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 tailoring of the knowledge modules has been particularly useful as I can streamline the agents to only report on critical events."
"It is a stable solution."
"The Event Management is outstanding; still is the most interesting part of the product."
"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."
"The solution has a very good business event manager tool."
"The most valuable features are the rich reports, high performance, and the look and feel of the WebEx webpage are very good."
"It's a really good tool and most of the issues we've got, they've either fixed or they're fixing to fix."
"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]."
"It's very easy to manage and monitor it."
"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

"It would be better if the initial setup and deployment were more straightforward."
"On Windows we went to application HA and, quite honestly, it was terrible."
"One of the things that the TrueSight environment is missing is some of the HA abilities."
"The L1 and L2 support team need improvement in terms of product knowledge, but most of the time, they're always available and always trying to help us out."
"Deployment requires lots of resources (servers). It has too many consoles."
"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."
"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."
"Specifically around application performance monitoring, BMC is definitely not the market leader. The Dynatraces, the New Relics and the like are more of the market leaders in that space. I would like to see them grow that space a little bit more aggressively. It has not really been their bread and butter."
"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."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"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."
 

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..."
"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."
"The solutions are not the cheapest but are robust and stable. License model is rather complex and BMC do often change the model."
"They have changed the licensing fees."
"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..."
"We did a five-year, multimillion dollar deal."
"The pricing is quite reasonable, especially when compared to the broader market."
