Online school runs smoothly with network monitor

Originally designed to help reluctant learners gain access to the kind of alternative education they need for credit recovery or supplemental assistance, has developed into a comprehensive online education service, which helps schools individualize instruction, offers high-quality standards-aligned curriculum, and provides alternatives for students who need new ways to learn.

With so many students depending on to get the education they need, maintaining continuous and reliable access to the online curriculum is critical. To keep its network running at optimum performance and thwart critical failures before they occur, depends on Paessler AG’s PRTG Network Monitor.

Continuous Monitoring Ensures Access to Education’s Director of IT, T.J. Jones, and his support team are responsible for keeping the company’s network infrastructure operating at peak performance, using a combination of physical and virtual servers. With dozens of servers housing content at an off-site hosting center, it’s no small task to keep tabs on all the traffic flow.

“Our programs are used by at-risk students who need to recover credits, for those who just don’t assimilate well into a traditional classroom setting, and for those who have no other way to take a specific course that may not be offered in their district,” Jones said. “ Teachers and students access our materials from around the world, 24 hours a day, seven days a week. We cannot have outages.”

With hundreds of PRTG remote sensors deployed across the network, Jones and his team can keep tabs on every critical component, including CPU usage, available memory, the number of users querying a server at a given time, available disk space, network connections, traffic flow and more. In addition, sensors deployed to monitor the Microsoft Exchange server ensure email availability at all times, while sensors deployed at the off-site hosting center let the team know how many users are logged in, how many are accessing content, which pieces of content and when. This enables Jones and his team to track peak times and configure the system to handle the load without disruption.

“Paessler’s notification system triggers the sensors to alert us if a load is running heavier than usual on a particular server, allowing us the chance to reconfigure as needed to balance the load,” Jones said. “This allows us to be proactive, and see a problem coming before it brings down the system.”


In addition to delivering proactive notifications of network events, PRTG also helps control IT spending. With the ability to fully monitor all critical network components with a minimum of staff members, Jones estimates PRTG has helped to reduce IT staff costs by at least 25%. In addition, the company saves money by avoiding expensive server upgrades when a simple load redistribution would resolve the problem.

“We’re saving way more money a year than it costs us,” he said. “It’s a fairly inexpensive package to begin with, and it allows us to examine historical trends that tell us when an upgrade is needed, or when we can make a few configuration changes to better utilize our existing resources.”

In addition to the ability to deploy sensors on-the-fly to monitor specific components even for short periods of time, PRTG’s API interface enables Jones and his team to develop and integrate their own custom scripts to monitor for anything unique to their situation.

Reports Keep Team Up to Speed

Reports keeps the IT team—and upper management—informed of network events with charts and graphs that illustrate activity and offer the ability to drill down to see greater detail if needed. To keep an eye on network activity in real time, a 37” monitor located prominently in the department scrolls through screens of network data, displaying CPU usage, RAM and activity load for each server.

If an event occurs after hours, team members receive instant alerts by SMS, email or telephone. Within minutes, Jones can use his Droid to log in to the PRTG control panel, pause the sensor, assess the situation and determine whether a trip to the office is really necessary, or if a solution can wait until the next business day.

“The bottom line is that customers don’t care what went wrong or whose fault it was—they just want to be able to access their materials,” he said. “PRTG not only helps keep our network running at optimum performance, but also helps safeguard our reputation.”
