Here are 20 of the best free tools for monitoring devices, services, ports or protocols and analyzing traffic on your network. This list is intended to supplement 101 Free SysAdmin Tools. Even if you may have heard of some of these tools before, I’m confident that you’ll find a gem or two amongst this list.

1. GFI LanGuard (our award-winning paid solution)

People say it’s good to be modest and not to brag, but we’re so proud of our network management tool that we had to start the list with GFI LanGuard. You can use it to scan both small and large networks, in search of software vulnerabilities and unpatched or unlicensed applications. Information coming from up to 60,000 devices, running on Windows, Mac OS or Linux, will be shown in a centralized web console, so you’ll be able to see the state of your whole network at any moment and from any location.

With centralized patch management and network auditing, GFI LanGuard prevents potential compliance issues, but if you’re a sysadmin the fact that all machines are patched and secured will surely seem like a more important advantage. But, don’t take our word for it, download the free 30-day trial and try it out.

2. Microsoft Message Analyzer

Microsoft Message Analyzer, the successor to Microsoft Network Monitor 3.4, has an intuitive and flexible UI with effective filtering options that allow you to break down and drill into captured packets (or ‘messages’ as they are called in Message Analyzer). By adding ‘Color Rules’ to different protocol traffic, you can make scanning through areas of interest easier and faster.

Some of its highlighted features include automated data capture (using PowerShell cmdlets to start or stop traces based on a particular trigger), TLS/SSL decryption support and customizable filter expressions.

Microsoft Message Analyzer allows you to assess multiple log data sources from a single pane of glass. You can capture, view and analyze network protocol traffic side-by-side with other system or application events (e.g., Event Logs or SQL Tables), making it a valuable addition to your network toolkit.

When you launch Microsoft Message Analyzer, click ‘Start Local Trace’ to immediately start capturing traffic from the local machine, or ‘New Session’ to add a Data Source to capture.

3. Nagios

Nagios is a powerful network monitoring tool that helps you to ensure that your critical systems, applications, and services are always up and running. It provides features such as alerting, event handling, and reporting. Nagios Core is the heart of the application that contains the core monitoring engine and a basic web UI. On top of Nagios Core, you can implement plugins that will allow you to monitor services, applications, and metrics, a chosen frontend as well as add-ons for data visualization, graphs, load distribution, and MySQL database support, amongst others.

Once you’ve installed and configured Nagios, launch the Web UI and begin to configure host groups and service groups. Once Nagios has had some time to monitor the status of the specified hosts and services, it can start to paint a picture of what the health of your systems look like.

4. OpenNMS

OpenNMS is an open source enterprise-grade network management application that offers automated discovery, event and notification management, performance measurement, and service assurance features. OpenNMS includes a client app for the iPhone, iPad or iPod Touch for on-the-go access, giving you the ability to view outages, nodes, alarms and add an interface to monitor.

Once you successfully login to the OpenNMS web UI, use the dashboard to get a quick ‘snapshot view’ of any outages, alarms or notifications. You can drill down and get more information about any of these sections from the Status drop-down menu. The Reports section allows you to generate reports to send by e-mail or download as a PDF.

5. Advanced IP Scanner

Advanced IP Scanner is a fast and easy to use network scanner that detects any network devices (including wireless devices such as mobile phones, printers, and WIFI routers) on your network. It allows you to connect to common services such as HTTP, FTP and shared folders if they are enabled on the remote machine. You are also able to wake up and shut down remote computers.

The installer allows you to fully install the application on your machine or run the portable version. When you launch Advanced IP Scanner, start by going to Settings > Options to select which resources to scan and how fast/accurate you want the results. You can then choose which subnet to scan and proceed with pressing the “Scan” button. Once the scan is complete, expand the results to see which resources you can connect to for each discovered device or export your results to XML/HTML/CSV.

6. Capsa Free

Capsa Free is a network analyzer that allows you to monitor network traffic, troubleshoot network issues and analyze packets. Features include support for over 300 network protocols (including the ability to create and customize protocols), MSN and Yahoo Messenger filters, email monitor and auto-save, and customizable reports and dashboards.

When you launch Capsa, choose the adapter you want it to bind to and click “Start” to initiate the capture process. Use the tabs in the main window to view the dashboard, a summary of the traffic statistics, the TCP/UDP conversations, as well as packet analysis.

7. Telerik Fiddler

Fiddler is a web debugging tool that captures HTTP traffic between chosen computers and the Internet. It allows you to analyze incoming and outgoing data to monitor and modify requests and responses before they hit the browser. Fiddler gives you extremely detailed information about HTTP traffic and can be used for testing the performance of your websites or security testing of your web applications (e.g., Fiddler can decrypt HTTPS traffic).

When you launch Fiddler, HTTP traffic will start to be captured automatically. To toggle traffic capturing, hit F12. You can choose which processes you wish to capture HTTP traffic for by clicking on “All Processes” in the bottom status bar, or by dragging the “Any Process” icon from the top menu bar onto an open application.

8. NetworkMiner

NetworkMiner captures network packets and then parses the data to extract files and images, helping you to reconstruct events that a user has taken on the network – it can also do this by parsing a pre-captured PCAP file. You can enter keywords which will be highlighted as network packets are being captured. NetworkMiner is classed as a Network Forensic Analysis Tool (NFAT) that can obtain information such as hostname, operating system and open ports from hosts.

In the example above, I set NetworkMiner to capture packets, opened a web browser and searched for “soccer” as a keyword on Google Images. The images displayed in the Images tab are what I saw during my browser session.

When you load NetworkMiner, choose a network adapter to bind to and hit the “Start” button to initiate the packet capture process.

9. Pandora FMS

Pandora FMS is a performance monitoring, network monitoring, and availability management tool that keeps an eye on servers, applications and communications. It has an advanced event correlation system that allows you to create alerts based on events from different sources and notify administrators before an issue escalates.

When you login to the Pandora FMS Web UI, start by going to the ‘Agent detail’ and ‘Services’ node from the left-hand navigation pane. From here, you can configure monitoring agents and services.

10. Zenoss Core

Zenoss Core is a powerful open source IT monitoring platform that monitors applications, servers, storage, networking, and virtualization to provide availability and performance statistics. It also has a high-performance event handling system and an advanced notification system.

Once you login to Zenoss Core Web UI for the first time, you are presented with a two-step wizard that asks you to create user accounts and add your first few devices/hosts to monitor. You are then taken directly to the Dashboard tab. Use the Dashboard, Events, Infrastructure, Reports and Advanced tabs to configure Zenoss Core and review reports and events that need attention.

11. PRTG Network Monitor Freeware

PRTG Network Monitor monitors network availability and network usage using a variety of protocols including SNMP, Netflow, and WMI. It is a powerful tool that offers an easy to use web-based interface and apps for iOS and Android. Amongst others, PRTG Network Monitor’s key features include:

Note: The Freeware version of PRTG Network Monitor is limited to 100 sensors.

When you launch PRTG Network Monitor, head straight to the configuration wizard to get started. This wizard will run you through the main configuration settings required to get the application up and running, including the adding of servers to monitors and which sensors to use.

12. MiTeC Network Scanner

MiTeC Network Scanner is a modest yet feature rich network scanner for detecting network devices which include remote command execution and shutdown functionality, as well as Active Directory scanning and a bunch of in-built network tools as some of its key features.

When you launch MiTeC Network Scanner, start by selecting one of the scans to run from the Scan section on the top ribbon.

13. Splunk

Splunk is a data collection and analysis platform that allows you to monitor, gather and analyze data from different sources on your network (e.g., event logs, devices, services, TCP/UDP traffic, etc.). You can set up alerts to notify you when something is wrong or use Splunk’s extensive search, reporting, and dashboard features to make the most of the collected data.
