Featured Reviews

Ayobanji Iluyomade - PeerSpot reviewer
The solution is stable and can be used for monitoring and managing events, but it does not provide application or service monitoring features
We are moving from basic monitoring to AIOps, where we can do things like self-healing. We also want to create dashboards for IT and business users to show the status of their services. We have done a couple of demos. I recommend the solution to others. Overall, I rate the product a seven out of ten.
SI
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

"It is breadth. It covers so many different technologies which can roll up into a single console."
"The most valuable features are the rich reports, high performance, and the look and feel of the WebEx webpage are very good."
"What I like best about BMC TrueSight Operations Management is that it allows you to do granular monitoring and improves VM load."
"It works irrespective of the operating system we’re running."
"TSOM's ability to consolidate alerts into a single location and provide filtering of alerts is great."
"I like the event management part."
"The most beneficial part of the product in terms of IT monitoring revolves around the areas involving automation, and it also serves as an end-to-end event management and incident management tool."
"Signature baselines, which have allowed us to fine tune many of our events and significantly reduce the number of events generated."
"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."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
 

Cons

"The solution is overly complex."
"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 our company, we faced some issues with the solution’s application endpoint, IP, and the physical location of the transactions."
"This solution is lacking in application monitoring features. Technical support for this solution also needs improvement, particularly in product knowledge and response time."
"It would be better if the initial setup and deployment were more straightforward."
"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."
"The one piece that I would love to see is a general-purpose, configurable agent which would be a framework that you can deploy on anything, whether it be Java or anything else. It would allow you to easily deploy it on a platform that they support."
"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."
"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."
"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."
 

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."
"It is a relatively inexpensive solution."
"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."
"It is a large, complex product. So, there is a commitment of manpower to deploy it, as it is not a cheap product."
"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."
"The pricing is quite reasonable, especially when compared to the broader market."
