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

"The response times, with the performance, are really interesting too, where you can see the packet loss."
"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."
"It is very stable, has reduced downtime and migration time, and with Skylight we never forget anything."
"Network control when experiencing problems indicating "the network is slow"."
"It has clearly saved us money."
"I always have the Skylight dashboard on one of my screens... Now you can create your own dashboard, specific to an application, specific to a server, or to something else."
"Performance Vision saves time diagnosing performance problems and anticipates where investment is needed by pointing to the infrastructure limitations."
"We heavily use the "network analysis" section to dissect and analyze flows."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"The most valuable feature depends on the project. It's great if you need to check to ensure a service is running 24/7. I can use the full solution for free, and it's flexible. If I need to add a dashboard, I can integrate it with Nagios. Cloud synchronization is wonderful."
"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 of Nagios Core is it allows us to develop and add as many plugins as we want."
"The good thing about Nagios Core is it covers everything."
"The solution is quite efficient."
"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."
"Extensibility is good as this makes it easy to write checks on your own."
 

Cons

"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."
"The UI interface of Accedian Skylight could improve."
"So scalability, at the moment, is pretty bad for us now, because our modus operandi have totally shifted."
"Embed a warning system to a mailbox when it exceeds the threshold for use of bandwidth over a given period of time."
"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."
"Combination with Avaya switches pose some problems."
"Pricing is a little bit expensive."
"The licensing of the virtual pollers is problematic because they are attached to the physical ESX on which they are installed."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"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 scalability needs improvement, it's not scalable at this time."
"I like to have the option to configure Nagios using the web interface."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"The alerting mechanism in Nagios Core could be improved."
"Nagios Core is not easy to use, so I don't recommend it for everyone."
 

Pricing and Cost Advice

"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."
"Pricing is a little bit expensive."
"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 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."
"It provides value and the cost is not huge."
"The price is competitive overall, depending on the type of customer."
"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."
"Nagios Core is an open source solution, and there are no licensing fees."
"It's free."
"It's free."
"Most the plugin features are free."
"Lessening the price point would be an improvement."
"I would rate the solution's pricing an eight out of ten."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
