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... Hit Ctrl-C to end.
21:29:17 load averages: 2.091 2.048 1.947
21:29:18 load averages: 2.091 2.048 1.947
21:29:19 load averages: 2.091 2.048 1.947
21:29:20 load averages: 2.091 2.048 1.947
21:29:21 load averages: 2.164 2.064 1.953
21:29:22 load averages: 2.164 2.064 1.953
21:29:23 load averages: 2.164 2.064 1.953
^C

These are the same load averages printed by uptime:

# uptime
 21:29:24 up 2 days, 18:57,  3 users,  load average: 2.16, 2.06, 1.95
