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.

Has improved traffic visibility and simplified dashboard use, but could benefit from better integration with other tools

NETSCOUT nGeniusPULSE works very well in our case. We have not experienced any troubles with traffic analysis SolarWinds has a dashboard that is older and not as user-friendly. NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds. NETSCOUT nGeniusPULSE is not…

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 features are the reports and the way it generates the report in a graphical manner."

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

"We mostly use Nagios Core to integrate with Python and Bash Script."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"The application performance monitoring feature is valuable."

"The solution's most valuable feature is that it offers proper alerting capabilities."

"The solution is very complete and mostly easy to manage."

"Nagios Core is stable."

More Nagios Core pros

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

"nGenius provides us with increased visibility during IT deployments."

"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."

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

"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."

"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."

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

Cons

"The initial setup process could be easier."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"The dashboard should be improved."

"I would like to see more training videos."

"The interface could be improved."

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"It is a bit slow due to latency."

"They should simplify the features so it becomes easier to setup out of the box."

More Nagios Core cons

"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."

"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."

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

"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."

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

Pricing and Cost Advice

"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."

"Nagios Core is free to use."

"It's free."

"Nagios Core is a cheap solution."

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