Senior System Administrator at Interactive Group
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 most valuable feature is the performance parameters of the system."
"The solution's most valuable feature is that it offers proper alerting capabilities."
"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."
"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 features are the reports and the way it generates the report in a graphical manner."
"The solution is very complete and mostly easy to manage."
"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."
"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."
"nGenius provides us with increased visibility during IT deployments."
"NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"The solution's technical support team consists of good engineers and technicians."
"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."
 

Cons

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."
"Generally, it does what I need it to do, but better error reporting would be great."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"Default interface is clunky and slow."
"The UI is a little outdated and graphics could be displayed in a better way."
"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."
"The NetEase reporting structure needs improvement, especially the availability report, which is weak."
"The tool needs to improve the integrations."
"NETSCOUT nGeniusPULSE is not integrated with SolarWinds. They work in different ways."
"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."
"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."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"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."

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