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…

Valuable reporting and alert system with room for PDF export improvements
The NetEase reporting structure needs improvement, especially the availability report, which is weak. It should be generated automatically with minimal human intervention and should be exportable as a PDF. Besides that, an integrated PDF export feature for reports is necessary. Also, the alert mechanism and graphing mechanism need to be integrated properly into Nagios Core. Currently, integrating these requires advanced Linux knowledge. Integration of more visualization tools like Grafana and Prometheus for better graphing and visualization is also recommended.

Quotes from Members

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

Pros

"The response times, with the performance, are really interesting too, where you can see the packet loss."
"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."
"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."
"The feature I used to like the most was its ability to decode layer seven protocols, although this is becoming less useful now that encryption is so widespread."
"I think the analytics features are okay. My customer also likes the interface, the GUI, because it's easy to operate."
"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."
"The performance of Accedian Skylight is better than other vendors."
"I would rate the overall solution ten points out of ten."
"The solution is quite efficient."
"I like that it's very simple to install, easy to manage and deploy, and easy to use for monitoring."
"Provides timely notifications."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"I like the way the solution sends alerts and how it keeps on escalating them."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
 

Cons

"This solution is expensive compared to some others."
"The UI interface of Accedian Skylight could improve."
"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."
"Human resource costs can be high when dealing with connection issues."
"Human resource costs can be high when dealing with connection issues."
"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."
"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."
"The Accedian Skylight user interface still has room for improvement."
"The UI is a little outdated and graphics could be displayed in a better way."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"It is a bit slow due to latency."
"The tool needs to improve the integrations."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"The interface could be improved."
"Nagios Core does not have a graphic display."
"The mapping is a little hard."
 

Pricing and Cost Advice

"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."
"It's not for free, clearly. But on the other hand, it offers very interesting functionality. We pay around €100,000."
"It provides value and the cost is not huge."
"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."
"We understand there's a significant cost difference, but have yet to investigate fully."
"It's free."
"The product is cheaply priced."
"Nagios Core is a cheap solution."
"The solution is expensive."
"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."
"Nagios Core is free to use."
"Most the plugin features are free."
