Very often I am invited to review new network related software products from other companies as an expert
in workflow and UI optimization. I always start with asking who designed the User Interface
and I see that in many cases user interface designer and a coder is the same person and that where all the problems originate.
Golden rules of best software design:
User interface defines functionality so start with it.
User interface has to be designed by Subject Matter Expert not by a coder.
Person who designs UI may haven’t written a single line of code in his life, but he knows the work flow of the trade.
Start coding it only after UI is complete.
Additionally..
If you developing best Network Management software, SME has to get involved in DB design in very early stages:
It is Network Export who must decide how to call fields in SQL table that will be holding BGP session information not a DBA.
It is Network Expert who must decide how to call columns in JavaScript table that User will be seeing in reports not a Web designer.
It is Network Expert who has to check with C++ coder how he named those procedures that will be used to read ISIS peering info.
This may sounds like micromanaging, but this is what my 20 years experience in managing software development projects tells me..

Using Nectus for Cisco VIRL Topology monitoring
Network Topology Visualization, Technical NotesOne of the limitations of VIRL that it does not provide real-time visual Up-Down status for Interfaces in your VIRL topology.
Pairing VIRL with Nectus give you best of both worlds. To allow Nectus to monitor your VIRL topology
enable and configure SNMP on your VIRL routers and ensure L3 reachibility between your VIRL subnets and
Nectus Server IP address. Define VIRL subnet in Nectus “Settings” -> “Network Discovery” and manually start discovery or
define discovery frequency which can be as low as every 6 min. After Discovery finishes your should be able to see your VIRL topology in Nectus GUI.
Enable monitoring for Interfaces to allow Nectus to send SNMP polls every 30 sec to each virtual router’s interface.

Why managing some network monitoring tools is a full time job?
Technical NotesI am not a job market but I guess some of the keywords it my profile rang a bell in their matching script
but what startled me is the job title: “Splunk Network Architect”.. Since when managing software tools becomes a full time job?
The golden rule here is: When software tool takes more times to manage than it saves, it is time to get rid of it.
With Nectus you don’t have to write custom Perl/Python scripts to get what you need, It is our developers’ job.
With Nectus you don’t have to install third-party macros… It is our developers’ job.
With Nectus you don’t need more than 5 mouse clicks to get any report. We actually counted it.
With Nectus you don’t have to hire full time Architect to manage it.
Nectus GUI is very intuitive, we have seen CEOs login and use it without any formal training :)
The most common words we hear when people see our Demo is: “Cool”, “Awesome”, “Where were you when we bought [network tool name]”?

Nectus sets new record in Netflow Collector speed: 50,000 flows per second
NetFlow IPFIX CFlow SFlow, Technical NotesToday we have achieved a new millstone with our Netflow collector performance:
50,000 flows per second processing speed was reached in Windows Server 2016 VM.
This rate was reached on VM with 64GB RAM and 1TB M2 SSD.
To simulate this flow rate we used 10 isolated instances of Netflow generator from Virtual Console (www.vconsole.com) with each instance generating 5Kf/sec.
There is no Netflow collector on the market that we are aware which can sustain this Netflow packet rate.
This explains why large cloud providers turn to Nectus for their Netflow processing needs when other tools fails to deliver.

We will update all of your network diagrams while you asleep..
Network Discovery, Technical NotesKeeping your Visio network diagrams up-to-date is a full time job and not a fun one.
For any decent size network there are always changes happen every day and it is almost
impossible to keep track of those not to mention about adding those changes manually in Visio files.
The time of manual, static network diagramming is over.
Nectus (www.nectus5.com) is a a tool that makes all the manual work from network diagram creation process obsolete.
Nectus is the most advanced network discovery tool on the market that can generate network diagram
of any part of you network. You only need to pick a starting point, right-click and Select
“Expand Network Topology” and awesome looking network topology based on information from daily network discovery
will be ready in seconds. Network diagrams are based on database of “interconnections” discovered
via CDP and LLDP protocols which Nectus uses during its scheduled discovery jobs.
So as long as you run your discovery every night you can wake up every day knowing that that all of your
network diagrams are up to date.
Microsoft SQL Server Monitoring added to Nectus 1.2.16
Technical NotesVersion 1.2.16 released on November 15, 2017 added ability to monitor Microsoft SQL Servers. Monitoring for 75 different SQL server metrics.

Displaying real-time interface utilization on Network Diagrams
Technical NotesThis is an example of how Nectus overlays real-time performance data on top of network diagrams.
Future of Network Visualization
Technical NotesIf you still using Visio for your network diagrams you are a dinosaur. You may be very good at it and have millions of very nice
looking stencils but your network diagram becomes obsolete the moment you finished working on it.
Network diagram made in Visio is what your think your network diagram looks like but not what it actually is.
Network changes every day, every minute, every second. Links goes down, IGP flaps, Spanning tree re-converges, BGP Churns.
Can you see all of that in Visio? Does your network diagram shows all the the action?
Can you see traffic distribution among LACP bundle members right on your network diagram in real time?
Can you spot asymmetric routing when you looks at Visio?
Modern JavaScript opens doors to an unlimited opportunities to making great web-based network diagrams on demand with
all the real time information overlaid.
If your Network mapping software does not give you all of that may be you are not using the right one?

Preventing false positives during device UP/DOWN Status monitoring
Technical NotesIt is important to distinguish between monitored device “down” event and event when monitoring application itself loses network connection.
When network monitoring application itself losses network connectivity it should not result in alert emails or text messages with monitored device
down events as it would be classified as false positive alerts.
To monitor its own network connectivity Nectus Server uses default ICMP probe for its default gateway with an inter- packet delay 3x faster
than normally used for monitoring all the devices. This allows Nectus monitoring service to detect loss of network connection faster than any of the normal device probes
would return “device down” alert. If Nectus server detects that it lost network connection it stops all monitoring activity for 5 min.
Why not all of my network devices are discovered?
Network Discovery, Technical NotesHere is the list of the the possible reasons why some of the network devices can be missing after Network Discovery:
How Nectus finds rogue or misconfigured SNMP devices
Network Discovery, Technical NotesDuring installation user must provide a standard corporate SNMP v2 or v3 Read-only credentials to be used for network discovery.
For each live IP address Nectus tries to use standard SNMP parameters as a first choice but in addition to standard credentials Nectus attempts
to use some of the well-known SNMP strings such as v2 community “public”, “private”, “cisco”, etc.
This approach helps to find rogue or misconfigiured devices that would normally be left undiscovered and pose a potential security issues.
To manage list of “well-known” SNMP profiles go to “Settings -> Network Discovery Settings”.
