The processes – both internal and external – of a company are increasingly dependent on technologies. Regardless of the size or area of operation, every company needs to have a network system that fully supports the information that circulates through it on a daily basis. Therefore, in order to help performance, improve and enhance its network infrastructure, Nap IT Network Solutions, a Brazilian company specialized in corporate networks and integration of IT solutions, has adopted PRTG Network Monitor, a network monitoring tool from Paessler AG.

"After testing several pilot projects at Nap IT, we chose PRTG for its being a complete monitoring solution, its easy configuration and installation. And, moreover, as we implemented solutions with Cisco equipment, the Netflow resources and the large number of ready sensors dedicated to this manufacturer are widely used and help us establish capacity and use indicators for the computer network," says Klaus Engelmann, Network Engineer at Nap IT.

In the market since 2011, Nap IT operates with a consulting service methodology, through the innovative concept of Network Tuning, which customizes the technologies to deliver high-performance networks, with the best cost-benefit ratio. Its advantage is that the equipment operates redundantly and with high performance, avoiding investment in new equipment when not necessary.

According to Engelmann, "with PRTG we are able to obtain proactive information on the indicators of a network or systems, so that incidents are dealt with before causing an impact on users. We also created the use history of a network of computers and systems, to establish the standards of use and the capacity of the network, and thus understand how much is within or outside the normal range of behavior."

"PRTG helps generate alerts about incidents that impact our customers' network operations."

With PRTG installed on two servers running Windows Server 2012 and Windows Server 2008 R2 with VMs (virtual machines) of 8 GB of RAM, Nap IT configured about 500 sensors that monitor approximately 300 switches, 120 routers and 20 servers installed in the customers' data center, with IP-SLA that validates the response time of applications and their availability.

The monitoring happens in internal networks (switches, servers) and external (routers, Internet links), and the most used sensors are NetFlow, IP-SLA, ICMP, Bandwidth and also the HTTP Advanced sensor that monitors the source code of a web page and can show loading time, bytes received and bandwidth speed. Nap IT's IT staff uses the PRTG tool on a daily basis, preferably through the Web Interface and Mobile Interface versions of PRTG.

Currently, the focus of the implementations of Nap IT is the use of the PRTG solution to monitor equipment and services of computer networks. The PRTG was used in two major projects: migration of the WAN Provider, to establish a standard for using the WAN network and monitor its availability, in addition to the renewal of the LAN network in order to monitor systems and act proactively against incidents.  Among the most important PRTG resources, pointed out by Nap IT, are NetFlow, IPSLA and Cisco Health Status.

"PRTG helps generate alerts about incidents that impact our customers' network operations," explains Engelmann. "In this way, latency and unavailability of the IT infrastructure are avoided, which is something essential to ensure business continuity in the case of customers working with retail sales," he adds.
