A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…

Real-time dashboards have improved our deployment monitoring and incident response
We are using Opsview ourselves, rather than being a consultant or a reseller. We do not use its auto-discovery feature. We do not utilize its API driven architecture. I do not know what metrics we use to assess the effectiveness of Opsview's hybrid IT monitoring. Overall, I am pretty satisfied with Opsview as it is good for what it does. I do not know if Grafana has any other advantages besides better stats, as I am not involved in that side. Based on my experience, I would still recommend Opsview to others as it is good for what it does. I gave this review a rating of 8.

Quotes from Members

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

Pros

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
"I am satisfied with the overall product since it works well…It is a stable solution."
"Afterwards, they were impressed by how easy monitoring could be, and they no longer had to edit large text files in order to configure hosts and service checks."
"Our support team are more responsive to failures and potential problems by using the Opsview Monitoring System."
"Overall, I am pretty satisfied with Opsview as it is good for what it does."
"The multi-tenancy that's available through this is one of the most valuable things."
"Excellent customer support from Cerner."
"With the monitoring capabilities, I can tell when things happen and be proactive about them instead of constantly putting out fires."
"Over the past three years, we've grown by about 200%, and the system has been able to manage that growth."
 

Cons

"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"The graphing feature needs work, although it has been rewritten in release 5.0 and we have yet to deploy it."
"It can be a little bit flaky with the agent on VMware."
"Sometimes Opsview has crashed, but the multiple master/slave solution provides consistent uptime for monitoring."
"Large Opsview setups come with high licensing fees."
"In Opsview 4.6.3, there is no provision for making bulk changes to monitored servers via the GUI, though it is possible to custom-script bulk changes via the API."
"Often the webpage becomes inaccessible and you need to refresh the page."
"Pricing and a few certain aspects in the solution needs to be improved."
"There is always room for improvement, and part of the reason we're looking at Grafana is because there are things it can do that Opsview cannot do as well."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"The solution is priced similarly to other tools offering similar features."
"I would rate pricing a seven out of ten, where ten is the highest price."
"The solution is not cheap. I think that the pricing is a little bit on the high side."
