How do I create Cacti Graph Templates? How do I display multiple data sources on one Cacti graph? What do all the Cacti options mean? What is a CDEF? I created a Cacti Graph but all of my data sources are displaying NAN, how do I troubleshoot that?

Cacti is a powerful RRDTool based graphing system typically used for graphing hardware and software data for historical reference. When I initially configured a Cacti Graph Template I found some of the options confusing but as you will see below they all make sense and typically the name explains each items function in a fairly easy way. Please post a comment if you have any further questions that are not answered or if I have made any answers feel free to use the contact form and point them out to me as I am trying to learn the best way to use Cacti just like everyone else. I repeat the same terms many times in this document simply for the fact to try and explain in detail what things mean. I did not want to start switching names with acronyms and vice verse to add confusion and to try and make this a very easy document to understand.

Technology Errors

iTunes was Unable to Load Provider Data from Sync Services

If you are unable to sync your iPod don’t try restoring or anything just yet as the problem might be extremelly simple to fix. I noticed that on my Windows XP laptop that if I plug my iPod into different USB ports that things act differently. I have three USB ports on the back of my Dell d420 laptop and I installed my iPod Touch while using the port in the back all the way to the left. Everything works fine if I sync using this port however if I try using one of the other two USB ports on the back of my laptop I get the following errors.

The first pop up error states the following:
iTunes cannot sync information with the iPod “iPod Name” because syncing has been disabled on this computer. Do you want to enable syncing?
If you do not enable syncing, iTunes will not be able to sync contacts, calendars, bookmarks, or mail accounts to your iPod.

How to Blur a Portion of an Image with Photoshop

Blurring portions of an image with Photoshop is a snap. The most complicated part is figuring out which blur effect you want to use! There are a ton of choices including Blur, Blur More, Box Blur, Gaussian Blur, Lens Blur, Motion Blur, Radial Blur, Shape Blur, Smart Blur, and Surface Blur. My personal favorite for blurring parts of an image is Lens Blur but all of them allow for adjustment as well so you can make the blurring effect more intense or less intense. Click more for images of how to blur a section of your image with Photoshop CS2.
