SolarWinds Network Performance Monitor (NPM) is an on-premises tool that empowers sysadmins to detect network and endpoint problems before they impact the user or company’s efficiency.

A key feature of SolarWinds NPM is its flexibility to scan networks and detect new devices. This can be done through a simple SNMP agent, packet sniffing interface, WMI, or ICMP protocol. This range of options can allow admins to enable read-write access to the agent, giving them the option to push out configuration changes and commands through the NPM dashboard itself.

NPM does a great job of balancing real-time alerting with additional network performance health and insights. SolarWinds NPM automatically prioritizes critical issues such as hardware failure and network communications problems to the top of the queue, so admins know what needs to be tackled first.

Real-time metrics and performance benchmarks can easily be pulled and compared to historical baselines to allow for quick comparisons without having to draft lengthy reports. With so many devices and data points to track across a network, NPM works to consolidate and simplify only the most important metrics through a single dashboard.

Outside of dashboards and reporting, SolarWinds NPM has a suite of visualization tools like topological maps that make seeing different traffic routes and the devices they pass through easily. These maps are fully customizable and live, meaning you can select a node to see real-time statistics and push changes directly to them.

This balance between proactive and reactive alerting paired with the tool’s ease of use and flexibility is why it’s number one on our list. You can test out SolarWinds Network Performance Monitor free for a full 30 days.

5. Site24x7 Infrastructure Monitoring (FREE TRIAL)

Site24x7 Network Map

Site24x7 Infrastructure Monitoring is a plan that is offered by the Site24x7 cloud platform. The package includes network, server, cloud platform, middleware, application, and website monitoring and it also provides log management.

The package needs a link to the monitored locations. This is implemented by installing an agent on site and on cloud platforms. The agent is available for Windows Server and Linux. Once the agent is operating, it provides a device discovery process that creates a network inventory. The network search repeats constantly and if any hardware is added or removed, those changes are reflected in an updated inventory. Site24x7 draws up a network topology map based on the data held in the inventory.

The discovery process is based on the Simple Network Management Protocol (SNMP) as this process repeats, the service gathers status reports from each network device. This data is uploaded to the Site24x7 server where it is compiled into live performance graphs. The tool also compiles traffic activity data to track the performance of connections on the network and across the internet to other sites and cloud platforms. The statistics that Site24x7 calculates from this information is important for tracking the quality of service of VoIP connections.

Alongside its network monitoring routines, Site24x7 performs server monitoring, which tracks physical resource availability and activity. The tool also tracks the activity of logical servers, such as Web servers and email servers. You can use the tool to track virtualizations as well.

The package includes log management and network configuration management but these two units are the full extent of the system management tools in the bundle. This is primarily a monitoring package.

The core system monitoring package can be extended by integrations, These are plug-ins that provide monitoring capabilities for specific technologies and products, such as database management systems and containers.

All of the modules in the platform include performance thresholds that, when crossed, will generate alerts. Those alerts appear in the system console and they can also be sent as notifications to technicians by email or SMS.

The Infrastructure edition of Site24x7 is sized to be suitable for use by small businesses. Larger businesses can get capacity extensions by paying a higher subscription rate.

Datadog offers deep insight into device and network infrastructure by combining visual aesthetics with power automation to help reduce emergencies and put admins in a more proactive position.

Provided as a cloud service, Datadog uses a simple network monitor to pull raw data into their network, and output that information into actionable insights, historical metrics, and prioritized alerts. The platform supports both cloud and multi-cloud environments as well as IoT deployments and hybrid network setups.

On top of this flexibility, the platform has a robust network of partners, currently supporting integrations into 500 other tools, software, and platforms. From an organizational perspective keeping assets straight in Datadog is easy with a number of prebuilt and customizable filtering features. For instance, you can create and classify your own groups of networks or devices through internal tagging which can be used to quickly search across a range of devices.

Unlike some tools, there is no complicated query language to master, or proprietary coding to learn when searching for insights and performance data. Much of the search-based functions in Datadog are object-based or highly visual in nature, meaning even junior administrators can dive into the platform without getting overwhelmed.

Machine-based learning plays a large role in why Datadog is a powerful infrastructure management tool. Artificial intelligence helps reduce noisy and repetitive alerts by suppressing them and displays to the surface only critical notifications humans need to review. When pairing Datadog with automation you can put a serious dent in your workload.

For instance, if you create a workflow rule that fires off a cleanup script or moves certain folders if an Exchange backpressure alert occurs through Datadog. This not only helps keep the server online but positions you to look for more big picture solutions, rather than running to put out another fire.

Datadog offers transparent pricing across three tiers and has a free version of infrastructure monitoring that is limited in hosts and features. You can try the full version of Datadog Infrastructure monitoring free for 14 days.

7. Dynatrace

Dynatrace leverages AI and sleek design to help give deep insight into network infrastructure automatically. Dynatrace can provide visibility into multi-cloud, PaaS environments as well as tailored metrics into virtual and physical server architectures.

By working directly with artificial intelligence assistance tools, administrators can continuously monitor the entirety of the network to detect anomalies, identify faulty hardware, and prioritize incoming events for admins for NOC team members.

Data is pulled from both event logs as well as sniffed live across the network and pulled directly into the Dynatrace system. This can be both processed and visualized as well as interpreted by machine learning algorithms to apply automatic remediation.

Dynatrace arguably has some of the best-looking dashboards available of all the monitoring tools. These can help “silo” different widgets into categories like quick overviews, cloud health, and local infrastructure status. Underneath it all full-stack monitoring gets to work analyzing dependencies and providing root cause analysis to help complete tickets faster and prevent infrastructure issues from impacting the bottom line.

All real-time alerts and metrics generated in Dynatrace can be ported over to multiple supported ITSMs like ServiceNow to automatically create and prioritize tickets for the NOC team. Alternatively, these same integrations can be used to automatically trigger scripts, or kick off a workflow.

Infrastructure monitoring with Dynatrace currently starts at $21.00 per month when billed annually, and allocated up to 8 GB per host. You can test the platform out yourself through a free 15-day trial.
