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

"Helix Innovation Studio is a very good feature. It allows us to develop our own enterprise applications and make them available for the customers."
"The initial setup of BMC TrueSight Operations Management was easy."
"The major advantage of the product is estate management."
"The BMC TrueSight platform wins probably 80 percent of the time if you look feature by feature."
"We can verify uptimes as another source of keeping devices in compliance."
"We have one application, which is fairly large. In the past, we had Level 1 and 2 NOC support teams who were responsible for watching dashboards. When they saw an issue in the application, they would call Level 2 or 3 support and escalate the call, if necessary. 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. We no longer have people watching the dashboard. We have events which are processed automatically through the system and get to the right people. We had six people in L1s, and now have one. So, we reduced five out of six headcount, which is pretty significant."
"It allows our operations team to have one single application to reference when investigating issues in our environment."
"I like the deep-dive detail and end-user metrics data."
"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."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
 

Cons

"The solution's support service could be better."
"It's too complex, too many servers are required, there are too many different components in the solution, and a lot of agents are required."
"Deployment requires lots of resources (servers). It has too many consoles."
"This solution is lacking in application monitoring features. Technical support for this solution also needs improvement, particularly in product knowledge and response time."
"The dashboards could be better. The graphs are extremely limited."
"Pricing is very high."
"The knowledge modules could be more lightweight in size. At present, the installation packages can be quite large."
"Multi-tenancy and the scalability have been challenges along the way, as we've grown."
"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

"The price of BMC TrueSight Operations Management is very high. If there was more flexibility with the sizing of the licensing it would be helpful, especially during the pandemic. We have wanted to expend but the licensing cost is too high."
"Pricing is very high."
"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."
"The tool is moderately expensive."
"Consider scalability very carefully: how much you want to monitor and what components are very important. Then, depending on these two things, filter out unwanted metrics or attributes. If you do a good job at filtering the data, then your licensing costs will be manageable."
"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."
"Other products are more expensive than BMC TrueSight."
"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."
