What is "signpost_reporter"?

Today I updated my 2014 MacBook Air to macOS Mojave 10.14.5 as it just released. After the update finished, I checked console logs and noticed in 'System Reports' there's a log named "signpost_reporter[date & details].cpu_resource". In the console log the path is /usr/libexec/signpost_reporter, a path i've never seen before until today. I also updated my family's iMac to 10.14.5 but no signpost_reporter log was created after the instillation finished. What exactly is "signpost_reporter"? What is it's function? Why did I get a log for it?
