Nishith-Vyas - PeerSpot reviewer
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.
Vinal-Patel - PeerSpot reviewer
Real-time analytics and alerts improve application performance and network operations
OmniPeek's ability to convert application visibility into flow helps me quickly understand application performance over LAN, WAN, or wireless. Its real-time analytics, integrated with LiveNX ( /products/liveaction-livenx-reviews ), allow me to monitor business-critical applications and set up alerts for application performance issues. This centralized dashboard and alert system is highly valuable for maintaining network operations.

Quotes from Members

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

Pros

"Nagios Core is very configurable. Whatever you want, you can do it."
"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."
"Nagios Core is stable."
"I would rate the overall solution ten points out of ten."
"Provides timely notifications."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"The good thing about Nagios Core is it covers everything."
"The most valuable feature of OmniPeek is the ability to assign custom color codes to the different packets easily."
"It's a solid piece of software. It's stable."
"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."
"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."
"The most valuable feature is OmniPeek is user-friendly."
"The most valuable feature of OmniPeek was the ability it gave us to see the connection procedure."
 

Cons

"The core version is no match for the XI version."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"I would like to see more training videos."
"The scalability needs improvement, it's not scalable at this time."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"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."
"The solution's automation has room for improvement."
"OmniPeek doesn't support Linux or Unix installations, which prompted the shift to Wireshark."
"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."
"I would like to see the tool work in an open environment the same as how it does in a closed environment."
"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."
 

Pricing and Cost Advice

"We are using the free version."
"Lessening the price point would be an improvement."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is an open source solution, and there are no licensing fees."
"Nagios Core is free to use."
"Nagios Core is a cheap solution."
"The product is cheaply priced."
"We are using the open-source, unpaid version."
"There are different types of licenses available."
"The pricing for this solution could be improved, as it is a very expensive product."
"We have only purchased the add-on once and have not paid for any subsequent versions as it was too costly for us."
