You can check whether large backups or downloads are taking place in the Network tab. If you have Dropbox or Spotify installed, it's worth checking whether they are using too much network bandwidth, for example. Use the Search bar to check on a specific program or process. To force quit an item, click it in Activity Monitor's list, then on the X at the left of the toolbar, then confirm you want to force quit it. This is usually accompanied by unresponsive behaviour from the app in question (although some processes run behind the scenes). When a process is shown in red, this is Activity Monitor's way of saying it's unresponsive. If Safari shows a web-based game or video clip using a significant portion of the CPU even after you've stopped using it, it's likely to have stalled.
PROCESS MONITOR MAC HOW TO
In the next performance monitoring post we’ll dive deeper into how to chart and make sense of the data we have collected in this post.It's perfectly normal for these to occur as you open an app, download a video or render a complex, layered image. index="your_index_here" sourcetype=generic_single_line Once all the data is broken out into fields you can easily chart CPU and energy impact broken out by individual processes.
PROCESS MONITOR MAC PORTABLE
This regex should be portable to other log analysis tools if they conform to the PCRE regex standard but I have only tested this on Splunk.

Splunk regex for parsing powermetrics logs Here is the LaunchDaemon plist that I have been using to collect this information in the background on my test machines. This will give you relative performance statistics to help determine the qualitative “feel” and “slowness” an application may be causing.

Compare native processes like WindowServer, Safari, and Mail to the target application.A simple example would be: “reboot, immediately run target application, perform X task in target application, stop log collection” Create a repeatable testing plan so you can change variables and maintain data integrity.

Use some analysis tool like Splunk, Kibana, or event Excel instead of trying to read the logs manually.If the application you are testing uses a kernel extension be sure to chart kernel_task with that KEXT loaded and without that KEXT loaded.We have since moved to more advanced ways to collect energy impact and performance telemetry for cmdReporter’s internal testing, but I have run the above command as a LaunchDaemon on my own machine for months at a time without noticing any additional overhead. # -u /tmp/powermetrics.log Output to file location # -show-process-energy Show energy impact scores # -show-process-io Add disk i/o and pageins to results # -s tasks Focus on per-process information # -a 0 Don't display summary line, not useful in this case usr/bin/powermetrics -a 0 -i 15000 -s tasks -show-process-io -show-process-energy -u /tmp/powermetrics.log Here is the terminal command that will collect statistics for all processes running on your machine every 15 seconds and write the output to a file in the /tmp/ directory. How do I collect energy impact information via the command line? True to its name, energy impact seems to be a decent measure of the impact an app or process has on the computer both in “feel” and in battery usage rates. The additional research I have done says that energy impact is calculated on CPU %, CPU power draw, GPU usage, whether or not an app has any power assertions (pmset -g assertions) to keep the computer or screen active, memory usage, and network usage.

Per Apple’s public documentation here energy impact is:Įnergy Impact: A relative measure of the current energy consumption of the app. What does the energy impact score mean and how is it calculated?
PROCESS MONITOR MAC MAC
This command collects a lot of information about each process running on your mac but the most important metric will be the “energy impact” score macOS gives to each process. Luckily Apple has provided a handy tool called powermetrics to help get some baseline statistics about just how much a process or group of processes are affecting the performance of your mac. How can you even track CPU usage over time without sitting there with Activity Monitor or Console.app open all day? Performance monitoring can be tricky, does constant, but lower CPU usage slow down a mac more than intermittent high CPU usage? Do either of those affect the battery life more than the “feel” or speed of macOS?
