A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

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

"Sometimes it took a month to troubleshoot something that we can now do within days."
"One of the valuable features is the packet decoding."
"The generation of KPI-like information that feeds to the nGeniusONE (management) server is the most valuable feature."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"Over the past three years, we've grown by about 200%, and the system has been able to manage that growth."
"Our support team are more responsive to failures and potential problems by using the Opsview Monitoring System."
"Opsview provides all the functionality of NetSaint and Nagios but with the simplicity of a GUI front end, using MySQL to centralize configuration."
"We use this solution for internal monitoring our own cloud platform because we are a public cloud provider, and we also use it for monitoring purposes on behalf of our clients."
"I like its scalability thanks to slaves, as you can add as many as you want, which also allows you to reach and monitor devices running on the network that are not accessible by the master."
"I am satisfied with the overall product since it works well…It is a stable solution."
"We now have a single view for all systems monitored within our IT estate, while we previously had three different systems (each configured differently)."
"The fully-extensible event handling has enabled us to reduce on-call incidents by more than 90%."
 

Cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"I would like to see improvements made to the user guide."
"I would say that this is not a scalable solution."
"The stability is okay, but sometimes we see that the memory on the server is not 100 percent correct and we need to stop and start the software to have it reallocated again."
"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."
"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."
"It's probably the priciest option of all its main competitors."
"The graphing feature needs work, although it has been rewritten in release 5.0 and we have yet to deploy it."
"We are starting to hit the limits of how we can scale out."
"Pricing and a few certain aspects in the solution needs to be improved."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"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."
