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."
"It is a very stable product."
"The major advantage of the product is estate management."
"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."
"BMC TrueSight Operations Management is a firefighter that will help you when problems come."
"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 solution has a very good business event manager tool."
"The event management part of TrueSight Operations Management, in my experience, is probably the best in the market."
"It's very easy to manage and monitor it."
"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."
"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

"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."
"I would really like to see out-of-the-box support for monitoring uninterruptible power supplies."
"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."
"More modules for less popular applications and better documentation."
"The solution is based on endpoints and knowledge models which can get costly. Pricing is a little bit high so I rate it a six out of ten."
"There are some small limitations with this tool in terms of reporting dashboards that fit all of the requirements of the individual customer."
"The solution's support service could be better."
"BMC TrueSight Operations Management could use some enhancements in the application visibility tools."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"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."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."

Pricing and Cost Advice

"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..."
"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 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."
"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 pay license fees of between $150 and $200 per asset. There is an enterprise software license fee, and then you pay a percentage for your maintenance, and then Premier Support. For example, if you buy a two-year license for the product, then the maintenance fee is added to that for two years at X percent a year. Then there's a small fee on top of that for Premier Support..."
"Other products are more expensive than BMC TrueSight."
"The cost depends on the usage."
"The tool is moderately expensive."
"The pricing is quite reasonable, especially when compared to the broader market."
