This post will explain PRTG Alternatives Our Top 6 Monitoring Tools. Developed by the German business Paessler AG, the Paessler Router Traffic Grapher, or PRTG, is a well-known network monitoring tool. IT was introduced about 15 years ago as an upgrade to MRTG, the first and most well-known network monitoring tool. After fifteen years, there are already too many network monitoring products on the market. Many of them rival PRTG in quality. Even better are some of them.

Additionally, there are some open-source and free solutions available that rival PRTG in terms of features and excellence. We’re looking at PRTG alternatives today. You’ve arrived to the right location if you’re using PRTG now and want something better, or if you’ve heard of it and want to know what else is out there. Here are the top six PRTG alternatives that we could identify.

We’ll define PRTG and highlight its key characteristics before going over the alternatives. That will undoubtedly make it easier for us to weigh our alternatives. We’ll also do our best to define and describe network monitoring for you if you’re unfamiliar with it. You should now include a better understanding of the characteristics of the products under review. We’ll also go through the advantages of network monitoring tools in general if you’re still not persuaded.

In this article, you can know about prtg alternatives here are the details below;

The six best PRTG alternatives that we could uncover will only be ready for review at that point. On our list, there is something for everyone with a mix of premium and free tools.

All of the products have intriguing features—some of them unique—that we’ll do our best to highlight, albeit none of them exactly match PRTG in terms of features.

What is PRTG, Exactly?

An agentless network monitoring system is what PRTG is, to put it briefly. It’s not necessary for any specialised software, known as an agent, to be operating on the systems being watched for agentless monitoring. Paessler Router Traffic Grapher is the acronym for PRTG, which is also a play on MRTG (the Multi Router Traffic Grapher), one of the original SNMP monitoring tools.

According to Paessler, PRTG has the quickest setup times of any monitoring product. It can be set up in a few minutes, claims the publisher. Due to its auto-discovery feature, which can scan your network for devices and add them to the tool automatically, it can take a little longer than two minutes to set up, but it’s still incredibly simple and quick. Following the conclusion of the auto-discovery, additional data about the discovered devices can be retrieved utilising a variety of communication protocols.

The system can interact via DICOM or the RESTful API in addition to using a combination of Ping, SNMP, WMI, NetFlow, jFlow, and sFlow. This tool is built using sensors that have been tailored for a particular need. There are HTTP and SMTP/POP3 (e-mail) application sensors, for instance. Additionally, there are sensors designed specifically for servers, switches, and routers.

PRTG offers more than 200 distinct preset sensors that can be utilized to gather data from the monitored devices, such as response times, processor, memory, database information, temperature, or system status. A variety of user interfaces are available from PRTG.

An Ajax-based web interface is the main one. Additionally, there are mobile apps for iOS & Android as well as a Windows corporate interface. The ability of the mobile apps to use push notifications for any alerts generated by PRTG is a good feature. There are also more conventional SMS or email notifications available. The server only functions on Windows, but any device with an Ajax-enabled browser can manage it.

Two versions of PRTG are accessible. There is a fully functional free version available, but it has a 100 sensor monitoring limit, with each monitored parameter counts as one sensor. For instance, monitoring two router interfaces counts as monitoring with two sensors. You must buy a licence if you want to use more than 100 sensors. 500 sensors cost $1600 as a starting point. A 30-day trial version that is fully functional, sensor-unlimited, and free is also available.

SNMP Monitoring Explained

The “S” in SNMP stands for “simple,” however the protocol is actually extremely complicated. However, you don’t need to be an expert in SNMP to use it, just like you don’t need to be an auto engineer to drive a car. It’s still beneficial to have a basic understanding of how it operates. SNMP is fundamentally a communication protocol that specifies how a management system for SNMP can read and write operational parameters in distant devices.

The terms for the parameters are OIDs, which stands for Object IDentifiers. The bytes out and bytes in counters are two OIDs that are particularly relevant when monitoring networking devices. As bytes are output or input, networking hardware automatically increments these counters. Each network interface has one such pair of counters. The SNMP protocol was created in an era before IT security became a concern. It only has little security as a result.

When connecting to a device that supports SNMP, an SNMP manager will send a “community string” along with the request. The request will be fulfilled if the string matches the one set up in the equipment. The two community strings that are generally present on devices are one for read-only OIDs and one for modifiable OIDs. Here is how a monitoring tool like PRTG employs SNMP to keep track of bandwidth usage.

The system periodically scans the interfaces’ bytes-in and-out counters at predetermined intervals. Devices are typically polled every five minutes. The monitoring system saves the retrieved values in a database or disc file of some kind. The remaining steps of the process only involve math. The number of bytes broadcast or received in five minutes is calculated by the monitoring system by subtracting the previous counter value from the current one.

The number can then be multiplied by eight to determine the number of bits, then it can be divided by 300 to determine the number of bits per second. Normally, this data is kept in a database and plotted on a graph to show how it has changed over time. The average use in bits per second over a five-minute period is what you receive out of this operation, which is a crucial point to keep in mind.

Imagine an interface of 100 Mbps. Even though the interface was at its maximum for half of the five minutes, the real traffic level could have fluctuated between 100 Mbps and 0 for 150 seconds in the five minutes between samples while still showing an average traffic of 50 Mbps. Each and every SNMP monitoring system has this flaw.

It won’t provide you with real-time, immediate utilisation data. Other methods can be used by some systems to obtain real-time traffic statistics, although they are uncommon. Most administrators’ needs can typically be met by five-minute averages.

Some Uses of Monitoring Tools

There are a number of situations when network monitoring tools like PRTG can be beneficial. It will first and foremost assist you in identifying points of dispute. Overused network circuits’ performance could and certainly will deteriorate. It goes without saying that you would want to prevent this.

Monitoring network bandwidth usage gives you the opportunity to see high usage—and address it—before it starts to impact consumers. Another significant benefit of network monitoring technologies is capacity planning.

It is common for network circuits, particularly long-distance WAN connections, to have a limited bandwidth that was deemed acceptable when they were first constructed.

But bandwidth requirements are constantly growing, much as disc storage.

You can determine which components of your network need to be improved and when by tracking the development of their bandwidth use.

When analysing bad application performance, network monitoring can be helpful.

If a user reports that a remote programme has slowed down, checking the network utilisation could help you determine whether or not network congestion is to blame.

If the network utilisation is modest, you should probably focus your troubleshooting efforts elsewhere.
