Real-Time Monitoring: Almost Always a Lie

PerformanceManagementIn Understanding the Value of Unique Management Data, we pointed out that tools that collect unique data about the performance of infrastructure and applications are more likely to be able to provide you the value you want than tools that just rely on commodity data. In this post, we expose the most frequent marketing lie in the management software industry. Continue reading Real-Time Monitoring: Almost Always a Lie

The New Management Platforms for the SDDC Management Stack and the Cloud

Legacy solutions from IBM, BMC, HP and CA are not going to be the foundations upon which the management stacks for virtualized data centers, the SDDC, private clouds, hybrid clouds and public clouds will be built. Rather a new ecosystem of management vendors is going to emerge with a new set of leaders providing the core platforms around which the SDDC and clouds are managed.

News: Compuware PureStack adds a Focus on Application Operations

PerformanceManagementThe traditional view of APM is that APM has been 1) all about custom developed applications, and 2) all about finding the problem in the custom developed code that is creating the performance, throughput, or availability problem. However, as more an more applications are being put in highly distributed, shared, dynamic (virtualized), and cloud based environment, it is increasingly becoming the case that problems in the infrastructure are impacting the applications.

APM as a Service and CA’s Reaction

BlindDinosaurLegacy management software vendors like IBM, HP, BMC and CA are in deep trouble. They are in trouble across their entire portfolio of management solutions due to two simple facts. Their products are not suited for the new dynamic and distributed IT environment, and the way in which they sell and market those products is inconsistent with how the new buyers of management software want to buy those products. A great example of the trouble that legacy vendors are in is how CA and its APM solutions (Introscope) stack up against modern solutions like those from New Relic, AppDynamics, and Compuware/dynatrace.

On Premise vs. Monitoring as a Service – Considerations and Tradeoffs

PerformanceManagementWe all pretty much know that we can buy Infrastructure as a Service (IaaS), Development/Run time Platforms as a Service (PaaS), Software as a Service (Saas), Security as a Service, Cloud Storage as a Service, among other things – but we can also buy monitoring as a service. We can buy monitoring at both the infrastructure level and the application level as a service. This is an intriguing idea, and one that is rapidly gaining traction. However Monitoring as a Service (MaaS) carries with it some unique benefits, but it also carries with it some trade-offs especially when evaluated against on-premise solutions.

News: ExtraHop Releases Network Aware APM Virtual Appliance

ExtraHop is a “network aware APM” vendor that has historically focused on putting an appliance on a mirror or span port of a switch and then using deep packet inspection techniques and TCP/IP flow analysis techniques to understand the performance of applications running on the network from the perspective of the network.  Today, ExtraHop has announced the addition of a virtual appliance to its product line – allowing for the data collection appliance to be implemented entirely in software, and to us the virtual mirror port on the vSphere vSwitch to collect its data.

Adding a virtual appliance to the product line allows ExtraHop to accomplish two very important new things. The first is that conversations between VM’s on one host are now visible, and their response time can now be part of the picture of the response time of the entire application. But the second is far more important. Since ExtraHop can already measure the true performance (end-to-end response time) of every application on a physical TCP/IP network, adding the virtual appliance means that now ExtraHop can cover both the physical network (and applications that are not virtualized yet), as well as the virtual network (covering applications that are either completely or partially virtualized).

The New p2V Process

It is very clear that the difficulty of virtualizing business critical applications for many enterprises means that for business critical and performance critical applications the P2V process is either broken or completely fails to exist in a relevant manner. Measuring how much CPU and memory and application uses is a necessary but a completely insufficient step towards virtualizing a business critical application.

What is required to virtualize a business critical and performance critical application is a P2V process that is focused upon the performance of the application in the eyes of its owner and its owners. That means that performance is equal to response time, not resource utilization. This process must therefore start with building a response time and load profile of the application in its physical home, agreeing on the aspects of that profile that will be the basis of the SLA when that application gets virtualized, and then continuously updating that profile as the application gets virtualized.

Criteria for Application Performance Based P2V

With this announcement ExtraHop joins the fray for the set of solutions that are viable candidates for being the basis of an applications response time based P2V process. The criteria for selecting such a tool are:

  • Ability to measure response time for every application in the environment (or at the minimum all X86 applications that use TCP/IP).
  • Ability to automatically discover the applications in the environment and their topology
  • Ability to automatically measure response time for each application end-to-end and hop-by-hop
  • Measure response time on a continuous, real-time, and deterministic basis. This means no averages, no sampling of data, no synthetic transactions. It means seeing the response time for every transaction over the network, and being able to pass the slow ones up to the management system in real time.
  • The solution should work in the existing physical environment of the application, in the new virtual envionment of the application and any mixture of the two.
  • The diagnostics in such a solution should focus on providing pointers to where in the virtual and physical infrastructure the problem likely lies, as opposed to pointing to code issues which is what developer focused tools do.
Who to Pick From?

Other than ExtraHop there are two other solutions that are appropriate IT Operations oriented (as opposed to developer oriented) solutions. Those two solutions come from BlueStripe and AppFirst. All three of these solutions are profiled in an upcoming post about the use of these solutions in the context of the new capabilities of VMware vSphere 5.0.


ExtraHop has now made an important contribution to the question of how to measure applications performance across physical and virtual environments. Properly deployed ExtraHop can play a critical role in helping enterprises virtualize the 60% of the remaining applications that are “hard”, “performance critical”, and “business critical”. As vSphere 5.0 is right around the corner, the timing could not be better.

ExtraHop Creates Fastest Virtual Application Performance Management (APM) Solution with New EH1000v Appliance

ExtraHop’s New Virtual Appliance Provides Ideal APM Solution for Branch-Office Deployments and Virtual and Cloud Environments

July 10, 2011 – ExtraHop Networks, a leading provider of network-based application performance management (APM) solutions, today at Cisco Live announced its virtual appliance for APM, the EH1000v. The new appliance furthers ExtraHop’s commitment to building the fastest APM solutions available by providing real-time transaction analysis at up to 1Gbps speeds for applications running in virtual and cloud environments—more than 10 times faster than competing products. As a virtualized version of the company’s passive, network-based ExtraHop Application Delivery Assurance system, the EH1000v delivers a small-footprint solution for branch-office deployments and offers deep, end-to-end application visibility for virtualized environments.

The EH1000v virtual appliance lowers IT infrastructure requirements for monitoring network and application performance across geographically distributed environments. In line with Gartner’s prediction that 20 percent of companies will own no IT hardware assets by next year, the EH1000v eliminates the need to ship and install hardware for each geographic location. With more companies using virtualized systems in remote-office applications, the new virtual appliance from ExtraHop Networks will help these organizations deploy and remotely administer a powerful monitoring solution for branch-office deployments that also can monitor traffic within virtualized environments.

As they have increasingly virtualized their systems, many organizations have lost visibility into transactions passing between virtual machines on the same physical host, leading to a growing blind spot for heavily virtualized organizations. According to an InformationWeek survey, nearly 50 percent of companies using APM solutions run more than half of their applications in virtualized environments, creating a significant amount of traffic that enterprises cannot see on the network. The EH1000v can monitor traffic that passes only through virtual switches and restore deep visibility into applications running in such environments, even those with large traffic volumes among multiple virtual machines.
“While server virtualization offers many benefits such as flexibility, scalability, and lower cost, it also can limit visibility into virtualized environments,” said Jesse Rothstein, CEO and co-founder, ExtraHop Networks. “In these cases, the physical limitations of many APM solutions present obstacles to monitoring application performance. The EH1000v gives companies a small-footprint solution that helps them to get around these roadblocks and realize the benefits of virtual and cloud technologies without compromising application performance.”
