is the main application of the suite. It provides 24/7 monitoring of your network infrastructure (switches, routers, servers, firewalls etc), collects all kinds of statistical information and alerts when important events (device down, threshold exceeded, trap received) occur.

Quantellium is smart, stable, feature-rich and can be accessed through a stylish and intuitive web interface.

Quantellium is a service application to support 24/7 monitoring and runs on all Windows versions from 2008 onwards (32/64 bit, desktop & server). Supports SNMP version 1,2 and 3.

  • Functions

    Performs all relevant monitoring functions like Status, Uptime, Threshold and Performance monitoring out of the box.

  • Smart alerting

    Offers two different Alert decision-making Algorithms (ADA) to distinguish between important and less important events in an attempt to alert only for relevant events and thus to keep the number of alerts as low as possible.

  • Scripting interface

    Provides a comprehensive interface for executing applications or scripts triggered by alerts of occurring network events.

  • Alert emails

    Sends alerts by email by using a generic SMTP server (or smtp.gmail.com / smtp.outlook.com).

Clear topology diagrams

  • Interface

    Provides a stylish and intuitive web interface.

  • Topology diagrams

    Focuses on network visibility by providing clear network topology diagrams with live updating status- and event indicators per device. Connections between devices are added automatically based on the LLDP protocol.

  • CUC

    Provides unique features like Connection Utilization Coding (CUC), and Error Control (EC). CUC stands for Connection Utilization Coding. It shows the current utilization of connection lines on accompanying labels.

This is a screenshot of a small lab network for demonstration purposes. Quantellium has received a trap message from the Procurve switch and Syslog messages from the Linux servers Gold and Platinum and from the Windows server Cerium. The green tags on devices Poen99 and Cerium are an indication that these devices have been rebooted. Device Hafnium is currently down. The green color of a number of connection lines indicates that CUC is active for these lines. The grey color of other connection lines indicate that CUC cannot collect sufficient data to calculate the current utilization.

Performance and trends

  • Historical data

    Displays tables or graphs of collected SNMP data for performance- and trend analysis.

  • Dashboards

    Define Dashboards that help you keep an eye on critical components or trouble spots in your infrastructure. You can add multiple Performance graphs and/or Tables to a dashboard.

  • IP scan

    Provides an IP scan / auto-discovery tool (with filtering options) to speed up building network diagrams.

  • Listeners

    Has a Trap-, Syslog- and TFTP server built-in with filtering options.

  • Trap and Syslog message forwarding

    Trap and syslog messages can be processed by Quantellium locally or forwarded to specialized external servers or services.
