jWatchdog delivers a simple watchdog to actively monitor your infrastructure and send you notifications in case something goes wrong. It is configured using a simple XML configuration file. This configuration file can be changed on-the-fly without a need to restart the watchdog. jWatchdog does not offer data collection itself. It assumes that you already collected the data on which you want to run jWatchdog. The de facto standard tool Collectd is recommended for data collection. jWatchdog assumes that you use the RRDTool collectd output plugin to store the collected data in RRD files, or use Graphite as a datasource.
It's still a company
Very nice, of course. But why? Charity? Remember that TrollTech is a company. Goal: making profit. They say it's the license...euch there _marketing_ says it's because of the license. The real reason? Not profitable enough. The primary market they want to address is the same as GTK does. Second is Windows. But this has never been a big success. Name me one "big" application that is using it, except the ones TrollTech did write. When writing commercial (= Windows) software one doesn't have time to lear a new API.
We've got two players here (linux platform):
1. GTK -> Gnome
2. QT -> KDE
Gnome is doing it better than KDE. Why? GTK is not as good as QT for programming (yes I tried both).
So it's probably the license that is the problem.
But not from the side of TrollTech itself as they claim, but from the side of the (potential) users of QT.
They just want to write free software using free tools to do so. Inspired by other companies who also killed a piece of the software market by giving it all away for free they want to be sure no other company will ever profit the "API"-market and do the same.
Killing yes. I always found that the race between MSIE and Netscape ended when Netscape did open it's source...first thing Microsoft did with MSIE was...nothing. Cause the browser market has been cleared out. They waited a long time before releasing other version of MSIE and concentrated on other things, like Office & Visual C++.
Anyway. I still prefer GTK. Sorry, 2 years too late for me.
