Network performance
Performance Vision provides a series of views on how your network is behaving. Here is a selection of views you should absolutely use:
Business Critical Networks
Provided you have configured some critical networks (setting thresholds on volume and quality indicators between 2 zones), you will get a summary screen of the performance of your most critical network links on this screen. This is an auto-refresh screen, whose data can be integrated in your SNMP based monitoring suite.
By pointing a specific time and link, you can view the origin of a degradation (latency, retransmission, excessive bandwidth consumption, and in which direction it …
Virtualization is widely spread and raises some new challenges for network analysis and network based APM. To analyze and troubleshoot performance degradations in application chains which are partially or totally virtualized, you need to capture virtual traffic (i.e. traffic between virtual machines which does not go through the physical network).
Depending on the virtualization architecture in place, many options are available; there is no perfect choice whatever the environment and constraintes are. The right option depends on your specific context:
This presentation covers:
- Definition of APM
- Comparison of APM approaches & vendors (scenario, agent and network-based)
- Challenges of Cloud & Virtualization for APM vendors
- Performance Vision’s Virtual Appliance offering
Workshop APM in a Cloud & Virtualized environment

3 main APM families, 3 working methods:
End User Experience
- A robot replays predefined scenarios to evaluate the overall end user transaction time.
Agent based APM
- Agents on all servers in the application chain monitor the execution of the application at code and system resource level.
Network based APM
- A set of probes captures the application traffic over the network (between clients and front server and eventually within the application chain).

Here is a question that we had recently: in which direction should we search to identify the source of the problem in the following table and solve it?
First comments:
We immediatly notice that the SYNs do not end up in a TCP connection. Thus, we can conclude that SYNACKs and/or ACKs are not issued or are dropped.
At the worst, there could correspond to machines infected by a virus trying to spread through the network!
This first observation turned out to be wrong…
Effectively, this is impossible because there are also …
Virtualization is now a standard practice in IT infrastructure to reduce costs (hardware and administration) and develop redundant server infrastructure more easily.
Cloud deployments are not yet so common, but these projects have similar goals, with similar consequences on performance and network monitoring.
Private & public Cloud architectures will also be very attractive:
They offer you to reduce costs,
They offer a simpler and cost effective path to a more robust and redundant IT.
The most common cloud deployments take the form of SaaS (software as a service) or cloud infrastructure purchased by software vendors to offer SaaS.
Virtualization and cloud solutions are …
