[Announce] BatteryGraph
 
1 Attachment(s)
I wrote a program BatteryGraph for monitoring battery status on a Nokia N900.

BatteryGraph will monitor the battery statistics and shows the results in a graph. Also monitors average cpu load and network connection.

It's available for download from http://maemo.jeroenwitteman.com/BatteryGraph/
(I'm trying to get it in the maemo extras repository)
EDIT: it is now available in Extras-testing and Extras.

As this is the first release the usual warnings apply, installing this program may harm your device in many ways (though it is running fine on my N900 :) )

very cool , will be incredibly useful, not sure if this much but if you could capture the 'top' information at that time in the log's or a way of seeing when certain process's where started. It would be cool to see the 30% battery drop in a time period was also in the period you started media player for example.

Re: [Announce] BatteryGraph
 
Released a new version today with some updates.
Download from http://maemo.jeroenwitteman.com/BatteryGraph/ (for now)

I have uploaded it to extras-devel, but I'm not listed as the package maintainer (still pending :confused:) so I cannot promote it to testing.
Anyone knows how to fix that? See http://maemo.org/packages/view/batterygraph/

Changelog 0.2.2-1
  • Added option to move forwards/backwards in time by clicking on the right/left side of the graph (clicking in the center will toggle fullscreen)
  • Added minimum and maximum value for voltage and current in the graph
  • Added database statistics

What's the difference between this and battery eye? Which is better?

ndi 2010-02-21 21:12
Re: [Announce] BatteryGraph
 
Didn't get battery graph, but i use battery-eye and it's very nice, better graph, one graph per detail (voltage, percent, mAh estimate), eats zero battery and the graph can be swooped back about a week or so ago. Kinetic scrolled and everything. Zero issues.

BatteryGraph version 0.2.2-1 is now in Extras-testing. You can vote for it here.

I was going to suggest that there used to be a similarly named app for Palm OS a long time ago. But it seems that it's made by you also.

I am currently developing quite similar app called battery-eye, and I must admit that it is inspired by a vague memory that I used to have something similar on my Palm m500 several years ago... ;)

I'm also using battery-eye. It runs without problems and is pretty nice.

BatteryGraph for PalmOS is indeed also made by me (and is still available)
I have been using my Sony Clie TH-55 until I got my N900 and still use some Palm apps (still no good alternative for DateBk5) with Garnet VM on the N900.

Hey, not clear how to get GarnetVM on the N900. I didn't see it in the repositories. Do you go to that site and install the OS2008 version?

Yes, there's no Maemo5 version but the OS2008 seems to be working fine.

No - it takes up about 3M of rootfs space. I optified it manually:
Code:
sudo gainroot
mv /usr/bin/gvm /opt
ln -s /opt/gvm /usr/bin/gvm

Re: [Announce] BatteryGraph
 
Great work! :)

Some small bugs, but it seems okay. Keep going! :)

Oh, and please. The text for the current seems to be to darkly tinted. It's hard to read on the black background. Could it be a good idea to have here a light blue?

Or perhaps more technical colors... during my studies Voltage was ever blue, Current ever red. You could use green for the percentage.
But, thats only colors... not so important. :rolleyes:

Re: [Announce] BatteryGraph
 
Hi, I guess that the graphs are done reading some data files. I would like to ask in which directory the data files are written and if the old ones can be deleted, and, eventually, if they are to be deleted by hand or if it is performed automatically.

jwittema 2010-03-09 09:39
Re: [Announce] BatteryGraph
 
Data is stored in a sqlite database which is located in the file /home/user/.BatteryGraph/BatteryGraphDB.sqlite

Currently the database is not cleaned automatically. In the next version of BatteryGraph you will be able to limit the maximum age of records in the database.

Can you delete a file and start the db over again?

Re: [Announce] BatteryGraph
 
Wow, locks great! :)

I installed it a couple of minutes ago. So far so good. Seems to work fine.

I've got just one small Problem:
1. go to the Options menu
2. tab on the "Database age limit" Dropdown Menu

Expected outcom:
the before selected Option should be selected as default

Actual outcom:
always the first Option is selected

The same problem with the "Scrollback history".

But everyting else works just fine! :) I think I will vote soon.

R.Habrat 2010-03-17 21:26
Re: [Announce] BatteryGraph
 
Thanks for developing that!

I would like to ask for a small enhancement:
It would be nice to have the possibility of turning off the graph lines for Percent and Volts during the charge period (instead of leaving them at last value level and then making them jump at the end of charging).

Hmm, weird. I can only reproduce this for "Database age limit".
For scrollback history the correct option is always highlighted on my device.

The weird thing is, when you scroll down the options dialog a little bit (still leaving the option "Database age limit" in view) it works like it should for "Database age limit".

Looks like a Qt bug to me :confused:

In version 0.3.0 this has already changed because the background daemon no longer polls the battery status on a regular interval. Instead it receives a dbus event when the values change resulting in a diagonal line for percentage and voltage during charge.

R.Habrat 2010-03-20 18:11
Re: [Announce] BatteryGraph
 
I see it works way better than with pure diagonal: if the device is used during charging, the voltage goes up with real values - surely there are many dbus events. It's easy to see it with zoom 0.5. The diagonal is used only when the device is idle.

Re: [Announce] BatteryGraph
 
BatteryGraph version 0.3.1 can now be found in Extras-Testing

Changelog
  • Added option to export entire graph to png image file

The entire graph will be saved as a (very wide) png image in /home/user/MyDocs/.images/BatteryGraph

Too bad you can't attach images this wide on this forum :(
Look here for an example image.

Re: [Announce] BatteryGraph
 
Using 0.3.1.

I must say, you have done a great job.

I have an issue with switching the graph to dispaly in full or partial screen mode.
The problem is that when sliding the graph left & right it will sometimes switch between these modes (full / partial) all by itself.
And every time it switches modes I have to scroll from the beginning to find the interesting spot.

So this is 2 problems:
1) accidental switching.
2) after switching - graph is reset to beggining.

Re: [Announce] BatteryGraph
 
One tiny request:
Could you *not* draw the Charger status on the graph? It appears to be a binary value anyway, so it is sufficient to show it by marking time axis in green.

Re: [Announce] BatteryGraph
 
hey :)
cool looking app, do I need to keep it open/running to monitor the battery, or is it performed by a daemon in the background?

There is a daemon in the background. :)

I was annoyed by this too :). So this behavior will be changed in next release. It will require a double click to toggle fullscreen mode and there will also be a menu option to toggle fullscreen (for those who can't doubleclick :) )

This will be configurable in next release.

Thank you for your suggestions.

Was about to comment on this, good to know you are aware :)

A few possible suggestions:

- Add a legend for colors in the exported image, as it is now i wouldnt know if a user set a color for something i cannot see (not too important)

- Add a background color selection (could be easier to adjust colors for the colorblind like me lol), and also allow for adjusting transparency values (if possible, it would be nice to have a transparent wifi/grps such that colors dont interfere with each other)

- Allow for splitting the exported graph into chunks (as a programmer i realize that to make this really versatile, you would have to define a start time and a period for each of the chunks but it would primarily be helpful to compare day-by-day battery consumption so a fixed daily period would do wonders for a start ;)

Thanks very much for the great program :)

Three suggestions: network traffic, call duration and cell signal strength
 
I have three suggestions:

- Logging network traffic on either interface (GPRS/3G and WLAN, i.e. two graphs: one for 3G/GPRS and one for WLAN, both combining RX and TX bytes)
- Logging call duration
- Logging cell signal strength

I posted them with somewhat more info here:
https://garage.maemo.org/tracker/ind...1351&atid=5007

As to how to represent them in the graph... cell signal strength is obvious, a line. Call duration and network traffic is somewhat similar, could be a line or bar to show bytes/minutes per interval/period (fixed/user configured/dynamic according to zoom level), or (esp. for call duration) it could be a line showing accumulated call time since the previous (full) charge, as this is a value commonly advertised.
