Alfred 2 Top Process Workflow
The initial motive of this workflow is to avoid frequent visits to the Activity Monitor when the fan goes loud. Now it has been evolved with two major features:
- List/Kill Top Processes by Memory/CPU/IO Usage
- (working in progress) Get a glance of system status including internal battery, fan speed, CPU/GPU Temperature, bluetooth battery, disk capacity, etc.
0. Show Help
--help after the keyword to show help.
1. Top Processes
top: Show a mixed processes list based on top cpu/memory usage.
top --memory to show processes ranked by memory usage
top --cpu, to show processes ranked by cpu usage
top --io, to show processes ranked by io usage with callback from top io trace collector.
Top IO requires DTrace and it would take a while to finish. The new callback design is to run the job in he background and post a notification (OSX 10.8+) using notification center. Click on the notification to show the result in alfred.
none: The default action is to list files opened by process ID
control: Kill the selected process
command: kill forcefully (
alt: Nice (lower) the selected process's cpu priority
shift: Search web for process information
kill: Filter process to kill.
none: The default action is to kill by process ID
command: kill forcefully (
lsof: List files opened by process id
none: The default action is to reveal file in Finder
B. Filter by Query
1.) Type process name to filter
2.) To search for process state, use :idle, :sleep, :stopped, :zombie, :uninterruptible, :runnable, etc.
2. Glance an Eye on your system
glance: Show system information including internal battery, bluetooth battery, disk capacity, etc.
B. Change Display Order
Top Result Keyword Latching
Enterfor the feedback item you wish to show up on the top.
Two ways are provided:
You can download the Top Processes.alfredworkflow and import to Alfred 2. This method is suitable for regular users.
forkthis repository and use
rake uninstallto install. Check
rake -Tfor available tasks. This method create a symlink to the alfred workflow directory: "~/Library/Application Support/Alfred 2/Alfred.alfredpreferences/workflows". This method is suitable for developers.
1. Does not work in Mac OSX 10.9 (Maverick)
In OSX 10.9, the system ruby is upgraded to 2.0.0. You need to download the new version of this workflow which packs the ruby gems for 2.0.0 inside.
If the downloaded version does not work, try
Terminal.app. If you use rvm or rbenv, switch to the system ruby.
cd "$HOME/Library/Application Support/Alfred 2/Alfred.alfredpreferences/workflows/me.zhaowu.top" && rake bundle:update
2. iotop causes mouse lagging
This issue is not caused by this workflow but by DTrace. The related system log message is
IOHIDSystem cursor update overdue. Resending..
In my Macbook Pro, any DTrace based program will introduce this issue including the mac built-in
I upgrade to OS X 10.9 and this issue is resolved.
3. Encoding:(CompatibilityError) incompatible character encodings: ASCII-8BIT and UTF-8
Add the following contents to
/etc/launchd.conf. Restart is required.
setenv LANG en_US.UTF-8 setenv LC_ALL en_US.UTF-8
