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

"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."
"BMC TrueSight Operations Management can be used to monitor anything on-premises, including the server, applications, log monitoring, event IT monitoring, and process monitoring."
"Automated root cause analysis and predictive capabilities are powerful features that assist in resource utilization and capacity planning."
"The ability to fulfill the role as a manager of managers is fantastic."
"Valuable features include wide support for monitoring, strong event management, service management capability, baselining (analytics) and easy to integrate other tools with it."
"It's a really good tool and most of the issues we've got, they've either fixed or they're fixing to fix."
"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 allows our operations team to have one single application to reference when investigating issues in our environment."
"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."
 

Cons

"We were somewhat limited in TrueSight due to some of the RBAC controls not quite being what we wanted as far as delegating out administrative privileges for implementation. But because we were able to turn requests around pretty well, that burden wasn't too heavy."
"Specifically around application performance monitoring, BMC is definitely not the market leader. The Dynatraces, the New Relics and the like are more of the market leaders in that space. I would like to see them grow that space a little bit more aggressively. It has not really been their bread and butter."
"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."
"I would really like to see out-of-the-box support for monitoring uninterruptible power supplies."
"The solution is a little obsolete."
"The graphs are extremely limited. We don't have a lot of dashboard options. To make reports and dashboards more useful, we usually need to integrate some dashboard solutions."
"The UI for the end users could be improved and more flexible than it is now."
"I would like to see a little more out-of-the-box event correlation and expanded AIOps type capabilities. Where you can train your artificial intelligence operations to be able to memorize an issue once you encounter one scenario, so if you encounter that same problem, you can get to the root cause very quickly."
"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."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"Use conservative figures. In terms of hardware, monitored servers and also effort. The product is not cheap. But as with other products, you get what you pay for."
"Other products are more expensive than BMC TrueSight."
"The cost depends on the usage."
"They have changed the licensing fees."
"The solution is based on endpoints and knowledge models which can be costly."
"It is a large, complex product. So, there is a commitment of manpower to deploy it, as it is not a cheap product."
"Though I have no clue about the tool's actual price, I know that it is astronomical."
"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 pricing is quite reasonable, especially when compared to the broader market."
