Alerts and Notifications

Alert decision-making algorithm

Quantellium provides two different algorithms (Static vs Device Rank based) for taking alarm decisions that are both aimed at drastically reducing the number of alerts sent. The default for new projects is Static. For more information follow this link..

Alert delay

Monitoring the uptime of devices via internet (or bad or slow WAN modem / copper connections) can lead to false positives. In this case, a “false positive” means that Quantellium labels a device “down” because it did not respond in time to an echo request, while the real cause was a bad connection.

The “False positive” ratio can be significantly reduced by introducing some “delay” (at the expense of the speed of a warning). Note that the event itself is not delayed, but only the triggering of the warning or warning.


This allows you to define how you are notified. There are two notification options:

  1. An array of colored event-type counters in the top-right corner of each web page.
  2. The same array of colored event-type counters as in 1, along with audible beeping. Click on the small speaker icon to open the “Pending events” page and mute the beeping

Email alerts

Information of an event can be send to one or multiple recipients through email. You can use any SMTP relay server, a Gmail or an Outlook account for sending alert mails.

In case of an SMTP server:
  1. Tag the Send using checkbox.
  2. Select the An SMTP server radio-button.
  3. Fill-in the IP address or DNS name into the SMTP srv input box.
  4. Optionally, provide a valid Username and Password.
  5. Save your settings by clicking the Apply button.
In case of a Gmail or Outlook account:
  1. Tag the Send using checkbox.
  2. Select either the A gmail account or An Outlook account radio-button.
  3. Fill-in the eMail address (e.g. and password.
  4. Save your settings by clicking the Apply button.

Google already announced in April 2014 that it would improve the login security of its Gmail services by disabling access to applications that log on with usernames and passwords. To enable the sending of e-mail messages via gmail, you must allow “Access for less secure apps” in gmail. Follow the steps described here..

Trap, Syslog and TFTP Servers

Trap server

Traps are unsolicited device notifications. Quantellium only accepts Traps from “known” devices (placed on a project map). Traps can be informational (port up / down, new user logged in) but also critical (fan problem, power failure).

In order not to miss critical device messages it is important to limit the number of incoming traps by adding trap filters.

Incoming Traps can also be forwarded to other systems (log management systems) for further processing. For more information on Trap filters read:

Syslog server

Syslog is a widely used standard for message logging. System- and network managers can use syslog for system management and security auditing as well as general informational, analysis, and debugging messages.

A wide variety of devices (such as printers and routers) and message receivers across multiple platforms use the syslog standard. Because of this, administrators can use syslog to integrate log data from different types of systems in a central repository. Quantellium provides a basic Syslog server.

In order not to miss critical device messages it is important to limit the number of incoming syslog messages by adding filters. Syslog messages can also be forwarded to other systems (log management systems) for further processing. For more information read:

TFTP Server

TFTP stands for Trivial File Transfer Protocol. TFTP is a mechanism to tranfer files from one device to another. It is typically used by the network administrator to copy configuration files, log files and firmware to/from networking devices. TFTP uses the UDP protocol over port 69. The MonitorONE G2 TFTP server is implemented as a Quantellium service. Read more..

Connection Utilization Coding (CUC) & Error Control (EC)

Connection Utilization Coding (CUC) is the Quantellium functionality that applies a color and width to a connection line according to its utilization.

Error control (EC) is the Quantellium program logic that tries to find the root-cause of a problem in case a device doesn’t respond to status requests anymore.

Home page & Styling

Project Home page

In a hierarchical multilayered map structure, only one map can be yout project’s Home page (a.k.a. the RootMap). The RootMap is the highest level Map. Browsing through the maps is like zooming in to a lower level map. You can use the Home page option to set which page should be shown after a user has logged in. There are two options:

  1. The pending events list.
  2. The RootMap (default). If no RootMap has been specified, the “Unassigned map” (mapID=0) will be shown!

Note that clicking on the big Q in the top left corner of the Quantellium web interface also opens your project’s Home page.

Add shadows (pseudo 3D effect) to the graphical maps?

The graphical maps can be displayed with or without (default) 3D shadow effect. Be aware that the 3D effect can have a significant impact on the performance of your browser while drawing maps!

Select the default font and font-size

You can adjust the font that is used in the Quantellium web interface to your liking. Be aware that your browser needs access to the internet for this feature since the Google web fonts are used. By default or in case your connection to the internet is down, the web-safe font Arial is used.

Show the address in the device caption?

A device’s caption can either show the device name only or supplemented with its IP address or DNS name.
