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.
Jeff Cronstrom - PeerSpot reviewer
A highly stable solution that can be used to monitor system availability
The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup. You can clone that service, and it allows you to add new services quickly. You can bring up new servers, and you can easily add them. Also, there's an API to be able to add services as well. We don't use the API. We mostly use the cloning function because it stores everything in a back-end database. The underlying monitoring platform for our version is Nagios. That's where we upgraded from Nagios to Opsview.

Quotes from Members

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

Pros

"The reporting structure and the feature set are valuable to me."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"The good thing about Nagios Core is it covers everything."
"The application performance monitoring feature is valuable."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"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."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"I would rate the overall solution ten points out of ten."
"I am satisfied with the overall product since it works well…It is a stable solution."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider. We also use it for monitoring purposes on behalf of our clients."
"The most valuable feature of Opsview is the ability to clone the services when you're monitoring something out of the test setup."
"What was very compelling about OpsView was that we could dial out the noise and have meaningful and actionable alerts."
"It's a good solution. It covers all aspects of monitoring purposes."
 

Cons

"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"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 would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"I would like to see more training videos."
"The core version is no match for the XI version."
"The scalability needs improvement, it's not scalable at this time."
"The dashboard should be improved."
"The alerting mechanism in Nagios Core could be improved."
"In a future release, we would like to have Observ for AI. Any AI and intelligence it can add to the monitoring is obviously beneficial. We would also like to have automated callouts."
"Customized reporting can be improved."
"Some of the graphics on Opsview could be improved."
"Pricing and a few certain aspects in the solution needs to be improved."
"Maybe the graphical representation can be improved. It can be enhanced for better visualization. It could be a little better. And the graph center can be improved."
 

Pricing and Cost Advice

"It's free."
"The solution is expensive."
"Nagios Core is a cheap solution."
"It's free."
"We are using the open-source, unpaid version."
"Most the plugin features are free."
"We are using the free version."
"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."
"I would rate pricing a seven out of ten, where ten is the highest price."
"The solution is priced similarly to other tools offering similar features."
"The solution is not cheap. I think that the pricing is a little bit on the high side."
