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

"I use the solution to monitor servers, databases, Windows, Linux, and web services."
"It is a stable solution."
"I like everything about this tool. I recommend this solution to anyone looking for a standalone solution with high availability meaning that can be used depending on the customers requirements."
"The event management part of TrueSight Operations Management, in my experience, is probably the best in the market."
"The event management part of TrueSight Operations Management, in my experience, is probably the best in the market. You have endless flexibility. You can build your own rules, you have the MRL language, and you can implement any kind of logic on the alerts. It may be correlation, abstraction, or executing something as a result of the alerts. You have almost the whole range of options available for event management using the available customization."
"We utilize BMC TrueSight Operations Management to proactively monitor all of our physical and virtual server environments, and coupled with Entuity for TrueSight Operations Management, we can have a holistic view of our network and server environments health in a single pane of glass."
"The most valuable features of the solution are alert management, alert generation, and event management."
"The BMC TrueSight platform wins probably 80 percent of the time if you look feature by feature."
"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."
"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"It's very easy to manage and monitor it."
"Being open source lets us customize it for our monitoring needs, saving us money."
 

Cons

"One of the things that the TrueSight environment is missing is some of the HA abilities. The data collection server called the ISM doesn't really have the HA functionality or workload balancing. It was missing from the previous product as well. It's missing redundancy."
"The product must provide more AI capabilities."
"This solution is lacking in application monitoring features. Technical support for this solution also needs improvement, particularly in product knowledge and response time."
"Cost is an issue with BMC TrueSight Operations Management."
"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."
"The knowledge modules could be more lightweight in size."
"There are some small limitations with this tool in terms of reporting dashboards that fit all of the requirements of the individual customer."
"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."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"The tool is moderately expensive."
"They have changed the licensing fees."
"Other products are more expensive than BMC TrueSight."
"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..."
"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..."
"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."
"Annual licensing amount depends on the customers requirements. Support is an additional fee and there are options for three and five year support."
"The pricing is quite reasonable, especially when compared to the broader market."
