Peter Nolan ExtraHop dropped by to let me know about their newest messaging in their quest to be the leading application and end user experience performance monitoring company. The company believes that APM and EUEM tools should cut across all of the tiers of a distributed, multi-tier application environment to gather operational data and should be built to understand how applications work. That capability, the company would say, would allow tools to be able to easily detect anomolies and allow IT administrators to prevent slow downs and failures.
They believe that tools should be able to follow and understand the entire flow of communication between and among application components, operating systems, data managers, storage systems and network components. In their words, products should be able to do the following:
- Be able to tell if there is communication going on at all – this is what a traditional network probe offers
- Understand who is talking with whom – this is was a network flow management tool offers
- Understand what words are part of the conversation – this was what a packet inspection tool offers
- Understand what words are typically used together – this is what a multi-packet inspection tool offers
- Understand both sides of the conversation – they’re calling this full-stream assembly
- Understand what is being said – they’re calling this full-content analysis
- Understand what the conversation means – they’re calling this transaction analysis
ExtraHop would pose that the best way to accomplish this is fully understanding the network dialog going on between systems and components rather than merely instrumenting individual pieces or inserting monitoring tools into application or virtualization managers.
While what ExtraHop has to say rings true to me, I’ve heard the same things said by many others. A few other competitors that are singing similar songs that come immediately to mind are eG Innovations, Netuitive and Prelert. I’m sure that if I did a bit of research on the subject, I’d come up with ten or fifteen other competitors.
Some of these competitors are trying to add “machine intelligence” or “predictive analytics” to the tools that are monitoring and managing complex distributed systems.
In the end, it appears that competitors in this market are all bringing very interesting approaches and technology to the market, but are having trouble articulating what they do without using the exact same language being used by others. ExtraHop faces this challenge.
So, an IT decision-maker is just going to have to do his/her own homework and speak with a number of competitors to decide which tool or combination of tools would best fit their own organization’s requirements.
