I work with BMC TrueSight and have been using it for eight-plus years BMC TrueSight brought a positive impact and benefits to our organization. The customization part is one of the advantages of the product, along with the monitoring capabilities. Automated root cause analysis and predictive…

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

"The Event Management is outstanding; still is the most interesting part of the product."
"Having a good monitoring implementation has made a world of difference to our operations teams."
"It is a scalable solution."
"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."
"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."
"Intelligent solution with a proactive monitoring feature and consolidated dashboard that's stable and easy to scale."
"The ability of this platform to monitor the very diverse assets that we maintain around the world is its most valuable feature... We support a vast array of manufacturers' equipment, like HP, IBM, Cisco, Dell, EMC, Hitachi... We can do it all with [this] one [solution]."
"I like the deep-dive detail and end-user metrics data."
"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

"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."
"The dashboards are not good. We have a limited dashboard, and if we want better dashboards, we need to use other solutions like Grafana because the TrueSight dashboards are not good."
"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."
"I would really like to see out-of-the-box support for monitoring uninterruptible power supplies."
"I would like to see a little more out-of-the-box event correlation and expanded AIOps type capabilities. Where you can train your artificial intelligence operations to be able to memorize an issue once you encounter one scenario, so if you encounter that same problem, you can get to the root cause very quickly."
"Specifically around application performance monitoring, BMC is definitely not the market leader."
"In a large company of our size, we need multiple people in our company trained. So, I have to take the training classes. Then, I have to go and train the rest of my organization. I would prefer to say to the other people on my team, "Go to this link and..." Or, "Here's a list of training sessions that you can go to which are online and that are free." I think it would help the adoption of their product in the marketplace, personally."
"I think the solution is overly complex and requires a lot of resources."
"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."
"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
 

Pricing and Cost Advice

"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."
"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."
"It is a large, complex product. So, there is a commitment of manpower to deploy it, as it is not a cheap product."
"Other products are more expensive than BMC TrueSight."
"The solutions are not the cheapest but are robust and stable. License model is rather complex and BMC do often change the model."
"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..."
"It is a relatively inexpensive solution."
"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 pricing is quite reasonable, especially when compared to the broader market."
