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

"It is not that expensive of a solution and produces tremendous value."
"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."
"I like this product because it is easy to use and it allows us to have a realistic vision of what is going on at the heart of our network."
"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."
"Thanks to Skylight we have a tool for this kind of investigation and it has reduced our mean time to respond by at least 50 percent."
"The performance of Accedian Skylight is better than other vendors."
"APM analysis is much faster than traditional root cause analysis of application problems."
"Performance Vision saves time diagnosing performance problems and anticipates where investment is needed by pointing to the infrastructure limitations."
"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."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"Nagios is able to minimize server downtime and this in turn helps to generate more revenue."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"The application performance monitoring feature is valuable."
"Inspite of this limitation it is a fantastic product to use at zero cost"
"The most valuable feature is the performance parameters of the system."
 

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."
"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."
"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."
"Human resource costs can be high when dealing with connection issues."
"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."
"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."
"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."
"t was a little hard to get our setup represented in the configuration."
"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."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"I would like to see a sensor that shows the traffic of a user and what they're doing on the network."
"The core version is no match for the XI version."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"Generally, it does what I need it to do, but better error reporting would be great."
 

Pricing and Cost Advice

"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."
"Pricing is a little bit expensive."
"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."
"The pricing is cheaper than other competing products, which is better for our budgets."
"It provides value and the cost is not huge."
"The price is competitive overall, depending on the type of customer."
"It's free."
"Most the plugin features are free."
"Lessening the price point would be an improvement."
"The solution is expensive."
"We are using the open-source, unpaid version."
"Nagios Core is free to use."
"We are using the free version of Nagios Core."
"I would rate the solution's pricing an eight out of ten."
