Monitoring business transactions over the network has never been more critical to operational efficiency. Yet, there’s much confusion over methodology.
The implementation choices consist of different deployment strategies (client-site or server-site, agent or appliance) and distinct monitoring technologies (active or passive). Each of these options has individual strengths and weaknesses. This series of articles discusses industry best practices for effectively monitoring business transactions in a global environment.

Part 2 of 2: Monitoring Technologies
Another important - and frequently contentious - decision for selecting a business transaction monitoring solution is whether to use active or passive technology. An active monitor emulates a client by periodically generating synthetic transactions according to some user-defined script. In contrast, a passive monitor measures the transactions of real clients in all their variability. Which is better? Well, it all depends on what you want to measure.

Each of these options has individual strengths and weaknesses. This series of articles discusses industry best practices for effectively monitoring business transactions in a global environment.
Part 1 of 2: Deployment Strategies
One of the most important decisions is the deployment strategy for the business monitoring solution. Should monitors be deployed at the client sites or should they be deployed at the data centers? Should software agents or hardware appliances be used? While this may seem like a minor matter, it has the most serious ramifications from both an immediate “headache” and long-term recurring cost standpoint.

NetQoS VP Steve Harriman is attending the Gartner Enterprise Networking Summit this week in Las Vegas. It's the first time for the event since the industry downturn in 2001 and NetQoS is exhibiting there because we feel that the role of Networking has been elevated in importance to the point at which it warrants an executive focused event. And, Gartner events are always very educational and well-attended. It's the right place to be.
In addition to Dr. Malone's keynote and NetQoS's Solution Provider Session, I also went to a talk by Thomas Shelman on the second day of the Summit. Shelman is CIO of Northrop Grumman Corporation, the second largest defense contractor in the world. As you might imagine, he runs a very large IT organization. Seven CIOs from different business units report to him.
He said his greatest challenge and most rewarding experience, although devastating too, was leading the organization to restore computing and networking infrastructure and services after Katrina pounded two key Northrop Grumman facilities in Louisiana and Mississippi.
The two NG data centers in La. and Miss. were fully configured for redundancy with hot fail-over between systems in both locations. To ensure both data centers would not be affected by “traditional” disasters, such as local power failures, flooding, accidents, etc., they were located 150 miles apart. Unfortunately, the destruction of Katrina was more than 150 miles wide and took both data centers out. (Northrop Grumman put out a press release describing the devastation they encountered.)

The speaker for the second day’s keynote speech was Dr. Thomas Malone, Professor, MIT Sloan School of Management.
I noticed that a surprisingly large number of hands went up when he asked attendees if they had corporate blogs and if their organizations allowed individuals to have their own.
He discussed organization models and how organizations are becoming more distributed, both physically and in how they operate – more distributed decision making. Successful organizations have found the way to fully leverage the intelligence and creativity their employees have.
Employees who are empowered to use their capabilities to the fullest have more fun and are more productive. The networking tie-in here is that the network is the enabler of organizational empowerment.

It is worth noting that one of the key themes of the first day is that Network professionals should move beyond the plumbing and be part of the solution to the application delivery problem. The idea that network professionals need to look at response time and focus on end-to-end performance is a message NetQoS has been trying to spread. Here are a few details from the first day keynote to put this into context:
