Bahkan Obama gunakan FusionCharts..

We Dissect Twitter’s Visualization of President Obama’s #SOTU2014 Talk

The President’s State of the Union address generates a lot of tweets and is a great candidate for visualization. That’s just what Twitter did this year in their #SOTU2014 visualization. In this post, we take a look at what the visualization gets right, and what it could have done better.
Edward Tufte, a data visualization expert, says that the goal of a visualization is to give the viewer ‘the greatest number of ideas in the shortest time with the least ink in the smallest space.’ The President’s talk itself lasted for a little over an hour. However, you can get an overview of the entire talk in under a minute using this streamgraph:
The streamgraph beautifully shows the ebb and flow of each topic during the talk. Now, another chart type like the stacked area chart could have done the job, but it wouldn’t have worked as well. The streamgraph here shows the fluid form of the talk, and is the ideal chart to be used here.
Selecting any section within it simultaneously updates the text area, map, and bar chart. This makes for an interactive, and data-driven experience. More importantly, it lures the viewer into exploring the finer details.
This visualization particularly stands out for its clever use of color. Notice how it grays out the time units along the axis, and uses color to draw focus to the main chart area, where the data actually is. This is in line with Tufte’s famous ‘Chartjunk‘ principle.
Map and Bar Chart
The streamgraph, map, and bar chart maintain unity in their use of color. It’s fascinating to scroll across the streamgraph and watch the topics change accordingly in the map. The map doesn’t show multiple categories simultaneously, which can be confusing. Instead, it shows just one category at a time, and varies the intensity of the color by state. This is the recommended way to use color on a map. There is a legend for the map, but with the exceptional use of color here, the map can be understood just as well without it.
There is unity not just in the use of color, but even in interactivity. When scrolling through the text one paragraph gets highlighted at a time. Along with it, the map, and bar chart are automatically updated. This keeps everything in context, and invites the viewer to not just read, but analyze the talk.
Now, while this visualization does a lot of things right, there are a couple of things we think it can do better. First, the bar chart seems pointless. It shows the same data as the timeline chart on top, and doesn’t do a better job of it. Yes, it’s slightly more accurate, showing exact differences in volume of tweets, but we wonder if that’s enough to justify its need. Instead, this space could have been used to show more granular information like a wordcloud of the tweets. It would have taken some more data crunching, but hey, it’s Twitter we’re talking about here, they have one of the best data systems in the world.
Tooltip of Map
Next, mousing over the map or the streamgraph shows a tooltip. In both charts, the tooltip adds very little new information. In case of the streamgraph, it orders each topic by volume of tweets, which we could already see better without the tooltip. In the map it shows something like ‘High engagement in California’ for example, which again we could see from the map itself. Instead, the tooltips could have been used to drill down to the approximate number of tweets from that region. This would have put focus on the data itself.
To conclude, this visualization is interesting because of the importance of the data it represents – the State of the Union address. However, it excels because of its choice of chart types, the unity between the different parts of the visual, and the careful use of color. It’s a another great example of how to visualize big data.
P.S. – Oh, and while we’re talking about the President, did you know he uses FusionCharts!
Barack Obama uses FusionCharts

Monitoring Jaringan Cisco dengan PRTG

As a network administrator, you know about the power and importance of Cisco devices. Whether you use Cisco routers, switches, access points, or VoIP (Voice over IP) solutions within your network-PRTG Network Monitor provides the exactly right sensor that will deliver the data you need to keep your network running smoothly.
Being a member of the Cisco Developer Network, we not only have long-term experience with Cisco, but also in gathering important information from these devices and placing them at your disposal.
Besides offering several sensors that you can use with Cisco systems (for example, NetFlow sensors), PRTG offers 6 dedicated sensors for Cisco application scenarios:

1. Cisco IP SLA Sensor

IP SLA (IP Service Level Agreement) is part of the Cisco IOS Software. It uses active traffic-monitoring technology to monitor continuous traffic on the network, thus being a reliable method in measuring overhead network performance. Our Cisco IP SLA sensor enables you to monitor relevant network parameters of important IP applications and IP services, like for example VoIP, through IP SLA results from Cisco devices via SNMP (Simple Network Management Protocol).
Regarding IP SLA, PRTG supports the following operations:
  • echo
  • pathEcho
  • fileIO
  • script
  • udpEcho
  • tcpConnect
  • http
  • dns
  • jitter
  • dlsw
  • dhcp
  • ftp
  • path-jitter
With the dns operation, for example, you can measure the DNS (Domain Name System) response time which is computed by calculating the difference between the time taken to send a DNS request and the time a reply is received. For VoIP, especially the jitter operation is important because it measures the variance in inter-packet delays between the source and the destination, as well as the other way around. For an IP service, such as VoIP which is extremely sensitive to inter-packet delay and packet loss, this operation is definitely one to remember.
The IP SLA sensor will provide you with live values for the following parameters, so you see all relevant information about QoS (Quality of Service) in your network:
  • Average RTT (Round-Trip Time)
  • Average Jitter (Destination - Source/Source - Destination)
  • Average Latency (Destination - Source/Source - Destination)
  • Downtime
  • ICPIF (Calculated Planning Impairment Factor)
  • Late Packets
  • Maximum/Minimum Latency (Destination - Source/Source - Destination)
  • Maximum/Minimum RTT
  • MOS (Mean Opinion Score)
  • Packets Lost
  • Packets Out Of Sequence
  • Transaction RTT
ICPIF, for example, represents predefined combinations of packet loss and packet delay in a VoIP network call and is a standard for measuring QoS. Another important parameter is MOS, which also is a well-established metric to obtain the quality of VoIP. By providing a numerical indication of the perceived quality of received media after compression and/or transmission, it gives you an overall benchmark for QoS in your network. When using the MOS channel in the IP SLA sensor, PRTG directly monitors this value on the device and no further internal calculation is needed.
Most vendors of monitoring solutions charge extra if you want to monitor IP SLA. Following Paessler's long term "all-in" policy we simply include this as one of our sensor types, with no extra charge. With PRTG you can even use the Freeware Edition to monitor IP SLA!
Note: Even if you do not have an IP SLA enabled device, you can still get similar information about line qualities with PRTG's QoS sensors.

2. SNMP Cisco ADSL Sensor

With the SNMP Cisco ADSL (Asymmetric Digital Subscriber Line) sensor, PRTG offers a solution to monitor the ADSL statistics of your Cisco router. Because it queries the data via SNMP, it only requires minimal bandwidth and CPU cycles to help you keep track of:
  • Downlink and uplink
  • Remote and local attenuation
  • Remote and local SNR (signal-to-noise ratio)
  • Remote and local power output
As you can see with the SNMP Cisco ADSL sensor, PRTG provides an easy and efficient way to monitor the connection quality of your Cisco router's ADSL connection.

3. SNMP Cisco CBQoS Sensor

With the SNMP Cisco CBQoS (Class Based Quality of Service) sensor, you can use PRTG to monitor your network parameters using Cisco's CBQoS via SNMP. This sensor supports the classes Class Map, Match Statement and Queueing and helps you monitor the following values:
  • Current and maximum queue depth
  • Pre policy packets
  • Pre and post policy size
  • Drop packets and size
  • Drop packets without buffer
  • Fragment packets and size
Because you and your colleagues usually work with bandwidth demanding IP applications and services to do business and, thus, rely on high QoS in your network, you probably already have implemented your own CBQoS policies on your Cisco routers. Besides IP SLA which is an active response time measurement method that uses reliable, scheduled continuous traffic generation to monitor network performance, CBQoS is a passive method to measure response time. This sensor is best used to monitor data that includes summary counts and rates by traffic class before and after the enforcement of previously defined QoS policies.
PRTG's CBQoS sensor helps you to:
  • analyze the different traffic classes in your network,
  • monitor the efficiency of your QoS policies,
  • and take the right measures when you need to amend your QoS policies to meet new challenges in an ever changing IT environment.

MRTG For Windows = PRTG

Masih ingat MRTG ? Pernah dengar MRTG For Windows ? Ya itu PRTG

What is MRTG?

MRTG (Multi Router Traffic Grapher) is a tool that monitors traffic on a network connections mainly using SNMP. Although useful, MRTG has its limitations, especially the complex installation on Linux systems. Many of its users have now discovered PRTG Network Monitor an innovative and user-friendly network and bandwidth monitoring tool.

PRTG - MRTG For Windows

Often described as MRTG for Windows, PRTG makes bandwidth monitoring easy. The products work with SNMP enabled devices, such as managed switches, routers and firewalls. Also WMI enabled Windows systems can be monitored as well as many other protocols. PRTG is remarkably easy to install on Windows XP/2003/Vista/2008. Monitoring is both simple and intuitive, and can be done via a web based front end. Data retrieval and configuration is easy, and the fully skinnable web interface makes it easy to customize reports to suit your business.

Choose between Freeware Edition and Commercial Editions

If you're looking for a professional LAN monitor that meets your bandwidth management needs, this MRTG-for-Windows product is exactly what you need. PRTG is available in two different editions. The Freeware Edition is completely free for both personal and commercial use. The Commercial Edition is suitable for those who need to monitor more than 10 sensors, and licenses start at $440/€330.
We think that PRTG is the ideal Windows alternative to MRTG - and we're not alone. Here are some of the comments we've received from satisfied customers.
  • "We just purchased PRTG and think its a fantastic SNMP tool and better than MRTG (not to mention it can be installed by a monkey)", Matt Brown, Data Sanctuary Internet Backup
  • I really think that you guys have made a damn good program here, and I have never regretted buying it from you. For the past 3 years I have been using MRTG and ever since I started using it I have been searching for a program like this one. So 3 words for your team, DAMN GOOD JOB.", Jeppe Jessen,
  • "We have purchased the PRTG software which I must say was a very easy product for us to install and has put our own MRTG installations to shame! A very good product.", Simon Jones,
  • "I am an avid supporter of PRTG and I would like to congratulate you on this most excellent product which really works very well and is very easy to use. You have identified a gap in the market for easy "MRTG"-style traffic management, and I have to say without your product I would certainly be lost. I stumbled upon PRTG in Google whilst again looking for an easy to use "MRTG"-style traffic graphing and immediately bought it. I have also encouraged my partners to purchase the application. My business is a Internet Service Provider and we also have a Wireless Internet Service Provider Division. I use PRTG to monitor all my critical links." Eugene van der Merwe,
