake up again they # may begin firing at a skewed offset: this tool will detect the skew, print # an error, and exit. # - All CPUs are online (see ncpu). # # If this identifies unclaimed CPU, you can double check it by dumping raw # samples (-j), as well as using other tracing tools to instrument scheduler # events (although this latter approach has much higher overhead). # # This tool passes all sampled events to user space for post processing. # I originally wrote this to do the calculations entirerly in kernel context, # and only pass a summary. That involves a number of challenges, and the # overhead savings may not outweigh the caveats. You can see my WIP here: # https://gist.github.com/brendangregg/731cf2ce54bf1f9a19d4ccd397625ad9 # # USAGE: cpuunclaimed [-h] [-j] [-J] [-T] [interval] [count] # # If you see "Lost 1881 samples" warnings, try increasing wakeup_hz. # # REQUIRES: Linux 4.9+ (BPF_PROG_TYPE_PERF_EVENT support).
