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…

Quotes from Members

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

Pros

"Its event management capabilities are very open and flexible. I haven't seen a use case scenario with a customer that we couldn't actually solve the problem for, so it's really good. There are some interesting things that happen in an enterprise network (things that people don't normally expect), and the event management product is very flexible. You can solve problems as far as your imagination can go with it."
"Having a good monitoring implementation has made a world of difference to our operations teams."
"The tool is flexible enough to be customized based on customer requirements."
"Now, through the use of this product, we have been able to reduce the headcount by five people, as we are able to eliminate the eyes on the glass."
"It's a really good tool and most of the issues we've got, they've either fixed or they're fixing to fix."
"BMC TrueSight Operations Management can be used to monitor anything on-premises, including the server, applications, log monitoring, event IT monitoring, and process monitoring."
"It allows our operations team to have one single application to reference when investigating issues in our environment."
"It has provided us with a single location to host all events to be viewed/monitored by our NOC, which has greatly helped them to streamline their processes."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It's very easy to manage and monitor it."
"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."
 

Cons

"In our company, we faced some issues with the solution’s application endpoint, IP, and the physical location of the transactions."
"BMC TrueSight Operations Management could use some enhancements in the application visibility tools."
"Reporting would be an area for improvement in TrueSight... We have almost 800 customers today on TrueSight and just under 10,000 assets. We need to be able to give a customer some information. If the customer's product fails, they'll ask us, "Did it have a problem beforehand?" We have all those events and we know all the problems it had beforehand. We have to be able to give them access to that kind of reporting. That's an enhancement that we need."
"In a large company of our size, we need multiple people in our company trained. So, I have to take the training classes. Then, I have to go and train the rest of my organization. I would prefer to say to the other people on my team, "Go to this link and..." Or, "Here's a list of training sessions that you can go to which are online and that are free." I think it would help the adoption of their product in the marketplace, personally."
"BMC's solutions for cloud monitoring (monitoring of AWS and Azure resources) are very poor in stability and customization."
"The dashboards could be better. The graphs are extremely limited."
"The solution is overly complex."
"The sizing (which is difficult), the maintenance of it and the upgrade paths. This is a difficult area which is not easy to cover, as every client has a different approach of implementing the product."
"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."
"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."
 

Pricing and Cost Advice

"The tool is moderately expensive."
"The only possible additional cost that I can mention, that you might not be aware of, is that it uses Oracle partitioning, if you use Oracle. There are Oracle partitioning fees that go with that."
"Pricing is very high."
"BMC TrueSight Operations Management is not on the cheaper side, but its pricing is on a case by case basis. Its licensing model is simple and based on the number of devices."
"The cost depends on the usage."
"We're end-of-lifeing it now. Overall, the licensing costs of BMC are a challenge for us in that they're hard costs, whereas open-source monitoring has soft costs, where it's harder to line-item."
"They have changed the licensing fees."
"Pricing is all volume-driven. I think we were paying between $80 and $85 per license. That's per unit, for a perpetual license. You pay it one time and then, every year, you pay 20 percent of that for annual maintenance and support. But now that we've grown, we've purchased tens of thousands of licenses and the cost per license has gone down to something like less than $30..."
"The pricing is quite reasonable, especially when compared to the broader market."
