Been doing a few catch-ups with old vendor friends recently; one was Brocade - and more of this next month - which has a REAL SDN/NFV story - and another was NetScout; networking monitoring!!!! Except that network monitoring now goes way beyond SNMP probes and Sniffers.
Speaking with NetScout's Phil Gray, who came into the company with the acquisition of Psytechnics, which had a voice/video monitoring technology, two things became abundantly clear in terms of where network monitoring/analysis has been going since the days of analysing millions of lines of packet captures:
- A key requirement is getting rid of all the superfluous data automatically, so searches are focused purely on relevant information. Contrast this with the old days of spending hours looking for one hexadecimal string as the proverbial digital needle in an OSI haystack...
2. - Gauging/measuring by end user experience, not some theoretical mathematical improvement, is network monitoring for 2015. Importantly, the voice and video element of network data monitoring is, of course, more relevant than ever. Another point is that this traffic has to be captured at speeds and feeds from basic Internet level through to 40Gbps and above. This is not trivial stuff, just as identifying and preventing security attacks isn't. Yet the world of network monitoring doesn't get the mass media hype that security does but, at the same time, the key word that always comes up in IT conversations is "visibility". The bottom line is that traffic monitoring and analysis was important in 1988 and it's even more important - and relevant - here in 2015. Whether it's data trending, app performance management or simple data feed analysis, if you don't know what's actually on the network, how do you manage it?
