Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."

"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."

"Extensibility is good as this makes it easy to write checks on your own."

"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."

"Provides timely notifications."

"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."

"We have used this product now for quite some time and we are happy with it."

"Its an awesome product to use."

More Nagios Core pros

"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."

"We have seen a measurable decrease in mean time to know and mean time to repair, and because the tool allows us to get to things a lot quicker and see things a lot quicker, we have actually reduced those times and it has definitely helped with our network uptime, with an improvement in uptime of at least 50 percent."

"I like the single pane of glass view. I like being able to go to one place instead of having to hunt around for everything."

"I like the single pane of glass view because it presents everything in one window, obviously. You can see it all. With a quick glance, you get a pretty good snapshot of what's going on in a particular situation."

"The solution's technical support team consists of good engineers and technicians."

"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."

"NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds."

Cons

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"Application level monitoring is limited."

"The core version is no match for the XI version."

"It is a bit slow due to latency."

"This solution is not scalable at all. If you want to add an AI, or if you wanted to monitor different types of metrics, you won't get the most out of it."

"The initial setup process could be easier."

More Nagios Core cons

"They require a lot of manual effort as traffic flows, networks, and formal times change."

"NETSCOUT nGeniusPULSE is not integrated with SolarWinds. They work in different ways."

"Usability is the area with the biggest room for improvement. We've found that with NETSCOUT, while it's a fantastic product, the usability is a major factor because there are just way too many clicks. It's obvious, from our experience, that the people who are developing the product aren't using it."

"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out. We need something a little more granular."

"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out."

"Before an attack starts, seeing the traffic behavior and activities would be great. The tool should also share alerts since it is an area where the product has certain shortcomings."

"They require a lot of manual effort as traffic flows, networks, and formal times change."

Pricing and Cost Advice

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"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."
