Add option to show CPU activity per-core

[Simone Bordet]

Ubuntu 13.04
indicator-multiload 0.3-0ubuntu1

A request for a new feature: it would be awesome if indicator-multiload could show the CPU activity also on a per-core graph.
The correspondent gnome shell extension can do that just via ticking a checkbox that "splits" the CPU graphs.

Thanks !

Hi Simone,

thanks for the bug report!

Do you have a screenshot what it should look like?

Best regards

Michael, see attached screenshot.

It shows the configuration dialog for the gnome-shell system monitor extension, which has a checkbox "Display Individual Cores".

When this is ticked, you can see that the CPU graphs in the panel (at top) are now one per core. In the screenshot you can see the 2 leftmost graphs (in blue) as my laptop has 2 cores, and you can see that the graph pattern is different between the 2 cores (so it's the real activity of each core, as System Monitor is also able to report).
After the 2 CPU graphs I have one graph for network (yellow) and one for the disk (red, just a couple of spikes).

I understand that having 8 graphs for 8-cores CPUs may take a lot of space, but people can tune the width of the CPU graph or opt to not display individual cores.

However, for people like me, having the individual core activity available with a glance at the top panel would be a nice feature.

Thanks !

What I really love to see is an overall graph for cpu and present values per core.
This is why I love this two applets for xfce: https://www.dropbox.com/s/87q1equnash2hns/scn1.png?dl=0
This is default look of them.

And this is after some customisations: https://www.dropbox.com/s/qhy59kbysoas5kv/scn3.png?dl=0
Four vertical bars show me if some app is limited by a speed of single core, it's useful to see. As you can see at next area I can't see this clearly from overall cpu load. Yes, it's 25%, and if I will not see core bars vith individual values - I will think that bottleneck is not in cpu-things.
Next is memory, swap, uptime, and network. Also I look for HDD I/O-meter which will show me current HDD transfer speed.

Agreed with denixx: an instantaneous (and space-preserving) bar graph per core, plus a combined graph of CPU load history (i.e. what we have now) would be the ideal approach to display all relevant information in a compact way.

Sorry, looks like I dropped those screenshots... I would make new ones, but it would not be fast. Sorry again, I made my message slightly blind.
