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

"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."
"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."
"Skylight is not used on a daily basis, but when it's used it usually helps to fix a problem pretty fast."
"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."
"If [the problem] is something related to HTTP or VoIP, then I can have a quick look into the protocols, a process which gives me some good ideas..."
"It is about finding operational problems. When sites go down, we try to determine who is at fault. While there is not much finger-pointing, the solution is just trying to analyse when there is an outage and where do we start looking to fix it. The very nature of why organization chooses to use the solution is to accelerate the meantime to resolution and find where problems lie to get them rectified as quickly as possible."
"It has clearly saved us money."
"Network control when experiencing problems indicating "the network is slow"."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"The solution has a lot of plugins and scripts integrated with it."
"Overall, it's a powerful system."
"For anyone who is interested in using this solution, I would recommend it."
"Nagios is great for verify quality and quantity in a datacenter."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"The solution is pretty stable."
 

Cons

"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."
"We have encountered problems with the license that is connected to the hypervisor on which the virtual appliance is deployed."
"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."
"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."
"It's a bit slow. When I execute a query, something general with a short timeframe that covers one month, for instance, and I do not specify the IP source or IP destination, it can take ages because it has to query the whole database."
"So scalability, at the moment, is pretty bad for us now, because our modus operandi have totally shifted."
"A lower price and more flexible versions will help the product."
"The Accedian Skylight user interface still has room for improvement."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"The GUI could be improved."
"For some, it may be difficult to deploy."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"Implementation on Windows was painful."
"Reporting items needs more improvement and need to be more flexible based on customer needs."
 

Pricing and Cost Advice

"It provides value and the cost is not huge."
"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."
"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."
"We understand there's a significant cost difference, but have yet to investigate fully."
"Pricing is a little bit expensive."
"The price is competitive overall, depending on the type of customer."
"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."
"The pricing is cheaper than other competing products, which is better for our budgets."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"The pricing is high with separate licensing for the product and support."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"Licensing costs are reasonable."

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…
