Nagios is a great tool for Server and Application monitoring and keeping an eye on your infrastructure and organization. For being Open Source and widely available for multiple operating systems, Nagios can sometimes have its limitations compared to other commercially available options.
We'll discuss some of the best Nagios Alternatives for server and network monitoring for your infrastructure, along with some in-place replacements that make it seamless to migrate.
Common issues that have arisen from folks using Nagios are things such as Auto-discovery of services and applications being used without additional configuration and add-on's being thrown into the mix.
Gartner even had an article on the matter than went into some detail about why folks should get rid of it altogether and look for a better supported software, in case your “talented engineer” decides to leave the company, you won't have a mess on your hands trying to figure out how to upgrade and config a Nagios instance.
Regardless of why your looking for an alternative to Nagios, we've detailed a list of the best network monitoring software that can replace Nagios in your environment. Some of these are Free, others are Paid and commercially supported, which we Highly recommend in any production environment. We've been in many situations where having a support contract has saved us hours on end in troubleshooting and misconfiguration of the software.

PRTG is another fairly familiar software package in the server and application monitoring world with its flexible offerings in terms of capabilities and functionality. PRTG has a nice graphical user interface and is fairly easy to use when it comes to getting setup and moving fairly quickly.
PRTG Does Not have the Nagios script Import feature that Solarwinds has but has a nice Template system and Auto Discovery system that will allow you to setup devices in an easy manner.
Some Main features of PRTG:
- Customizable and Flexible interface
- Flexible Alerting System
- Distributed Monitoring Capability

PRTG contends nicely with the others from above, but as mentioned above, lacks the native functionality to import Nagios scripts into the Program. Check out more about PRTG at their official site and learn about their full Feature Set there.
3. ManageEngine OpManager
Opmanager is another choice for switching out an open-source software and moving to a commercial grade software. As we've mentioned about in the Solarwinds description, one of the main issues we have is getting proper support and not having to install several other applications in order to do the job of what 1 installation should do.
ManageEngine has the following features:
- Network & Server monitoring capabilites
- Bandwidth usage and analysis
- Firewall event log management
- and Much more
We did not see anything on their Site in regards to importing Nagios scripts and this could prove to be cumbersome when trying to migrate over. Solarwinds still has the advantage over Opmanager in this regards, but if you would like to read a detailed review of ManageEngine Opmanager, you can see it Here!

Some of the Main features include:
- Automated Discovery

- VM Overviews and Monitoring capabilites
- Application & Server Performance Monitoring
We dug around to see if we could find some information in regards to importing or converting existing Nagios scripts into WhatsUp Gold, but could not find anything on this package either.
