Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

User-friendly, stable, and scalable
The solution's automation has room for improvement. I have observed that Wireshark is much more commonly used for automation than OmniPeek. This is because when scripts are involved, Wireshark provides a great deal of flexibility for automating the process of packet sniffing. In the case of OmniPeek, its capabilities are limited, which restricts its automation potential. However, it is already user-friendly and compatible with Microsoft, so if it were to become comparable to Wireshark, it could potentially dominate the market. I have seen many new versions of OmniPeek, but I have never seen an automation version. The price of OmniPeek can be improved. Many customers have chosen the solution due to its user-friendly nature, but the cost often prevents them from making a purchase. This means that they may opt for an open-source tool instead. We should look into making the pricing more competitive and consider offering customization options to increase its utility in automation. This could be a game-changer.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"The solution is quite efficient."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"The most valuable feature of OmniPeek was the ability it gave us to see the connection procedure."
"The most valuable features are the voice bot, which checks the quality of service for voice, and the expert view that gives me insight on what and where to troubleshoot."
"It's a solid piece of software. It's stable."
"The most valuable feature of OmniPeek is the ability to assign custom color codes to the different packets easily."
"The most valuable feature is OmniPeek is user-friendly."
"OmniPeek's ability to convert application visibility into flow helps me quickly understand application performance over LAN, WAN, or wireless."
"I believe the most crucial feature of OmniPeek search is the ability to sniff packets based on channel switching."
 

Cons

"I believe Nagios Core will need to provide an option for big data platforms in the future."
"The interface could be improved."
"Nagios Core does not have a graphic display."
"It is a bit slow due to latency."
"The mapping is a little hard."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The dashboard and monitoring features could be improved."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"I don't see a clear roadmap in the future for improving this software."
"Making it more clear on how to configure the filters, or really automating them, would be an improvement."
"I would like to see the tool work in an open environment the same as how it does in a closed environment."
"The solution's automation has room for improvement."
"I am not using OmniPeek for automation, we only do manual testing. Automation testing is tedious to do. The automation should be more user-friendly. I have exposed some APIs but the usage is not user-friendly."
"I would like to see the saving feature improved. We have had issues if you do not save your progress then you have to start from the beginning."
 

Pricing and Cost Advice

"It's free."
"Nagios Core is a cheap solution."
"Lessening the price point would be an improvement."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"We are using the open-source, unpaid version."
"The solution is expensive."
"It's free."
"The product is cheaply priced."
"We have only purchased the add-on once and have not paid for any subsequent versions as it was too costly for us."
"The pricing for this solution could be improved, as it is a very expensive product."
"There are different types of licenses available."
