At last: RouteMap performs some analysis on your Signposts, and with the other tools can be used to estimate latency, and look at macOS system performance too.
Signposts
Picking the right time system for the purpose is critical when you want to analyse very short periods. Sometimes it takes time to discover how to juggle with time.
Doesn’t writing so much to the unified log result in performance penalties? So how can Apple expect us to use the log and Signposts to measure performance?
Blowhole 7 now writes proper Signposts in Mojave, as well as Pseudo-Signposts in Sierra and High Sierra.
At first I thought it was my mistake. Then it looked like a simple error in the interface. But this bug in Mojave’s signposts is more complex. Here’s a workaround.
A new version of Blowhole, the second alpha of RouteMap, and a complete tutorial toolkit to help you get started using log Signposts from Sierra to Mojave.
Do you want to measure performance or get other info from your app or script? Using Signposts is ideal, and here’s the first glimpse of a new tool to harvest them.
A detailed exploration of how to use Signposts to investigate performance of your code, and the limitations of Apple’s tools.
New tools for developers, scripters, and anyone who performs demanding tasks with their Mac(s).
If you’re running Mojave and using a scripting language which can’t itself access Signposts, Blowhole now gives you access to them.
