Qt-Maemo5 xymon desktop widget for Nokia N900
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Hello, all.
I wrote a desktop widget for the Nokia N900 that polls xymon server status on a configured interval and reports the status via color icon and notifications.
The source and installation instructions (via debian repository) are here:

Hope someone finds it useful.
Feedback and criticism are always welcome. :)
Cheers, Darrik

The source and installation instructions (via debian repository) are here:
I have been using an N900 for a few weeks, but only just installed the SDK over the past weekend. So, I decided to grab the source and compile. When compiling from Qt Creator from the SDK install, it compiles fine, but package creation fails (possibly due to the directory name). After messing with some things to fix it, only the executable ended up in the package.
I'll see if I can find the correct fixes to get it to build nicely straight from Qt Creator.
Hope someone finds it useful.
Well, I wonder if we could make it more useful. From reading the code, it seems to just look at the color of the bb2.html page. While this may be useful to some, I think many larger installations will have problems, e.g. those which need the critical systems view to make sense anything.
So, the question is, should we provide data in different formats than HTML, for smarter clients (and not just mobile ones). For example, would XML output (such as that generated by the hobbitdxboard command in bb)? The client may want to specify the options to the hobbitdxboard command (e.g. configured from the widget).
I'll try and get a bit further with this under Qt creator ...

I caution you, it was five days' effort, so rough edges are just that still. Also, mostly the code is set up for my dev environment, to generate a debian package. If you have ideas for restructuring to make that more generic, don't hold back.
It should be noted that this was my first N900 project, as I just got one, and also my first shot at generating debian packages, so any advice is appreciated.

Let me know how that goes. I build from the command-line, so I'm not sure what would be going wrong in Qt Creator.

This is true. All it does is parse for color to display the icon, and then parses for individual non-green items to show in a notification. Multiple views (one for small- to moderate-sized xymon installs and one for larger) might be appropriate, selectable from the settings, perhaps.
This was not meant to be a full-scale app but just an at-a-glance view. If you're interested, we can always write a full-scale app that opens when the desktop widget is tapped, providing more (and navigable) data.
I'll try and get a bit further with this under Qt creator ...
If there's something specific I can help with, feel free to contact me off-list.

First of all, many thanks for this. I'm learning C and one of my first projects was to do something similar. On the suggestions side, I think it should be usefull to save SSL certificate from https servers. I use apache' http authentication. I'm quite paranoid ;) To hide password, at least in settings menu, should be very nice too. It should be nice to let user choose how long the alert status page is shown. Finally I installed your widget from your apt repo, configured everything (the username/pwd fields are for http auth ?) and it works pretty well.

Glad to hear you find it useful! Hiding passwords in the text input is something I realized but haven't gotten to yet. As for saving the SSL certs and comparing them, that's a good idea I hadn't thought of. It does use the SSL cert for establishing an encrypted connection (so your http basic auth isn't sent in the clear) but doesn't verify the cert in any way, mostly because everyone I know (including me) uses a self-signed cert.
Regarding the notification timing, you have two options. Manual (tap to dismiss) and the default N900 notification timeout, which I believe is 5 seconds.
If you feel like implementing any improvements, feel free to do so. You can fork the project on github, then give me a pull request when you're ready, or just send me a patch. If you're just learning c/c++, feel free to shoot me any questions about the code off-list (email or jabber: darrik at jabber.darmasoft.net). It's pretty straight-forward, but I'd be glad to offer any assistance I can. The world can always use more c programmers. ;)

Hi,
I've a strange behaviour since I installed your widget. When my device powers on, it asks me 2 times to connect. The first time I choose my connection (working), but the widget seems to ask a 2nd time anyway.

The widget makes no calls into the connection API. It simply requests a url from the connection access manager. It's entirely possible that the widget is create the connection access manager object prior to the connection being established, and so the NAM instigates the second request. Perhaps a delay on startup of xymon-widget would fix this issue. An improved version of xymon-widget would do a little connection checking and maybe offer a "wifi only" option as well. However, I didn't want to add the dependency on the qt-mobility library, as it seemed unnecessary and additionally seemed to be under rapid development with frequent API changes.
I'll try to isolate that behavior and see if a startup delay represents a suitable workaround for now.
As always, thanks for the feedback.
