What Does Network Telemetry Replace ?
I’ve been thinking about what Network Telemetry will change in network equipment. It was this slide from Cisco Live that gave me a starting point: What it highlights is that poor quality of tools for troubleshooting. We have the CLI and Packet Capture. The CLI is expensive to operate because it requires highly trained and […]

Making the Leap to 25 Gigabit Ethernet and Beyond
Before adopting new Ethernet standards, consider these fundamentals.
Nexus 9K –ACI Mode – PART 1
SDN is the Buzzword for Network Guys, How is it related to Nexus 9k in API mode. Let’s Start with SDN to understand the co–relation between SDN and Nexus 9K (ACI Mode). To understand SDN in network terms, SDN does decoupling of control plane and data Plane, thus decision making now done at centralized […]
Webinars in This Week
The spring craziness is still in full swing – we’ll have three webinars this week (a first) and I was so busy I didn’t even have time to write about them. Let’s fix that.
Data Center Updates on Monday is the second part of server virtualization, virtual machines and containers update to Data Center 3.0 webinar. We covered virtual machines in the last session (April 25th), this time we’ll talk about containers.
David Barroso (now at Fastly) will talk about NAPALM in Ansible on Tuesday.

Savvius Insight and the use of Elastic
Last week Savvius announced upgraded versions of its Insight network visibility appliances. These have the usual performance and capacity increases you’d expect, and fill a nice gap in the market.
But the bit that was most interesting to me was the use of an on-board Elastic stack, with pre-built Kibana dashboards for visualizing network data, e.g.:
Historically the only way we could realistically create these sorts of dashboards and systems was using Splunk. I’m a big fan of Splunk, but it has a problem: Cost. Especially if you’re trying to analyze large volumes of network data. You might be able to make Splunk pricing work for application data, but network data volumes are often just too large.
Savvius has previously included a Splunk forwarder, to make it easier to get data from their systems into Splunk. But Elastic has reached the point where Splunk is no longer needed. It’s viable for companies like Savvius to ship with a built-in Elastic stack setup.
There’s nothing stopping people centralizing the data either. You can modify the setup on the Insight appliance to send data to a central Elastic setup, and you can copy the Kibana dashboards, and create your own Continue reading
