This is one of the common questions IT pros face in their job every day. Whether yours is a large organization with different teams for network and application management, or a small IT department with one IT guy trying to figure out where the problem is, the challenge of identifying the root cause is the same. Though the network and servers are part of the same IT infrastructure, they are two very different entities when it comes to monitoring and management.

 

Take the example of end-users complaining of slow Web connectivity and performance. Where do you think the problem is?

  • Is there a problem on the in-house network?
  • Is it a fault on the ISP’s side?
  • What about the IIS server?
  • Is it the virtual environment hosting IIS?

 

There could be many more possibilities to investigate. Making a list of questions and manually checking each part of the infrastructure is definitely what you don’t want to do. Visibility into the network and the application side of the house is key. Integrated visibility of network and application performance is the best thing an IT admin could ask for in this scenario.

 

As you probably know, Network Performance Monitor (NPM) v12 is out with NetPath™ technology. The power of NPM can be enhanced when integrated with Server & Application Monitor (SAM). In the image below, I’m making a modest attempt to explain the value of end-to-end visibility that you get across the service delivery path, from inside your network to outside your network, from on-premises LAN across the WAN and cloud networks.

 

PROBLEM/USE CASE

Users in both the main and branch offices are reporting slow performance of intranet sites. What is causing the problem and why? Is it the network, or the systems infrastructure that needs troubleshooting, or both?

HOW THE ROOT CAUSE WAS FOUND USING NPM and SAM

  • Using hop-by-hop critical path analysis available with NetPath in NPM to isolate problem in the ISP network.
  • Using application and server monitoring in SAM to pinpoint performance issue in the Web server environment.
  • The Quality of Experience (QoE) dashboard available in and common to both NPM and SAM analyzes network packets to provide insight into network and application response times for specific application traffic. This helps confirm the symptoms of the problem at both sides—network and the application.

 

BENEFITS USING NPM and SAM TOGETHER

  • One unified Web interface and NOC for monitoring and troubleshooting networks and applications infrastructure.
  • Eliminate finger-pointing between network and system teams. Find out exactly where the root cause is for faster troubleshooting.
  • NPM and SAM are built on the Orion® Platform, sharing common services such as centralized alerting, reporting, and management.
  • Easy to install, set up, and use. Automatically discover your environment and start monitoring.
