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…

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Quotes from Members

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

Pros

"The ability to measure performance end-to-end across the cloud data center allows us to take corrective action to keep our channels online."
"APM analysis is much faster than traditional root cause analysis of application problems."
"Skylight is not used on a daily basis, but when it's used it usually helps to fix a problem pretty fast."
"The pricing of Accedian Skylight is really good; the sensors are low cost, their licensing model lets clients start small and grow as they need without being forced into expensive appliances or subscription models, and that is one of the things that we really like about offering it to our clients because they are not left out getting the right sort of information straightaway."
"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."
"The performance of Accedian Skylight is better than other vendors."
"What I like most about Accedian Skylight is that it's a UI application, so using it is easy. I also like that the support for Accedian Skylight is helpful."
"My customer also likes the interface, the GUI, because it's easy to operate."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"They have very accurate and fast support."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"An excellent solution that is easy and intuitive to implement."
"This is a very good solution and it is simple to use, for any company."
"The dashboard allows you to see what's going on in the overall system."
 

Cons

"It needs the possibility to export data because it is not easy to see larger data sets, e.g., for one month."
"Some of the Skylight applications are a little newer, and they're still moving through initial revs."
"I would like to see some improvements in parts of their synthetic transactions, which includes all the latency, jitter, and throughput. I would like to see some Layer 7 analytics in there. I want to be able to do a DNS request, HTTP GET request, or even SIP call point-to-point or via registration."
"This solution is expensive compared to some others."
"Combination with Avaya switches pose some problems."
"The UI interface of Accedian Skylight could improve."
"Support for more VoIP systems, Avaya, etc."
"Human resource costs can be high when dealing with connection issues."
"Nagios XI isn't really good for scaling, in my experience."
"It's in need of more standard plug-ins."
"There are stability issues if you have a large number of hosts and services."
"Nagios XI can improve its GUI for users with a new look."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"The GUI could be improved."
"They need to develop a better integration with a common ticketing system will be great."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
 

Pricing and Cost Advice

"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 solution was previously well-regarded, but after being acquired by Accedian, the prices have significantly increased. This has made it challenging to sell the product due to its high cost. It is an expensive solution."
"Pricing is a little bit expensive."
"We understand there's a significant cost difference, but have yet to investigate fully."
"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."
"It provides value and the cost is not huge."
"The price is competitive overall, depending on the type of customer."
"The pricing is cheaper than other competing products, which is better for our budgets."
"As it is not an agentless tool, I think it is expensive."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"We are using the free version of this solution."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"Nagios XI is open source."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
