PRTG provides for efficient and centralized Syslog message management. It collects Syslog messages according to origin and severity, as well as time and IP address. With PRTG, you can seek out weak spots and take action at once. Syslog stands for System Logging Protocol and is a standard protocol used to send system log or event messages to a specific server, called a syslog server. It is primarily used to collect various device logs from several different machines in a central location for monitoring and review.
The protocol is enabled on most network equipment such as routers, switches, firewalls, and even some printers and scanners.
In addition, syslog is available on Unix and Linux based systems and many web servers including Apache. PRTG is comprehensive network monitoring software. Still not convinced?

Datadog offers two network monitoring tools, one of these is the Network Device Monitoring system and the other is the Network Performance Monitoring.
While the Network Performance Monitoring system looks at bandwidth usage, the Network Performance Monitoring module uses SNMP to extract traffic data from switches and routers along with device health reports. Thanks to SNMP, the monitor is able to discover all of the devices on the network. This enables the tool to compile a network asset inventory. That list of devices provides an index through to the report from each piece of equipment. The total list provides a quick overview of all assets, showing color-coded statuses.
The device polling by Datadog is repetitive. That means the system will spot whenever a device is added or removed from the network. Each scan of the network refreshes the asset inventory, so your view of all equipment is always up to date. It is also possible to set up performance thresholds on any of the statistics that the monitor gathers. If one of those thresholds gets crossed, the system will generate an alert.
Alerts from the Network Device Monitoring service can be forwarded to key staff as notifications by email or through Slack, PagerDuty, Jira, or Webhooks. The alerting mechanism means that you can leave the Datadog system unattended and it will watch over performance.
You will be brought back to the monitor if any problems arise. The ability to see the statuses of all of your network devices in one screen makes it very easy to spot performance problems and know exactly where they are. Datadog offers a menu of modules and while each will work individually, they provide enhanced system monitoring capabilities when combined. For example, using both the Network Performance Monitoring and Network Device Monitoring modules together gives you a complete view of network activity and performance.
The Network Device Monitoring system is based in the cloud and reaches out to monitored networks through the installation of agents. It is possible to monitor any site anywhere with this tool and even cover multiple sites in the same account. You can get a look at the Network Device Monitor by accessing a day free trial. The tool watches over device health and also extracts traffic data from switches and routers.
Repetitive polling ensures that the automatically generated device asset inventory is always kept up to date. The monitor processes SNMP Trap messages into alerts so that you know immediately when a device is experiencing problems. The installation of this system is straightforward, thanks to a device discovery tool, which will locate, map, and configure all of the nodes on your network, installing agent software, or instructing existing, pre-loaded agents.
The console of this network monitoring system tracks availability and load and keeps you updated when new devices are added or nodes get taken away. A graphical map shows you all of the topologies of your network and reports on link utilization through color-coding. The SolarWinds console can zoom in on each detected device and show a detailed performance report. The Node Details screen of the console leverages graphical displays to make visual checks on the health of a device instantly.
A typical network includes SNMP-enabled devices sourced from several different manufacturers. SolarWinds is ideal for a multi-vendor network environment because it relies on the universal Simple Network Management Protocol to ensure interoperability. This enables cloud services to be integrated into the network. The performance of links to those off-premises services can help the network manager decide where extra resources are needed to prevent bottlenecks.
The automation of setup and the ability to use the Network Performance Monitor to adjust the settings of devices means that the Network Manager can maintain multi-site networks from anywhere in the world. It is no longer necessary to employ a key network manager at every site of a network because all administration tasks can be centralized.
SolarWinds offer a day free trial. The monitor and intuitive dashboard give you a commanding view of network resources and performance including device event information.
Atera integrates its network monitoring system into a complete MSP support package, which includes a Help Desk system.
The complete system covers the usage and capacity of apps and infrastructure and generates invoices and reports from logs of staff activities. This option would be the right choice if your IT department operates as an income center or if your business provides fee-based support to other companies. The SNMP involvement in this package is concentrated on the network monitoring module. SNMP Traps provide a vital element of the monitoring system, providing real-time alerts in the Atera console.
The network manager dashboard includes scripts that automate routine administration tasks, and you can also create your own custom scripts to complete your regular tasks your way. Atera allows you to reach out from the data center, and even leave it. The system includes remote access procedures and it is also possible to access the dashboard from a mobile device. The dashboard includes real-time performance graphs to speed decision making.

ManageEngine OpManager is a very comprehensive facilities management tool that includes network mapping, configuration management, traffic analysis, WAN link monitoring, network status monitoring, and even a specific module for VoIP traffic management.
The first day of an OpManager install involves network discovery and mapping, which the management software can carry out automatically. The system uses a range of protocols to keep track of the performance of equipment and infrastructure. Monitoring data can be accessed from mobile devices, which helps you keep on top of situations when you are out of the office or on a site visit. Overall, the management console is beautiful.
Topology visualizations are map-based for multi-site networks, and colorful graphs and dials make quick overview checks fruitful. The Configuration Management module helps you keep track of software version statuses and enables you to patch and update remotely from one central location. You can analyze traffic by application and get network load visualizations that show overloaded or underutilized infrastructure at a glance.
These facilities extend into security management because you can get alerts on exception traffic levels from certain devices, specified applications, or both. This demonstrates where unusual activity occurs, and traffic analysis tools can help you packet sniff problems to identify irregular system usage. The Trap processing element of OpManager can process messages per second, giving collated feedback on arising equipment problems and failures.
Logging functions include trap conditions. Other logs are an event log for security purposes and Syslog interpretation that highlights critical conditions in all system logs. The visibility of network performance is made easier by monitoring templates, which are pre-written reports that source live data from the entire monitoring system.
The free edition can monitor up to 3 devices. You can download OpManager on a day free trial. The other two are packet sniffing and NetFlow. Each of these three technologies provides a specific level of network information. NetFlow and packet sniffing are both engaged when analysis of network traffic is required. The interpretation of SNMP messages is complicated by the fact that there are several different versions of the standard. The network management software you choose might not be compatible with the SNMP versions that firmware of your equipment uses.
Paessler has also compiled interpretations of the custom OIDs that many network equipment manufacturers add to the standard MIB list. In all, PRTG incorporates more than sensors, giving you the ability to keep track of network performance over a wide range of factors.
However, you might need to access each device individually and manually set up SNMP , because many devices are shipped with their SNMP capabilities switched off.
Equipment firmware that includes firewalls also has to be adjusted to allow SNMP messaging through. The management console includes an SNMP tester, which enables you to get more precise details remotely on a reported alert condition arriving via a trap message. The dashboard of PRTG includes graphical elements, such as dials and graphs that give instant recognition to overall network performance.
It is also possible to drill down and examine the status reports of each device, which can also be displayed as real-time graphs. Download a day free trial here. SNMP reporting capabilities are built into all network devices. The typical report only gets sent out when a request from an SNMP manager is received by the device agent.
However, trap messages get sent out without a request. In this respect, SNMP traps are a form of log message. This is an easy task that just requires the Log Analyzer to listen on the network. The tool is able to process up to live trap messages per second. The tool displays trap messages in its console as each arrives. These messages get filed as any log message would be.
While processing the trap, the Log Analyzer uses the alerting system of the SolarWinds Orion platform to send out notifications. The alerting system needs to be set up and it can send emails or SMS messages to any address or number entered into the profile interface. Traps can be sorted and filtered to identify patterns of behavior.
SolarWinds offers the tool on a day free trial. This tool support IT departments in their task of managing several remote sites from one central location. The network monitoring part of this system management bundle is based on SNMP. It broadcasts status requests at regular intervals and receives back the MIB responses from device agents.
Those responses get quickly interpreted into live performance data shown on the screen. The responses to the first report request enable SolarWinds RMM to assemble a full network inventory. This list of devices is always checked whenever each successive status poll result comes in, so devices are added or removed from the list accordingly, creating a live update to the network inventory.
When the remote monitoring and management software receives a trap message, it generates an alert, which is shown on the dashboard. This alert can also be sent out to key staff as an email or SMS message. Alerts can be customized or downgraded through the settings of the RMM. For example, the network manager can set up a custom alert based on a combination of inputs.
As well as alerts, the N-able RMM receives warning statuses, which are less severe. A combination of warnings can be specified as an alert condition.
Unlike many network monitoring tools, N-able RMM includes an automation manager. This is an easy-to-use drag-and-drop interface that enables network managers to set actions that can be triggered by alerts. The automation manager is also available to set up routine maintenance tasks on a schedule.
N-able RMM is a very cost-effect solution because it frees up IT professionals from mundane tasks and makes them available for more important work.
The service costs nothing to implement because it is charged for by subscription and includes all supporting software and hardware. N-able RMM is available on a day free trial. Site24x7 is a cloud-based service, which probably points towards the common format of the future for infrastructure monitoring systems — the network monitoring software does not need to be resident on a server that is directly connected to that network. Many business managers may be nervous about network information being let outside the building, particularly in these days of heightened cybersecurity attacks.
An essential element for any business service delivered remotely is connection security. Site24x7 addresses these concerns by encryption communication between their servers and the networks of their customers. Another potential security weakness lies in the communication between technicians at the client site and the console resident on the Site24x7 server. NET 4 … er base ranging from enterprises, equipment vendors, and service providers, AdventNet has emerged as a very affordable and high-quality alternative to expensive software that is common in this industry.
