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

"Network control when experiencing problems indicating "the network is slow"."
"It has clearly saved us money."
"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."
"One valuable feature we have is real-time monitoring for connection issues."
"The response times, with the performance, are really interesting too, where you can see the packet loss."
"I think the analytics features are okay. My customer also likes the interface, the GUI, because it's easy to operate."
"We have found this to be a very valuable toolset, and has paid for itself several times over."
"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."
"The features of Nagios Core that we find most valuable are the plugins we use, we can check the uptime and see how many servers and routers and create groups accordingly."
"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."
"Nagios doesn't get the respect it deserves; most likely due to the fact that it doesn't have a licensing cost."
"The good thing about Nagios Core is it covers everything."
"We can get real time statistics of our servers which improves our monitoring."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
"Nagios Core is stable."
 

Cons

"A lower price and more flexible versions will help the product."
"Combination with Avaya switches pose some problems."
"This solution is expensive compared to some others."
"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."
"The Accedian Skylight user interface still has room for improvement."
"For the PVX, they are in the process of getting the results to export to cloud and SaaS for analytics. They told me that this will happen later this year. Right now, for the most part, I create that data myself."
"The licensing of the virtual pollers is problematic because they are attached to the physical ESX on which they are installed."
"Embed a warning system to a mailbox when it exceeds the threshold for use of bandwidth over a given period of time."
"They should simplify the features so it becomes easier to setup out of the box."
"Nagios Core would benefit from aggregations if a particular server goes down."
"Application level monitoring is limited."
"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."
"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."
"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."
"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."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
 

Pricing and Cost Advice

"Pricing is a little bit expensive."
"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 pricing is cheaper than other competing products, which is better for our budgets."
"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."
"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."
"We understand there's a significant cost difference, but have yet to investigate fully."
"It's free."
"Most the plugin features are free."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"Nagios Core is an open source solution, and there are no licensing fees."
"The enterprise version has technical support. The version we are using is free."
"Nagios Core is free to use."
