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

"The most valuable features of BMC TrueSight Operations Management are the blackouts and event management."
"The solution's event management capabilities are fantastic. We do a best of breed. If, on the network side, they use a different tool, we pull all that data in so that we have a single console. It's kind of like the monitor of monitors. We're able to aggregate all the different types of data sets, whether it's log data, app data, OS data, infrastructure data, or network data. We're able to aggregate all those events and then correlate and be able to say we're having an event."
"I believe that the ease of use and UI is great"
"The fact that they have a very integrated relationship with Sentry Software, the Knowledge Module, is valuable... The richest feature for us is the number of Knowledge Modules that we can load into the product to add breadth of service to the customer. It enables us to move up the operational stack from hardware, to operating system, to application, and to cloud... That enables us to provide one pane of glass over all those layers - hardware, OS, app, and cloud."
"The most valuable features of the solution are alert management, alert generation, and event management."
"It is breadth. It covers so many different technologies which can roll up into a single console."
"It is very helpful to be able to apply rule-based routing to alerts."
"The most valuable feature of BMC TrueSight Operations Management is the dashboard presentation server."
"Being open source lets us customize it for our monitoring needs, saving us money."
"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."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
 

Cons

"BMC TrueSight Operations Management could improve the reporting."
"The product must provide application or service monitoring features."
"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."
"I think the ease of deployment needs to be looked at. It would be great if the deployment was faster and easier."
"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."
"The dashboards are not good. We have a limited dashboard, and if we want better dashboards, we need to use other solutions like Grafana because the TrueSight dashboards are not good."
"There are some complexities with deployment that could be improved in BMC TrueSight."
"We have a unique use case because BMC typically sells this solution into enterprises that are deploying it within their IT, versus to a managed services provider like us where we're supporting thousands of customers. Multi-tenancy and the scalability have been challenges along the way, as we've grown... If anything could have gone better as we were ramping this up and adding a lot of volume to it, I would say it's the scalability. That would be one thing that could be improved."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"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."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
 

Pricing and Cost Advice

"We did a five-year, multimillion dollar deal."
"There is a big upfront cost when you buy the license, then there is annual maintenance. We look at, if I bought a license and paid for maintenance for five years, then average it out, what would be my monthly cost. We have had some of the competing tools come in around four dollars. This is coming in as a premium, which is why I don't have it deployed as I would like it. Therefore, we're in negotiations right now. If I can get it down to the four dollar range, I will triple my deployment in a year and a half."
"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."
"It is a relatively inexpensive solution."
"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."
"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 solution is based on endpoints and knowledge models which can be costly."
"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."
