I would like to see a powerful monitoring application, including database archiving of statistics. Coincidently, I wrote such software ;-).
Moodss is a modular monitoring application, which supports the Linux operating system (CPU, memory, disks, sensors, ...), databases (MySQL, ODBC, ...), networking (SNMP, Apache, ...), and any device or process for which a module can be developed (in a scripting or compiled language: Tcl, Python, Perl, C). A very intuitive GUI with full drag'n'drop support allows the construction of powerful dashboards with graphs, pie charts, ... Proactive monitoring is achieved via a thorough thresholds functionality, including warning by multiple emails, user defined scripts, and an included daemon for background monitoring. Finally, on top of real-time monitoring, any part of the visible data can be stored in a SQL database (MySQL or ODBC) by both the GUI and daemon applications, so that, for example, complete history over time can be made available in web pages, common spreadsheet software, or presentations.
If you manage a dynamic international web site, and you suspect overloading occurs during the night, you could record statistics on the system (CPU usage, memory, swapping, disk, ...), network (ethernet device, router ports via SNMP), database health and I/O, and load on the Apache web server, then browse the results in the morning using the same graphical software to determine the origin of the problem.
More information, reviews, ... can be found at http://jfontain.free.fr/moodss/ Should you like to try it, all the required software in the bugzilla QA pipe:
