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

"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."
"We heavily use the "network analysis" section to dissect and analyze flows."
"The performance of Accedian Skylight is better than other vendors."
"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."
"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..."
"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."
"Customer Service: Very good. Technical Support: Excellent and responsive."
"The ability to measure performance end-to-end across the cloud data center allows us to take corrective action to keep our channels online."
"Dashboard provides monitor of total assets."
"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"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."
"I would rate the overall solution ten points out of ten."
"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."
"The most valuable feature is the performance parameters of the system."
"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."
 

Cons

"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."
"So scalability, at the moment, is pretty bad for us now, because our modus operandi have totally shifted."
"If you want a new version, you go to the website. The hardest part is finding the link, where is that .bin file? Sometimes it's pretty hidden in a document... it's hidden in the release notes or in another file somewhere. And it's usually not on the first page either."
"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."
"This solution is expensive compared to some others."
"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."
"The UI interface of Accedian Skylight could improve."
"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Nagios Core would benefit from aggregations if a particular server goes down."
"Nagios' great customizability is also one of its greatest drawback."
"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."
"We use the free version of Nagios, which needs some administrative skills in order to configure correctly."
"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."
"The UI is a little outdated and graphics could be displayed in a better way."
 

Pricing and Cost Advice

"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."
"It's not for free, clearly. But on the other hand, it offers very interesting functionality. We pay around €100,000."
"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 price is competitive overall, depending on the type of customer."
"Pricing is a little bit expensive."
"It provides value and the cost is not huge."
"We understand there's a significant cost difference, but have yet to investigate fully."
"Nagios Core is free to use."
"We are using the free version of Nagios Core."
"Most the plugin features are free."
"We are using the free version."
"Lessening the price point would be an improvement."
"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."
"It's free."
"Nagios Core is a cheap solution."
