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 performance of Accedian Skylight is better than other vendors."
"We heavily use the "network analysis" section to dissect and analyze flows."
"Performance Vision saves time diagnosing performance problems and anticipates where investment is needed by pointing to the infrastructure limitations."
"It is very stable, has reduced downtime and migration time, and with Skylight we never forget anything."
"Skylight is not used on a daily basis, but when it's used it usually helps to fix a problem pretty fast."
"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."
"I think the analytics features are okay. My customer also likes the interface, the GUI, because it's easy to operate."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"I would rate the overall solution ten points out of ten."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"The reporting structure and the feature set are valuable to me."
"Using Nagios, I'm managing more than 1000 services, which involves the following operating nodes: IBM AIX, Red Hat Enterprise Linux, HP-Unix, Windows enterprise-grade OS, Cisco router/switches, FortiGate and WatchGuard firewalls, APC UPS systems, and many more."
"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."
"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."
 

Cons

"Pricing is a little bit expensive."
"A lower price and more flexible versions will help the product."
"The Accedian Skylight user interface still has room for improvement."
"The UI interface of Accedian Skylight could improve."
"Increase the drive’s capacity to store more data, and maybe switch to a database system similar to 3Big-Data."
"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."
"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."
"Default interface is clunky and slow."
"The core version is no match for the XI version."
"t was a little hard to get our setup represented in the configuration."
"Don't use it. If you're starting from scratch, there are products that scale better and perform better, and they use the same plugin syntax as they were initially Nagios forks."
"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."
"The mapping is a little hard."
"Nagios Core would benefit from aggregations if a particular server goes down."
"The dashboard should be improved."
 

Pricing and Cost Advice

"It provides value and the cost is not huge."
"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."
"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."
"We understand there's a significant cost difference, but have yet to investigate fully."
"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 pricing is cheaper than other competing products, which is better for our budgets."
"Pricing is a little bit expensive."
"The solution is expensive."
"We are using the free version."
"We are using the open-source, unpaid version."
"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."
"It's free."
"The enterprise version has technical support. The version we are using is free."
"The product is cheaply priced."
"Most the plugin features are free."
