Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"BMC TrueSight Operations Management is a firefighter that will help you when problems come."
"The event management part of TrueSight Operations Management, in my experience, is probably the best in the market."
"TrueSight Operations Manager is a combination of different components (applications) like Presentation Server, Impact Manager, and AppVisibility Manager and IT's Data Analytics, but it provides a seamless integration and a holistic view with Application and Infrastructure Health views."
"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."
"Automated root cause analysis and predictive capabilities are powerful features that assist in resource utilization and capacity planning."
"The very fact that we've been on it for ten years is a testament, as we continue to make the investment and pay the renewal because the return has been fantastic."
"It provides common administration, and a Single Sign-On Platform with RBAC, which eases the cross launch between multiple tools"
"The solution is stable, we have not needed to speak to the vendor regarding any issues, it has been operating very well."
"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."
"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."
 

Cons

"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."
"I would like to see a little more out-of-the-box event correlation and expanded AIOps type capabilities."
"The pricing could be better."
"BMC TrueSight Operations Management could use some enhancements in the application visibility tools."
"The product must provide application or service monitoring features."
"The dashboard and performance graphs should include a way to automatically schedule and export reports."
"On Windows we went to application HA and, quite honestly, it was terrible."
"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."
"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."
"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

"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."
"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..."
"It is a relatively inexpensive solution."
"Other products are more expensive than BMC TrueSight."
"Though I have no clue about the tool's actual price, I know that it is astronomical."
"The solution is based on endpoints and knowledge models which can be costly."
"The cost depends on the usage."
"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..."
"The pricing is quite reasonable, especially when compared to the broader market."
