Application Performance Troubleshooting and Audit

Our Mission

Network troubleshooting is the collective measures and processes aimed at identifying, diagnose and resolve problems in computer networks. It is equally effective to optimize the network.

For over twenty years, COMCERT specializes in troubleshooting for small and large businesses and organizations. Whether you have a basic local area network (LAN), sophisticated wide area network (WAN), virtual private network (VPN), wireless network, or a hosted networking solution, our specialists are here to help.

We offer a large selection of onsite and managed network services covering the complete range of network operations.


Our Philosophy

We at COMCERT understand that anytime the network goes down or a service becomes unavailable, a business is profoundly and financially affected. We are committed in helping our customers to identify the root cause of the problem, whether it be the network, the server or the application.

We believe that our ability to offer impartial diagnose and reengineering advice is a direct result of our commitment to never sell network equipment. It allows us to work in close collaboration with our customer’s existing service partners and hardware suppliers.

Close partnerships with major players in the field of network instrumentation such as Fluke Networks and Netscout has led to a vast and up to date arsenal of test and measurement devices allowing us to identify and remediate the problem fast and accurately in both physical and virtual environments.


Application Performance Troubleshooting and Audit

"The network is slow " must be the most widespread misconception in networking history.  Any user experiencing application responsiveness that doesn't meet expectations, blames "the network". That "network" is the intricate yet for the most part hidden system of computers, network devices, servers and software, all collaborating to serve the business process. When the application doesn't meet service acceptance criteria, the network operator must differentiate between those system components to avoid finger pointing and remediate the problem swiftly.

Our APT service aims at finding the root cause of the problem by identifying the fault domain to be either client, network, server or software. That triage allows the network operator to invite specialist teams (and us) to investigate the problem in great detail.

APT is equally effective to audit or baseline a business critical application before and after a major upgrade or at regular intervals. 

All metrics are derived from the observation of real user transactions, without installation of software on your servers. Our tools are capable of analysing hundreds of thousands transactions a minute between users and front-end servers and between back-end servers.

Service Process

  • You describe any problems, recent changes, unusual events and key application servers
  • We discuss the purpose and goals of the service to the team
  • We provide a template so you can create a detailed overview of the business application to monitor, including servers, protocols, ports and dependencies
  • We determine what devices and servers we need to monitor and what's required for packet capturing. This usually implies creation of SPAN, TAP or port monitors on switches
  • We configure our tools based on the documentation you provided, validate and - if necessary - correct the configuration 
  • We start our long-term analysis under your supervision and with minimal disruption of your business
  • In some cases – especially when the problem is intermitting - you will be asked to create a journal that can lead us to proper identification of the network symptoms, relating them to user-level complaints
  • Typically we need to monitor a business application for one month before we reach a final conclusion. We keep you up to date on our progress, hypothesis and findings
  • We draft a comprehensive and customer-specific report that is presented live to your team; you can ask questions and even challenge our conclusions
