Menu Meters is not officially compatible with El Capitan. Here's a source for an unofficial version. – IconDaemon Apr 12 at 20:17

MenuMeters is popular among the Mac users I know.

Thank you! That is exact what I need – Anonymous Mar 12 '11 at 10:14
    
Since I may come across people here who may have used MenuMeters, I would like to ask whether it is stable in terms of memory leaks and crashes. – ayaz Mar 13 '11 at 5:28

Doesn't work with El Capitan. – Restuta Oct 16 '15 at 20:19

It's free and open source and there's a fork that DOES work with El Capitan, @Restuta – Matthew Elvey Nov 16 '15 at 8:11

The fork for El Capitan is here member.ipmu.jp/yuji.tachikawa/MenuMetersElCapitan – user454322 Mar 7 at 5:01

iStat Menus is an app by Mac / iOS developers Bjango, but it's not free ($16).

For OS X 10.11 or later, use this fork of MenuMeters: http://member.ipmu.jp/yuji.tachikawa/MenuMetersElCapitan/

I also have the same needs but many such softwares are not free, thus I made one myself. Feedback is welcome.

I recommend SystemPal which is available on Mac App Store.

The iPulse program has been doing this since 2002.

It is recently updated for the Mac App Store and El Capitan and also works on older OS.

It's menu centric, dock centric and/or HUD style visualizations so you can choose exactly what and how you monitor the system performance.
