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

"One valuable feature we have is real-time monitoring for connection issues."
"When a remote contact complains about a slow application, we can immediately pinpoint the cause of concern."
"It is very stable, has reduced downtime and migration time, and with Skylight we never forget anything."
"We have found this to be a very valuable toolset, and has paid for itself several times over."
"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 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."
"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."
"We heavily use the "network analysis" section to dissect and analyze flows."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The ROI is very good."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"It has a lot of flexibility for customization and a wide range of metrics."
"I really found Nagios a perfect fit for us and a good product to work with."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"I can monitor a phone on a desk to very big servers of any company."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
 

Cons

"Support for more VoIP systems, Avaya, etc."
"Combination with Avaya switches pose some problems."
"A lower price and more flexible versions will help the product."
"Pricing is a little bit expensive."
"Increase the drive’s capacity to store more data, and maybe switch to a database system similar to 3Big-Data."
"This solution is expensive compared to some others."
"Human resource costs can be high when dealing with connection issues."
"The licensing of the virtual pollers is problematic because they are attached to the physical ESX on which they are installed."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
"It can be quite difficult to know which drivers and agents to use when setting up."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
 

Pricing and Cost Advice

"We understand there's a significant cost difference, but have yet to investigate fully."
"It provides value and the cost is not huge."
"Pricing is a little bit expensive."
"The pricing is cheaper than other competing products, which is better for our budgets."
"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."
"It's not for free, clearly. But on the other hand, it offers very interesting functionality. We pay around €100,000."
"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."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"As it is not an agentless tool, I think it is expensive."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is an expensive solution."

I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
