Capturing Application Transaction Real Time

Why capturing application transaction real time?
Network-aware NPM solutions have provided a visibility into TCP level performance; having a broad view of whether the degradations comes from the network conditions, the server processing time or the quantity of data sent back and forth still has value. It enables IT operations to pinpoint the origin of a broad performance slowdown.

Nowadays people need a precise vision of where applications are failing to deliver a proper performance and to quickly identify transactions with errors and slow response times.

A diagnostic should not require any complex post treatment and transactions should not be presented as …

TTFB (Time To First Byte) – A metric to use with precaution

The TTFB (Time To First Byte) is a metric in network metrology. It is the time elapsed between the opening of a TCP connection between a client and a server, and receipt by the client of a first packet with payload from the server.


Time To First Byte (simplified)


A common measure

The TTFB is a common measure in metrology, this for two reasons.

The first is that it covers a number of possible causes of performance problems. As shown in the diagram above, the TTFB contains a part of…

Performance impact of encryption: a case study!

Is the treatment you execute on a flow neutral from a performance point of view?
Well… it depends how fast it is performed. If you have the article on the drivers of network latency (, you will probably see what we refer to. The processing job performed by network devices may not be neutral.

Here is a concrete example of a network connection which gets encrypted for security reasons. Here is what we could observe from a performance point …

APM: Taking IT monitoring beyond the limits of SNMP

SNMP Based monitoring is the starting point of an IT Service Management initiative

Polling data from critical devices has always been the basis for any IT monitoring system: it is the starting point for any monitoring systems. These platforms always provide a global view of all the critical devices in your IT system to control their availability and level of resource consumption.
Most traditional monitoring systems whether commercial software (e.g. BMC Patrol, HP IMC, ManageEngine OpsManager, Solarwinds NPM, Ipswitch What’s Up Gold, CastleRock SNMPc, CA Nimsoft) or open source (Nagios, Centreon, Cacti etc…) rely on a set of methods to control the …

Webinar – HTTP Application Performance Troubleshooting

HTTP applications concentrate many performance issues:

  • They are a common way to let internal & external users access and modify data.
  • They rely on a delivery chain which contains many elements, which are all performance drivers: browser, workstation, network, front-server, application server, file server, database, images, etc…
  • They raise specific troubleshooting issues: among others, the end user feedback is based on the concept of page, while most network based performance analysis is based on every transaction / object in the page (html, css, image, script, etc.)

This one-hour webinar will enable you to:

  • Understand the challenges of performance troubleshooting for HTTP Applications.
  • View a …

Integration of WhatsUp Gold and Performance Vision

By integrating Performance Vision data into WhatsUp Gold, you can monitor network and application performance through the same solution as the availability and resource consumption of your IT infrastructure. Our distributor in Singapore, AsiaVAD, nicely drafted the new possibilities that this integration creates.


Ipswitch WhatsUp Gold is a popular network, server and application monitoring solution, support versatile monitor protocols such as SNMP, WMI, Service Running Check, Network Port, Scripting support, Disk/Memory Utilization Monitor, for wide range of devices include router, switches, firewall, servers of various OS, application servers.

SecurActive’s Performance Vision (SPV), is a network-based APM [Application Performance Monitoring] solution, …

Graphing Network & Application Performance with Cacti and Nagios

Performance offers an open SNMP MIB to integrate its performance data into external tools, like Cacti.

This offers users of opensource SNMP graph tools such as Cacti, MRTG, Centreon, Nagios or commercial SNMP solutions like What’s Up Gold, PRTG, SNMPc an opportunity to integrate into their monitoring toolbox network and application performance metrics.

You can for example integrate data like:
– Packet counts
– Bandwidth
– RTT response times (network latency)
– End User Reponse Times
– Server Response Times

Performance Vision data into Cacti

You can read a step-by-step guide on how to …

Version 2.12: Breakthrough in Performance Mapping

Performance Vision version 2.12 brings in a revolutionary network and application performance display: the Performance Matrix.

Some of you may already know the network traffic matrix, which displays the volume transferred between network segments as a map from zone to zone. It had been a killer feature of our previous product generation, NSS, and also one much appreciated by our Performance Vision customers.

It became even more relevant with Performance Vision’s multilayer zones. It was one feature used for many varied use cases: evaluating where an application is used, in what volumes to identifying abnormal behaviors and traffic.

In version Performance Vision version …

Agentless Performance Monitoring for Citrix

Performance Vision applies its application recognition engine to identify and monitor Citrix Metaframe Presentation Server traffic (from thin clients to Citrix servers) and Citrix hosted applications (from Citrix servers to the application servers), mapping their traffic volumes and reporting performance indicators to the real time and historical reports of the GUI.
Agentless Monitoring of Citrix Applications
This approach enables Performance Vision (placed in strategic points of capture on the network) to collect and provide rich insight on the utilization and performance of each published Citrix application. Network administrators can then proactively manage faults, monitor individual Citrix based applications, plan capacities and troubleshoot …

Step by step guide to analyze DNS performance

When you experience a performance degradation on a network, it may not be due to the server nor to the network or application. The root cause may be a DNS issue at the workstation level or between the different tiers of the application chain. For example, a Web portal, accessing to its database, via a DNS request which is very slow.

A key to diagnosing DNS issues quickly is to validate the behavior of DNS on all steps of your application chain.

The name resolution protocols are translating a known IP address (information of the network) and a name which is more …
