1. Auvik – FREE TRIAL

Tested on: Cloud/SaaS

Auvik Dashboard

Auvik is a network monitoring solution that is hosted in the cloud and comes with a variety of tools for managing systems. The package can be accessed using a web browser, and the installation process for the collectors on your machine begins when you create an account with the provider. The Auvik package enables monitoring of various locations while also centralizing control over those locations. Because of this, the package is perfect for monitoring a wide area network (WAN).

Key Features:

  • A subscription to a cloud-based service that provides processing power.
  • Allows for the centralized monitoring of networks across many locations.
  • Maintains vigilance over the operational states of network devices.
  • Choose between two different pricing tiers: Essential and Performance.
  • Analysis of network traffic is included in the more expensive package.

The process of discovering networks is where the service provided by Auvik gets started. This causes the monitor to immediately generate all of the fundamental data that is required for it to function properly. Since the discovery service is always running, it is always able to detect when new devices are connected to the network.

When the monitoring service is put into operation, the system will sound an alarm whenever any of the predetermined limits are exceeded. Because of this technique, technicians can go on to other activities, secure in the knowledge that the thresholds provide them enough time to prevent problems with system performance that would be obvious to users.

The processing power that is used by Auvik comes from the cloud servers that are part of the service. However, for the system to function properly, each monitored location must have collectors installed. Both Windows Server and Ubuntu Linux are supported by this software. Additionally, it is doable to operate the collector within a virtual machine.


  • Cloud-based but with a local agent
  • Acts as the SNMP Manager
  • Creates an inventory and a network diagram
  • Constant device status monitoring
  • Option for traffic monitoring as well


  • No on-premises option

Auvik is available on a 14-day free trial.


Auvik is our top pick for a network device monitoring service because it adds traffic monitoring to its device monitoring service.s Buyers who just want that SNMP-based device monitoring service should look at the Essentials edition. The Performance edition provides network traffic monitoring services as well as device monitoring. This cloud-based service allows network managers to monitor multiple sites from one dashboard and the console is accessed through a Web page, so it is accessible from anywhere.

ManageEngine OpManager Overview

ManageEngine OpManager provides monitoring for networks, servers, and virtualizations. It is based on the Simple Network Management Protocol, so it is able to send out broadcast requests for reports from SNMP device agents. Each device agent responds to the request with a report called a Management Information Base (MIB). By compiling MIB data, OpManager is able to create a network inventory and draw up a topology map.

Key Features:

  • Discovers and maps all network devices
  • Creates a network inventory
  • Provides continuous device monitoring
  • Gathers port activity reports
  • Covers wireless networks
  • Includes troubleshooting tools, such as Ping

The OpManager system repeats its MIB requests continuously and this provides live network device monitoring. Details in the MIB also let OpManager know if devices have been added, moved, or removed. The system updates the network inventory and redraws the topology map automatically in response. This system also sees when rogue devices connect to the network.

Other functions in OpManager provide monitoring for Hyper-V, VMware, Citrix, Xen, and Nutanix HCI virtualizations. The system can keep track of internet connections between sites and out to cloud platforms.

The software for OpManager runs on Windows or Linux. It is also available as a service on AWS and Azure. The system can also be supplemented by the linked NetFlow Analyzer, which monitors network traffic.

The Network Monitor will poll the devices once per minute to obtain status data, and it will do so using the processes from the Simple Network Management Protocol (SNMP). The inventory and topology map will be updated to reflect any changes in the network infrastructure that are brought to light by the responses to these questions.

The dashboard of the monitor displays live data that has been interpreted based on the results of the device responses. The user can personalize the dashboard's panels and can access it with any browser that is considered to be standard.

If the SNMP system identifies a problem with the device that it is monitoring, it grants the device agents the authority to immediately issue a warning rather than waiting for a request to do so. These messages, also known as Traps, are detected by Site24x7 Infrastructure, which then causes an alert to be produced. This warning can be communicated to technicians via text message (SMS), email (email), phone call (voice call), or instant messaging post (IM post).

7. Datadog

Datadog Database Query Metrics

Datadog is responsible for monitoring how well network devices perform. The service is a cloud-based system that can investigate a network and identify all of the devices that are linked to the network. The information gleaned from this research will be used by the network monitor to compile an asset inventory and produce a topology map of the network. When this method is carried out, it indicates that the system will carry out its setup routines.

Key Features:

  • Consists of the monitoring of DNS servers.
  • Collects reports from SNMP devices.
  • Combines results obtained from a wide variety of information sources.
  • Including monitoring the flow of data.
  • Includes facilities for tag-based packet analysis within the dashboard.
