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 has provided us with a single location to host all events to be viewed/monitored by our NOC, which has greatly helped them to streamline their processes."
"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."
"TSOM's ability to consolidate alerts into a single location and provide filtering of alerts is great."
"From the time we get the incident logged to the time we get the customer back up and running, it has improved that by 33 percent or greater."
"It is a stable solution."
"It is breadth. It covers so many different technologies which can roll up into a single console."
"The most valuable features of BMC TrueSight Operations Management are the blackouts and event management."
"Using the TrueSight platform we can monitor server performance and notify the customers using the integrated ticketing for events. We can let them know if there are any issues with a server, or application, or database."
"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."
"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

"The graphs are extremely limited. We don't have a lot of dashboard options. To make reports and dashboards more useful, we usually need to integrate some dashboard solutions."
"Cost is an issue with BMC TrueSight Operations Management."
"I definitely would like to see more improvement in the self-diagnostics. I need to know when anything is not working or collecting, long before our customer finds it."
"I would like them to improve the deep-dive details, tracing, and data agents in this product. We have EUEM, an end-user experience monitoring appliance. This one's quicker than the current one, and reporting side and filtration side are very bad. There are many details we look at and explain what we receive information in the current one, but we cannot have historical data like we do with EUEM. We cannot have a powerful point to look for specific traffic from a specific application and a specific browser. We don't have it in the new one. The current BMC also needs to add the thing that control versions."
"The product must provide application or service monitoring features."
"It's a far more complex technology than I perceived at the beginning to deploy."
"There are some complexities with deployment that could be improved in BMC TrueSight."
"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."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
 

Pricing and Cost Advice

"Though I have no clue about the tool's actual price, I know that it is astronomical."
"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."
"The tool is moderately expensive."
"It is a relatively inexpensive solution."
"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 solution is based on endpoints and knowledge models which can be costly."
"Other products are more expensive than BMC TrueSight."
"Use conservative figures. In terms of hardware, monitored servers and also effort. The product is not cheap. But as with other products, you get what you pay for."
"The pricing is quite reasonable, especially when compared to the broader market."
