Auvik is a cloud-based network monitoring system that includes a number of system management tools. The package is accessed through a Web browser and when you open an account, the setup process installs collectors on your system. The Auvik package is able to monitor multiple sites and centralizes their control. This makes the package ideal for monitoring a WAN. The service provided by Auvik begins with a network discovery process.
This automatically populates all of the base information needed for the monitor to work. The discovery service is continuous, so it will spot when new devices are added to the network.
As a cloud-based system, Auvik is designed for remote system monitoring — even your home network is remote to the processes on the Auvik servers. Network monitoring works on a system of thresholds.
The service tracks a list of metrics on network activity and a threshold for resource usage or system performance is added to each of these conditions. If that threshold level is passed, the Auvik service will generate an alert. The Auvik service can be expanded through the use of third-party tools for which the network monitor has integrations. There are two plan levels for Auvik — Essential and Performance.
The Performance plan is the higher plan and it offers traffic analysis functions and Syslog management on top of the network monitoring services that are available in the Essentials plan.

Datadog Network Performance Monitoring includes a network discovery feature that tracks down all devices connected to the network, logs them in an inventory, and depicts all of the links between them. The agent gathers information and sends it to the Datadog server where all processing occurs. The console of the service is accessed through any browser. Being a cloud-based service, the Datadog Network Performance Monitoring module can map local and remote networks and also include internet connections to cloud-based resources.
The network view enables the user to change perspective, selecting to see a single device and all of the connections to it, a complete view of the network, or a focus on the links that run between to endpoints. The network map is live so it gets redrawn if any devices are moved, added, or removed.
The network topology map is interactive and acts as an interface through to details on each device. The data flows traveling around the network and through each device are also shown on the network map. An examination of a specific device offers details on the data throughput of that piece of equipment and status reports on its performance, shown both in graphical format and as event lists.
Traffic views shown on the network map can be segmented by application, or by endpoint, so it is possible to work out which devices or applications are generating the most traffic. The tool has other options that include the ability to analyze traffic patterns and see where devices and links get overloaded.
This is a great tool for capacity planning and forecasting. The Network Performance Monitoring module of Datadog is charged for on a subscription basis with a rate per host per month and also a cheaper annual rate per host. However, whichever payment cycle is chosen, the whole time period has to be paid upfront. Datadog offers a day free trial of the Network Performance Monitoring module. Site24x7 is an infrastructure monitoring platform that offers a list of specialized tools.
The Network Monito r is integrated into all of the system management packages offered by the service. The Network Monitor has two elements: a device monitoring tool and a traffic analyzer.
The network device monitor is based on SNMP. This strategy has the advantage of locating all of the devices on a network through a status report request. Any device out on the network will have an SNMP agent installed on it that listens for a request. SNMP agents send status reports in response to the Site24x7 request. The Site24x7 system involves an agent that is a data collector installed on the monitored system. This collects the SNMP responses and uploads them to the Site24x7 server over encrypted connections for processing.
The collection of responses tells the Site24x7 server exactly what devices are out there on the network and how they are connected. This is the autodiscovery feature in the system and it will replay every time an SNMP request broadcast is performed.
The responses from device agents get written up into a network inventory. The Site24x7 network monitor has a network topology mapper , which instantly creates a map of the network from the network inventory whenever it is accessed.
So, the topology map is always up to date. The other component of the Network Monitor is its traffic analyzer. This works through NetFlow and other device communication protocols to collect live traffic throughput data for each interface on switches and routers. This enables the Network monitor to enhance its device inventory and topology maps with live traffic throughput information per link. Instead, it forms part of each of the five monitoring service bundles that Site24x7 offers.
These are:. For example, taking out a subscription to Site24x7 Infrastructure gets you access to the Network Monitor plus server, virtualization, application, and website monitoring tools. You can get a day free trial of Site24x7 Infrastructure.
Syxsense Manage is a SaaS platform that enables the central administration of remote sites. The cloud-based console is accessed through any standard Web browser from anywhere. It is through this interface that the system manager enrolls a network. Getting a network included in the management system involves downloading an agent program onto one of the hosts connected to it. Once the agent is on site, it performs a network discovery routine. This service operates on a cycle, so it runs continuously throughout the Syxsense Manage service life.
This means that it will spot any changes to the list of devices connected to the network. The results of the network scan are shown in the system console. This lists all of the discovered devices.
Once the asset inventory is complete, the service scans each discovered endpoint and creates a software inventory. This operation will scan through devices running Windows , macOS , and Linux. The manager of multiple sites repeats these steps for all locations just by installing the agent on each site. With all sites enrolled, the manager can see an overview of the entire system and then focus in on each site and then down to each individual endpoint.
The software inventory can also be consolidated per site, which enables functions such as software license management. The package includes utilities for manual access and also automated maintenance services. Among the automated services is a patch manager. This maintains the software inventory and keeps checks on the suppliers of the operating systems and software packages listed in it, looking for the availability of updates.
When patches become available, the Syxsense Manager service copies them over to its own storage space. A Syxsense Manage package includes 50 GB of cloud storage. The Syxsense Manage package is a subscription service with the lowest bundle monitoring 10 devices. This is charged annually in advance.
You can assess the service with a day free trial. Paessler PRTG is a combined network device monitor, traffic analyzer, and server status manager. This will keep track of the health and performance of all of your network hardware and supporting devices. The server status monitoring extends to Cloud storage and online application services.
Application transaction and resource utilization are also covered, and the monitor extends to the tracking of database transactions that server application execution. PRTG will also cover virtual environments and wifi elements in your network. All of those different types of services take a lot of tracking, and it can be challenging to conceptualize all of the interfaces between different types of systems. The software installs itself, and one of the setup steps is a network discovery scanning phase that will document and list all of these different types of devices and how they work together.
You can opt for an online version of the system, but that still needs an agent to be installed on your system. The PRTG dashboard can assemble maps that represent all of the different elements of your network. You can access maps that show virtualization , wifi performance , VoIP traffic , general network performance by link and end-to-end , and connections over the internet through to the operations of network links and server performance owned and managed by other companies.
Any potential problems arising in any part of the system get reported to the console immediately. Those alerts can be customized , so you can specify your combination of errors and warnings that would make you sit up and take notice, rather than getting notified about low ink toner levels or other non-critical maintenance conditions.
While all of this monitoring is going on, the network discovery process keeps you in the loop. So, any outages or performance problems get reflected on your various network maps. The PRTG system can be accessed as a Cloud service , or it can be installed on premises — the software will run on Windows 10 and Server environments. The system is available for free to monitor small networks. Packet Monitor is available in-box via pktmon.
