RPi-MonitorWatcher - Android App

[Tido]

Hi,

 

This is new to me and probably to you too.

If you look a little bit around in this Forum you will find that RPi-Monitor is a well known tool and can be adjusted to your SoC.

 

Now I found this project on Github

RPi-MonitorWatcher

Raspberry Pi Monitor Watcher is an Android application to view the status of your Raspberry Pis. It uses the API provided by Raspberry Pi Monitor.

 

Someone might now think "my mobile has a browser"  what do I need this for. Because you can

I cannot find an .apk if you are smarter than me and know what I have to do to get this I would be grateful.

 

Cheers

Install Android SDK and Android Studio with its dependencies and try to compile this project?

Thank you Zador - I did not think about that   my lack of having no programming know how.

I will write to this guy and ask him for an .apk he is swiss too. I hope a kind one :-)

An alternative would be to think about the whole approach first and then drop the whole idea.

 

RPi-Monitor if adjusted to the data sources of the boards we play here with is a great tool to explore system behaviour (as part of a development/optimization process) since it's leightweight enough to not tamper the system's behaviour it should monitor.

 

When you have a look what RPi-MonitorWatcher is doing then it's just plain 'fooling yourself' as usual: https://github.com/tobiasfiechter/RPi-MonitorWatcher/blob/master/app/src/main/java/io/hotkey/rpi_monitorwatcher/model/Raspberry.java#L16-L22

 

Numbers without meaning displayed in nice colors. And the usual misunderstanding of 'average load' which is most of the times NOT CPU related on Linux SBCs (the author calls average load 'statusCPULoad' which is plain wrong). To understand what's wrong with such approaches please see http://forum.armbian.com/index.php/topic/1160-login-script-enhancement-for-load-average-color/?view=getlastpost

 

But I doubt that this information will help since most people love numbers without meaning especially when nice colored graphs have been made of them.

I second @tkaiser. Average load is entirely CPU related in any moderated loaded Linux server, not only Linux SBCs. Better cross that data with `vmstat` output.

Often besides having the tools at hand, it is advised to know how to look at the data.

 

While extremely biased over dtrace, I recommend this book "Systems Performance: Enterprise and the Cloud", http://www.brendangregg.com/sysperfbook.html for anyone interested in delving on the subject.
