The solution is stable and can be used for monitoring and managing events, but it does not provide application or service monitoring features
We are moving from basic monitoring to AIOps, where we can do things like self-healing. We also want to create dashboards for IT and business users to show the status of their services. We have done a couple of demos. I recommend the solution to others. Overall, I rate the product a seven out of ten.
Nishith-Vyas - PeerSpot reviewer
Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"The most valuable features of BMC TrueSight Operations Management are the blackouts and event management."
"It works irrespective of the operating system we’re running."
"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 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 major advantage of the product is estate management."
"It allows our operations team to have one single application to reference when investigating issues in our environment."
"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."
"The most valuable features of the solution are alert management, alert generation, and event management."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"Provides timely notifications."
"Nagios Core is stable."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
 

Cons

"Application performance management (APM) is an area with certain shortcomings in the solution that needs improvement. I"
"In our company, we faced some issues with the solution’s application endpoint, IP, and the physical location of the transactions."
"The solution could improve its price."
"The solution is a little obsolete."
"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."
"BMC TrueSight Operations Management could use some enhancements in the application visibility tools."
"The pricing could be better."
"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 dashboard should be improved."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"t was a little hard to get our setup represented in the configuration."
"There is room for improvement in the graphics."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The interface could be improved."
 

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 very high."
"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..."
"Though I have no clue about the tool's actual price, I know that it is astronomical."
"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."
"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..."
"Other products are more expensive than BMC TrueSight."
"The cost depends on the usage."
"It's free."
"We are using the open-source, unpaid version."
"We are using the free version."
"Most the plugin features are free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"It's free."
