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

"It is easy to use, and the performance metrics are helping us to know our network better."
"The biggest selling point is putting the power of creating dashboards and reports into end users' hands."
"It's a solution which is highly recommended."
"The integration to the other products that we use: NFA, we use ADA, we use Spectrum; and CAPM integrates all those into a single pane of glass, for performance."
"In the last three years, it has had a great improvement in its stability; it is great that it works and we have had no outages in this time."
"Spectrum is very good at monitoring all network faults and configurations."
"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."
"I think the product has matured a lot, and I’m impressed with CA when I hear about new features."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."
"We use the product to monitor server applications."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"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."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
 

Cons

"The dashboard features are very function rich, but the reporting feature is probably not as rich as we'd like it to be."
"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. ​"
"The certificates are not complete. CA needs to provide more support for the product through certificates."
"One of the greatest challenges we have encountered are the polling cycles."
"For CA PM, there should be a way of easily migrating the reports coming from eHealth going to CA Performance Center, since CA PC is replacing eHealth."
"The database should have higher availability in case of an incident."
"I would like to have more tasks, graphs, and possibilities for linking to the graphs and reports added to the solution."
"Install is done as root, which is a security no-no, and the database IO requirements were not stated correctly, which lead to a year of instability."
"The UI is a little outdated and graphics could be displayed in a better way."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"We're using the free version, which limits us in terms of the things that we can do."
"The alerting mechanism in Nagios Core could be improved."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"Nagios Core would benefit from aggregations if a particular server goes down."
"I would like to see more training videos."
"Lessening the price point would be an improvement."
 

Pricing and Cost Advice

"They should provide more scalable licensing for the product."
"The tool's pricing is based on the number of network devices."
"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."
"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."
"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."
"The enterprise version has technical support. The version we are using is free."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"Nagios Core is a cheap solution."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is an open source solution, and there are no licensing fees."
"We are using the free version."
"The product is cheaply priced."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
