Addresses connectivity issues with real-time monitoring while offering good local support
I had prepared for COC and the client. I work as a vendor for a client using Flow Mount for network performance monitoring. I focus on resolving client-side issues related to Packy Performance and quality use. This involves addressing network device issues, specifically Cisco network devices One…

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

"For us, the most valuable feature is something called TWAMP that allows for real-time traffic in a way that is 10 times lighter than things like SolarWinds. It's in the sub-milliseconds of accuracy, and you can divide tasks so that you can literally see things like the tagging for Quality of Service. That had been incorrect with the carrier, but there was no way on this planet you'd be able to tell a carrier that they're wrong. I have dozens of scenarios where we found "No, that's not right," and got it resolved instantly."
"The solution’s UI and single pane of glass is good. The new dashboard is modern with its new design. The look of it is not pretty, but it is efficient, which is good. It is user-friendly; you can find what you need on the interface quickly."
"Capturing traffic [is very interesting]. Currently, with our configuration, we don't capture the payload of the packets, just the header. But when we want the body, the payload of the packets, we can do a PCAP, and then analyze it within Wireshark."
"This solution has helped to improve the interaction between our network, datacenter, and application teams. I have used other tools, but this tool can pinpoint the root cause of my application or network issue in the majority of the cases. So, it helps different divisions or groups in the IT department to troubleshoot together and get an issue resolved. This tool helps a lot in our day-to-day networking application and IT operations."
"Network control when experiencing problems indicating "the network is slow"."
"It is not that expensive of a solution and produces tremendous value."
"The response times, with the performance, are really interesting too, where you can see the packet loss."
"Skylight is not used on a daily basis, but when it's used it usually helps to fix a problem pretty fast."
"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"
"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."
"Nagios Core is stable."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"Its an awesome product to use."
"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."
"Nagios Core is stable."
"Extensibility is good as this makes it easy to write checks on your own."
 

Cons

"There should be an option to update and upgrade the solution to the new version without having to re-buy it. I have clients switching to other solutions. The old solution is great, but if you change your license to a new one, you have to almost re-buy it completely."
"Some of the Skylight applications are a little newer, and they're still moving through initial revs. There are certain bugs, but nothing is insurmountable... It will just take a little bit of time for their user interface to get a little bit better."
"Because of the policies in Vietnam, we cannot connect the system to the Accedian cloud. It would be good if Accedian could provide a local cloud. In the next release, I would like them to focus on improving and adding more reporting features. This will help the operations teams."
"It needs the possibility to export data because it is not easy to see larger data sets, e.g., for one month. It would be interesting to export data into a PDF or dashboard to keep a history of the situation."
"This solution is expensive compared to some others."
"Support for more VoIP systems, Avaya, etc."
"It needs the possibility to export data because it is not easy to see larger data sets, e.g., for one month."
"The licensing of the virtual pollers is problematic because they are attached to the physical ESX on which they are installed."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"The core version is no match for the XI version."
"It is a bit slow due to latency."
"The tool needs to improve the integrations."
"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
 

Pricing and Cost Advice

"It provides value and the cost is not huge."
"We understand there's a significant cost difference, but have yet to investigate fully."
"Pricing is a little bit expensive."
"It's not for free, clearly. But on the other hand, it offers very interesting functionality. We pay around €100,000."
"The price is competitive overall, depending on the type of customer."
"The pricing of Accedian Skylight is really good. The sensors are low cost. Their model to analytics for sensors is by license, endpoint, or session. With the probes for their analytics, if they get deployed virtually, they are free. The licensing is only based on flows. So, you can effectively deploy probes everywhere in your network. Then, if you want to look at a specific type of traffic, you can enter into it with a very low cost license. You can just use things like spam ports, mirrors, TAPs, and aggregators to optimize what sort of traffic you send to these analysis tools. Then, if you want to start looking at more, you can up your licensed as you go. You are not getting forced into expensive appliances or subscription models."
"The pricing is cheaper than other competing products, which is better for our budgets."
"If you look into Riverbed, it's a licensing nightmare. You need to pay for every type of analysis... If you don't look into licensing, Riverbed and SolarWinds are pretty comparable. But if you look into licensing it would not be smart to go for either of them. On the pure, bare-metal basis, it's the same. But when you get the bare metal and a few basic licenses, then you need all those other licenses just to be sure that there's no issue... One of the great things about Skylight is you have them all, and you actually need them all."
"Nagios Core is free to use."
"The enterprise version has technical support. The version we are using is free."
"Nagios Core is an open source solution, and there are no licensing fees."
"It's 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."
"Lessening the price point would be an improvement."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
