Here’s the Best Nagios Alternatives for Network Monitoring in 2023:
SolarWinds Network Performance Monitor (NPM) is a tool that makes the life of a network administrator much easier. It is able to monitor and alert you about any issues or problems on your network, with very little delay. You are able to monitor many different objects and sources such as applications, services, VPN tunnels, and much more.
It features Network Availability Monitoring, Critical Path Visualization, Intelligent Mapping, Performance Analysis and Advanced Alerting. This means that you can configure it and set it up to match your requirements. For instance, you can configure it as a Cisco Network Monitoring Tool.
This will give you the ability to monitor and analyze faults, availability and the performance of the Cisco device itself.
You can also use this application as a Cloud Server Monitor. Because of the remote nature of Cloud services and infrastructure it can be challenging to see if everything is running as it should be. For this reason, SolarWinds NPM allows you to Visualize the full network path of the device from the device itself all the way to its end point.
This is achieved with cloud monitoring by NetPath.
Other important features that this product offers includes Deep Packet inspection and analysis.
This allows you to gain greater knowledge about the current state of your network, as well as the state of traffic and data flow.
If you would like to try it out for yourself then you can find the details on how to download a free trial. All you need to do is give them your details and they will email you a link so that you can download and test it out for yourself.

Site24x7 is a cloud platform that offers a range of system monitoring tools. Those different monitors are bundled together into packages that offer server, network, and application monitoring. The Site24x7 system has integrations, which are similar to the plug-ins of Nagios and extend the capabilities of the system to enable it to monitor specific products.
As well as monitoring physical infrastructure, the Site24x7 package is able to supervise virtual assets, such as VMs and containers. This includes VMWare, Hyper-V, Nutanix, Docker, and Kubernetes systems.
The Site24x7 package is delivered from the cloud and it can also monitor other cloud systems, such as AWS, Azure, and Google Cloud Platform. The system also has the capabilities of monitoring Web applications through real user monitoring and synthetic monitoring tools.
On site, the tool will track the performance of networks by querying network devices through SNMP. This gives you a live report on all switches, routers, and firewalls. The data from SNMP queries also enables the Site24x7 system to compile a network inventory and a network topology map.
The system can access traffic information from those devices, too, plus wireless APs. This traffic monitoring is carried out through NetFlow, J-Flow, sFlow, IPFIX, AppFlow, and NetStream.
On-site servers running Windows and Linux are also covered by the Site24x7 monitor. All of the device metrics gathered by the Site24x7 collector can have performance thresholds placed on them. These warn of capacity issues and can be forwarded as notifications by SMS, email, push notification, voice calls, and RSS feeds.
Pricing: Prices start from $9 per month, charged annually.

Zabbix is an enterprise grade software package that is designed to give you a better picture of your network. It collects metrics for all the devices on your network like devices and systems, as well as applications. Zabbix is designed to collect metrics about many different items within your network. It does this via SNMP and IPMI agents, and it uses an agentless system for monitoring user services.
Problem detection is taken care of via smart thresholds that you define for yourself. This means that you can decide which services need the highest priority response from you. This is important for most people because mission critical systems need to be prioritized above normal user devices, as an example.
Pricing: Zabbix is free and open source, but there are costs for support.
