Manuia Memory Monitor

Hi!

Between two latexing session, I did a 3 hours long coding session. I produced Manuia, a real-time memory monitor. I attached a screenshot to this email.
You can try it by:

Gofer new
squeaksource: 'MetacelloRepository';
package: 'ConfigurationOfSpy';
load.
(Smalltalk at: #ConfigurationOfSpy) perform: #loadDefault

If you use a Pharo 1.1 then world menu/tools/Manuia Memory Monitor . Else, evaluate "ManuiaMonitor new open"
Green curve is about the memory consumption: when it goes up, when you consuming memory. Vertical bars indicate that at least 10 incremental garbage collect was realized.

There is a probe class button. Click on it, enter the name of a class, then you can see the evolution of the number of instances.

It is just a small experiment I did. I haven't got the time to intensively use it. Feedbacks are very welcome.

Cheers,
Alexandre

Re: Manuia Memory Monitor

Hi Alexandre. This is very interesting for me.

I just test it a little. I am quite intrigued to know if the attached screenshots are normal.

I just did nothing. I mean NOTHING in the image, while Manuia was running. I just left the mouse and keyboard doing nothing.

First was picture 11 and then 13.

Another question: what is the red curve in your screenshot? I don't have it.

Thanks

Mariano

Re: Manuia Memory Monitor

Alexandre: Is there a way (or will be in a future) a way to script and customize it ?

Suppose I want to trace several things, not only the amount of memory used. I would love to be able to define my own curves and have several at the same time.

Maybe what I need is just that graph but totally customized for me. Any hints?

Thanks in advance,

Mariano

Works just fine not loading the entire Spy/Mondrian packages as well...

Personally I'd really like to see something like this, combined with some of the textual data from Debug -> VM Statistics + Space left as a core tool. :)

Cheers,
Henry

Look at the code, it's quite simple. :)
All you seem to have to do is subclass MMProbe, implement its interface (get current value, choosing a color, and potential custom rendering) and voila, you have a custom curve!

And of course, when looking a bit closer, it's even simpler :) (If you don't need custom display etc. that is)

graph := MMGraph new.
probe := MMProbe probleBlock: [:theProbe | theProbe addValue: someValueIWantACustomGraphFor].
graph addProbe: probe; openInWorld.

not sure if probleBlock is a spelingError :)

Cheers,
Henry

PS. Would it be possible to do:
ManuiaMonitor>> initialize
graph := MMGraph new.
graph addProbe: MUsedMemoryProbe new; addProbe: MMGCProbe new.

(and only window addMorph: graph in the open method)

and remove

self addProbe: MUsedMemoryProbe ... from MMGraph initialize?

That way, a graph not used by the monitor is empty by default, and a new instance can be used for whatever graphing purpose one desires, like Mariano :)

Yep.

Gofer new
squeaksource: 'MemoryMonitor';
package: 'ConfigurationOfMemoryMonitor';
load.
((Smalltalk at: #ConfigurationOfMemoryMonitor) project perform: #lastVersion) load.

It just loads 6 small classes. Accessible under the "World/Tools/Memory Monitor" menu item.

Cheers,
Alexandre

Making and keeping it simple is a strong requirement :-)

It is, indeed.

Nicer yes.

New version in the SqueakSource MemoryMonitor repository

Alexandre
