name : loads_example.txt Demonstrations of loads, the Linux bpftrace/eBPF version. This is a simple tool that prints the system load averages, to three decimal places each (not that it really matters), as a demonstration of fetching kernel structures from bpftrace: # ./loads.bt Attaching 2 probes... Reading load averages...
