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

"You can create intelligent alerts so you have enough time to replace the router or interface before it's full. The same is applicable for CBQoS channels.​"
"One of the most valuable features is the ease of use."
"Considering all these factors, it's really a good and easy product for analyzing your network performance, health status, and the quality of services."
"It makes things faster when we have our network operations center, they can look at their dashboards that we've created for them, and they can see problems immediately."
"The capability where not only the traditional SNMP information is captured but also the netflow data; who is consuming the data on the WAN, and voice-related information, is helpful. The voice quality makes it very easy for first- and second-line operators to see where the issue is, and who is impacted."
"It is easy to use, and the performance metrics are helping us to know our network better."
"Scalability is great."
"The network teams have transitioned to becoming proactive in responding to network performance issues, rather than being just reactive to outages."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"It sends alerts to the right people which ensures there is no delay in the correct person or team looking into issues, and it has helped to reduce downtime in the production environment to almost zero so we now spend less time on network or server administration."
 

Cons

"The solution could improve the database model. It is also not very good because they have a lot of interconnections with other data sources, such as NFA and VNA."
"This solution's implementation process could be quicker. They could also optimize the hardware requirements."
"It could be a little easier to integrate new metrics."
"It would be helpful if CA provided online training for its customers."
"Some of the individual report views, the way some of the columns sort, there's room for improvement in giving us more flexibility in being able to sort reports based, for example, on what columns the metrics fall under."
"The database should have higher availability in case of an incident."
"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."
"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. ​"
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"I would like to see more training videos."
"It is a bit slow due to latency."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"The dashboard should be improved."
"The configuration and reporting modules need to be improved."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
 

Pricing and Cost Advice

"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. ​"
"I like the licensing model because it's device-based."
"It's free."
"Most the plugin features are free."
"The solution is expensive."
"Nagios Core is free to use."
"I would rate the solution's pricing an eight out of ten."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"The enterprise version has technical support. The version we are using is free."
"We are using the free version."
