Post date: February 13, 2007, 18:02 Category: Network Views: 4025 Comments
Tutorial quote: Munin” means “memory”.Munin the tool surveys all your computers and remembers what it saw. It presents all the
information in in graphs through a web interface. Its mphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily
monitor the performance of your computers, networks, SANs, and quite possibly applications as well. It makes it easy to determine “what’s different today” when a performance problem crops up. It makes it easy to see how you’re doing
capacity wise on all limited resources.

X Window Manager Benchmarks (E17 on Top)

Post date: June 9, 2005, 14:06 Category: Benchmarks Views: 3811 Comments
Tutorial quote: I've been focusing on some stability issues of late in E17, but more importantly - speed. I've been doing a little profiling and shaving off cycles where I can find readily optimizable code. I have E17 starting in 0.52 seconds (from execute to usable desktop). Considering that involves loading and rendering and scaling a complex multi-leayered desktop background, loading multiple useful modules (pager, ibar, start, dropshadow, cpufreq handler, clock, etc.), then that's not too bad.

Now I'm a numbers man. I like numbers. I don't like vague "it's faster than X" or "that's slower than this" statements without numbers to back it up. I also like to play fair. Also given there are no "performance suites" i know of that measure window manager performance, I wrote a quick and dirty one.

CGI Programming on the World Wide Web

Post date: December 12, 2005, 17:12 Category: Programming Views: 3044 Comments
Tutorial quote: The Common Gateway Interface (CGI) emerged as the first way to present dynamically generated information on the World Wide Web. CGI allows the computer to generate Web pages instantly at the user's request rather than being written by someone in advance. And at the time of this writing, it remains the only stable and well-understood method for creating such pages. Java presents problems that have not yet been solved. Other products are currently just in the announcement stage.

CGI is fun. You can get a kick out of writing scripts that perform tricks for you, and the users enjoy the spice the scripts add to your Web pages. But CGI has a serious side too: It lets the Internet offer the kind of interactive, user-driven applications that modern computer users have come to expect. CGI opens up an entire class of modern applications to the Web.

Monitoring Servers and Clients using Munin

Post date: April 4, 2006, 20:04 Category: Installing Views: 2533 Comments
Tutorial quote: "Munin" means "memory".

Munin the tool surveys all your computers and remembers what it saw. It presents all the information in in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, and quite possibly applications as well. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity wise on all limited resources.

It uses the excellent RRDTool and is written in Perl. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for sdata. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).
