Build 1.2.15 released for selected POC customers. Download Current list of major features that are available out of the box without special licensing: Network Discovery Network Monitoring (SNMP v2/v3) Netflow Collector (requires second VM for storage) Syslog Server SNMP trap Server Network Topology Visualization HTTP URL Monitoring SQL Server Monitoring (new feature) Windows Server […]
Recently I was pinged in LinkedIn by some recruiter for a job with a title “Splunk Network Architect”. I 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 […]
Today 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 […]
Keeping 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 […]
Version 1.2.16 released on November 15, 2017 added ability to monitor Microsoft SQL Servers. Monitoring for 75 different SQL server metrics. Server, Instance and Database level statistics. Dashboard Example:
Starting from Nectus version 1.2.10 we added ability to monitor any HTTP URLs for up/down status and latency. Configurable polling intervals and URL dashboard added to standard list of dashboards. “URL Down” alerts can be sent via email or SMS/text messages. GSM Modem is required for text based alerts.
We offer NetFlow Traffic Generator utility that can send up to 30k flows per second with randomized parameters. This tool is ideal for anyone who is developing Netflow Collector functionality. Allows to generate large amount of NetFlow packets for protocol versions: 5, 6, 7, 8, 9 as if they were coming from real routers or […]
This is an example of how Nectus overlays real-time performance data on top of network diagrams.
If 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 […]
Starting from version 1.2.7 Nectus adds new “Storage and Memory Utilization” reports for Windows and Linux Servers (VMs or Standalone) We can monitor and alert on: Low HDD free space, High RAM or High Virtual Memory utilization for any Windows/Linux Server. Reports are based on SNMP hrStorageEntry OID (1.3.6.1.2.1.25.2.3.1)
Following Netflow reports are available for all Nectus Suite users starting from version 1.2.6 Top Flows by Protocols Top Flows by Application Top Flows by BGP AS Source + Destination Top Flows by BGP AS Source Top Flows by BGP AS Destination Top Flows by IP Source + Destination Top Flows by IP Source Top […]
You can clone network topology diagram to multiple windows for up to 5 x 5 grid an overlay different information in each cell
It 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 […]
Here is the list of the the possible reasons why some of the network devices can be missing after Network Discovery: SNMP is not configured or misconfigured on missing device (Test SNMP operation via Tools -> SNMP Walk). SNMP ACL on missing device does not permit requests from Nectus IP Address (Test SNMP operation via […]
During 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 […]

One of the first steps that we normally perform during POC is timer tuning for ICMP and SNMP for Discovery and Monitoring services. Normally Discovery should have different timer values than Monitoring because Discovery operates in a “pessimistic” model when IP address that is being probed by Discovery engine is likely not to be alive […]
Nectus Network Discovery engine is one of the fastest among all that I worked with .. and I worked with most of them (Cisco Works, Prime, Solarwinds, ManageEngine, Remedy, BMC) I remember when it took Cisco Prime to scan 10.0.0.0/8 whooping 24 hours. Nectus finishes 10.0.0.0/8 in under 3 hours. Speed of the discovery is […]
One of the unique features of Nectus Syslog service is ability to alert users via Email or Text messages not only on Syslog message Severity level but on specific keywords inside Syslog message. For example you can configure a rule to alert via email when there is Syslog message with Severity 2+ and there is […]
I was working with a client today on Nectus POC and he asked me to generate a list of all the routers and switches that have problems with TACACS. Nectus didn’t have “out of the box” report that validates the SSH connection to each device so we had to be creative in this case. Fist […]
