The Network Performance Monitoring module of Datadog adds on analytical functions to the Infrastructure package and includes capacity planning and troubleshooting utilities.

While the Infrastructure module looks at device statuses, the Network Performance Monitoring service examines traffic flows. The Datadog system uses agent software on-site, but all processing and data storage is implemented on the Datadog server. Systems administrators access the Network Performance Monitoring console through any browser in order to see live statistics on current traffic flows on the network.

Given that the service is based in the cloud, it can easily monitor remote networks, just as long as that network has the agent module installed on it. It also stores that information for analysis.

Administrators can trace the journey of a packet, view conversations between endpoints, segment traffic statistics per application or per origin or source, and identify the major bandwidth hogs on the network. The service can unify both onsite, cloud-based, and remote networks to give a complete picture of all network traffic generated by the business. The tool includes live network maps with traffic flows shown on them and it is also possible to see overloaded links or bottlenecks.

Datadog has a single plan level for its Network Performance Monitoring module. Charges are levied per host per month with a discount for paying annually in advance. The service is available for a day free trial. N-able RMM is a cloud-based remote monitoring and management software package. As this system monitors the network, it also stores metrics for analysis. Having access to all aspects of a system, including endpoints and servers, N-able has many channels of data for diagnostics and troubleshooting.

This is a data source for a wide range of diagnostic projects. The main value of these feeds lies in security. However, they also give insights into how to improve efficiency and avoid system management mistakes.

LOGICcards gathers data from 5,, endpoints on 4,, networks. Comparing the data extracted from these studies, the LOGICcard system analyzes a network and is able to point out factors and settings that are missing from that system, compared to the organization of the majority of other networks. Another LOGICcard service is a feed of warnings to look out for, such as patches that cause problems and should be held off or new internet-based scams.

A guidance aspect to this service also identifies errors to avoid in network configuration and tips on how to optimize bandwidth usage. Furthermore, the topics covered by a LOGICcard feed adapt according to your responses to past advice. The dashboard for N-able RMM is resident on the cloud.

N-able RMM is a subscription service. This is a great attraction for startups because there are no upfront costs for getting set up. There are no setup fees and there is no need to fork out for a software package Instead, the subscribing company pays a little each month. Interested potential customers can access a day free trial of N-able RMM. It can help you with troubleshooting because it can diagnose network issues right down the protocol stack and identify the root of the problem.

Port monitoring is one of the network diagnostics techniques that you can use with this tool. The PRTG system includes two port monitoring sensors. One homes in on a specified port on a particular device, the other will check a range of port numbers.

This tool only monitors TCP ports. The port range sensor has one extra feature that the single port sensor does not have. You can set it to check the port with TLS protection. Both sensors report on the response time of the port and whether it is open or closed.

PRTG includes network traffic analysis tools to help you troubleshoot delivery speeds. The tool includes a range of traffic monitoring techniques including route tracing to a destination with Traceroute and a Ping sweep , which will give you the response times to each node on your network. A packet-sniffing utility can tell you which applications and endpoints are producing excessive traffic and you can query the health of the network devices to see which are congested to the point of queuing.

Paessler built a tool that covers servers and applications as well as network statuses, port response times, and services to monitor all conditions that can cause software performance issues.

That monitoring is constant, so you will be able to trace back through events to spot the source of any performance issues. Paessler delivers PRTG as a cloud service or you can install the diagnostic software on your premises. The tool installs on Windows Server environments.

You can use the system for free for up to sensors. A successful ping confirms network connectivity between the two hosts and it also gives reports on packet loss. DNS is working on the local machine.

When you use a calculator, you can customize the output of the list of subnets. For example, you can vary the number and the size of subnets available in your network. A favorite subnet calculator among network admins and engineers is SolarWinds Advanced Subnet Calculator. It is free, easy-to-use, lightweight, and fully compatible with Windows OS.

Network admins use online speed tests to check the real bandwidth or throughput of an Internet connection. These tests are capable of measuring the time it takes to download or upload from the Internet to a specific host. Speedtest by Ookla is one of the most common.

It is free and can display download, upload speed, and latency information. The IT industry has taken Wireshark as the most important software for network troubleshooting, optimization, and security. The tool alone is downloaded over , times a month and is used anywhere, from home networks, SMBs, to large enterprises. Wireshark is a free and open source multiplatform network analyzer. It is the perfect tool for anyone that wants to monitor the security and performance of the network.

With Wireshark, you can analyze every packet exchange with a specific source and destination, and find faults in the communication process. NMap is one of the best network troubleshooting utilities because it cannot only discover a network but also enumerate any information, which can be useful for security penetration testing. When troubleshooting, NMap can help you test from your client computer to see if you have connectivity to open a TCP on a remote server. Nmap allows you to test and monitor a single host or multiple subnetworks at the same time.

To gather information, Nmap scans the ports in the network by sending raw packets. The tool waits and listens for responses and determines whether a port is open, closed or filtered by a firewall. They are either quickly available through the native command line interface or terminal of the OS, through the web browser, or in downloadable freeware. When you learn to use some or all of these tools effectively, you can reduce troubleshooting time exponentially, which means less wasted money and higher employee productivity.

Tools, such as ping, traceroute, ipconfig, netstat, nslookup, and Speedtest are easy to learn and extremely useful for any troubleshooting case. Subnet calculators might not be the right fit for critical troubleshooting phases, but can be useful for finding IP conflicts, overlapping subnets, or just for capacity planning. The last two tools, Wireshark and Nmap, are usually the favorite ones for experienced network professionals.

They are not available in the OS, or online; you have to download them.
