Flexibility and detailed performance stats enable effective network monitoring
Spectrum is very good at monitoring all network faults and configurations. It enables me to take action based on network issues. The Performance Management provides detailed network performance stats, including CPU, memory, and interface bandwidth. Additionally, Spectrum is flexible and allows me to organize and treat devices uniquely without impacting other devices.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.

Quotes from Members

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

Pros

"The feature that is inherent to its core, of being able to graphically represent a trend and status, is nice."
"It gave us one location, one place to do all of group administration, and to build dashboards, and device administration, inventory counts... it really reduced our overall administrative overhead."
"The licensing is very straightforward; it doesn't matter how many devices you have and would like to monitor, it's very straightforward."
"There is another component of the tool called Network Flow Analysis. It gives us the ability to troubleshoot issues which do not appear right away."
"​When devices are having performance issues, it proactively build dashboards which allow us to go and do health checks, and resolve problems before they become an issue.​"
"When we deployed it, right out of the box we were able to stand up Performance Management within two weeks, in our production environment, with full discovery and relevant information, actual information, that we could use in our command center, our 24/7 operations center."
"Downloads and records are the most valuable features."
"Technical support is very responsive and knowledgeable."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"We have used this product now for quite some time and we are happy with it."
"The application performance monitoring feature is valuable, and we primarily use it for user experience monitoring and determining which layer the problem happened to resolve it."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"We can get real time statistics of our servers which improves our monitoring."
 

Cons

"It seems like we escalate more than I would like to. If anything, they should look at how the tier support goes in place."
"When it goes through discovery, or whatever it is doing in the back-end that slows it down, sometimes we get some failures with it. ​"
"CA PM Business Hours Filtering: I understand that all monitoring systems have defects. The Business Hours Filtering does not always function properly. Sometimes, when applying business hours to CA PM reports that are 30 or more days in duration, the report generation times out and does not display results. We have other CA PM reports that, when we apply Business Hours Filtering, the report results displayed are the same as without the filter. We are not sure if this is a defect in CA PM or if it is a result of our complex configuration (folder structure) and application of business hours."
"Today, tenants are bound to a data collector which requires a lot of networking and resources to configure."
"Spectrum's topology view sometimes does not rebuild automatically when a device is shut down and reconnected. It requires manual discovery and rebuilding of the topology, which I hope can be improved."
"It would be helpful if CA provided online training for its customers."
"I have mixed feeling about the scalability. I feel like there are things which are being put into UIM right now that are not being included in Performance Center that we need to see in Performance Center. We are kind of being driven to buy UIM, and I can't justify it.​"
"DX Performance Management should increase high availability. If one of my two data centers goes offline and the other is operational, I need a seamless transition from the primary to the secondary data center. It's crucial to maintain consistent monitoring of the devices during this transition. Therefore, I require continuous, 24/7 monitoring of my system using this tool."
"The initial setup process could be easier."
"The mapping is a little hard."
"Generally, it does what I need it to do, but better error reporting would be great."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
"The user interface could be more interactive because it is pretty basic."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
 

Pricing and Cost Advice

"I like the licensing model because it's device-based."
"Do your homework and know how many devices you will be managing out of the gate. Be sure to project what your growth will be each year."
"The tool's pricing is based on the number of network devices."
"They should provide more scalable licensing for the product."
"We purchase a license to use the solution every three years and we have multiple contracts. They have been increasing the price annually. We have a baseline for three years and then we need to pay the difference from the baseline, and we are in the process of negotiating a new price for all the licenses we need. The price overall is affordable."
"We were looking at other vendors in the marketplace for NetFlow, and CA just beat everybody else in price, cost, and the size to implement. ​"
"Nagios Core is a cheap solution."
"We are using the free version of Nagios Core."
"We are using the free version."
"Nagios Core is an open source solution, and there are no licensing fees."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"Nagios Core is free to use."
"The product is cheaply priced."
"It's free."
