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

"It is very stable, has reduced downtime and migration time, and with Skylight we never forget anything."
"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..."
"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."
"APM analysis is much faster than traditional root cause analysis of application problems."
"Network control when experiencing problems indicating "the network is slow"."
"Ease of use; can literally diagnose an issue in about four clicks."
"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 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."
"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."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"We have used this product now for quite some time and we are happy with it."
"The good thing about Nagios Core is it covers everything."
"I would rate the overall solution ten points out of ten."
"The most valuable features are the reports and the way it generates the report in a graphical manner."
"Nagios Core is very configurable. Whatever you want, you can do it."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
 

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."
"Some of the Skylight applications are a little newer, and they're still moving through initial revs. There are certain bugs, but nothing is insurmountable... It will just take a little bit of time for their user interface to get a little bit better."
"Support for more VoIP systems, Avaya, etc."
"Human resource costs can be high when dealing with connection issues."
"The Accedian Skylight user interface still has room for improvement."
"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."
"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."
"I would like to see some improvements in parts of their synthetic transactions, which includes all the latency, jitter, and throughput."
"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."
"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"I would like to see more training videos."
"The UI is a little outdated and graphics could be displayed in a better way."
"There is room for improvement in the graphics."
"I believe Nagios Core will need to provide an option for big data platforms in the future."
"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."
 

Pricing and Cost Advice

"We understand there's a significant cost difference, but have yet to investigate fully."
"It provides value and the cost is not huge."
"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 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 price is competitive overall, depending on the type of customer."
"Pricing is a little bit expensive."
"Nagios Core is a cheap solution."
"The product is cheaply priced."
"Nagios Core is an open source solution, and there are no licensing fees."
"We are using the open-source, unpaid version."
"The solution is expensive."
"It's free."
"I would rate the solution's pricing an eight out of ten."
"The enterprise version has technical support. The version we are using is free."
