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

"Ease of use; can literally diagnose an issue in about four clicks."
"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."
"Performance Vision saves time diagnosing performance problems and anticipates where investment is needed by pointing to the infrastructure limitations."
"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."
"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 performance of Accedian Skylight is better than other vendors."
"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."
"Network control when experiencing problems indicating "the network is slow"."
"Provides timely notifications."
"We have used this product now for quite some time and we are happy with it."
"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."
"This product covers all of our infrastructure health checks, and has triggers for us to alert us to any unusual behaviour of the monitored systems."
"The good thing about Nagios Core is it covers everything."
"I would rate the overall solution ten points out of ten."
"Nagios Core is a great solution for monitoring pretty much any size of deployment but you do need to know your way around a Linux system to set it up and run it."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
 

Cons

"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."
"Increase the drive’s capacity to store more data, and maybe switch to a database system similar to 3Big-Data."
"A lower price and more flexible versions will help the product."
"Embed a warning system to a mailbox when it exceeds the threshold for use of bandwidth over a given period of time."
"Support for more VoIP systems, Avaya, etc."
"Combination with Avaya switches pose some problems."
"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."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"This is the open source product, so it's a toolkit rather than a complete solution."
"The tool needs to improve the integrations."
"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."
"The scalability needs improvement, it's not scalable at this time."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"Default interface is clunky and slow."
 

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."
"Pricing is a little bit expensive."
"We understand there's a significant cost difference, but have yet to investigate fully."
"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."
"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 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 provides value and the cost is not huge."
"The product is cheaply priced."
"Nagios Core is an open source solution, and there are no licensing fees."
"Most the plugin features are free."
"It's free."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"Lessening the price point would be an improvement."
"Nagios Core is a cheap solution."
