Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

Has supported real-time event detection and reporting accuracy while database integration has required extra effort
Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time. However, currently, it is not giving many challenges.It is difficult to integrate NetMon with other databases. We can customize NetMon's monitoring views, but it is done by the team who handles it, as it is outsourced.

Quotes from Members

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

Pros

"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"The alerting system is very effective."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"The dashboard allows you to see what's going on in the overall system."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"Compared to many other products in the market, I think LogRhythm has the highest cost to performance ratio in terms of its value."
"The initial setup is straightforward because we can deploy an open server."
"It has a very strong artificial intelligence engine."
"NetMon's best feature is traffic analysis."
"We are using NetMon's real-time traffic analysis regularly with a team of four members who effectively monitor all alerts and events, which has helped them identify whether there could be a severe incident."
"It is a stable solution...It is a scalable solution."
"The protocols with which you see the traffic for a particular website that a client has in their environment, for example, are valuable. We can monitor whether the traffic is up to the mark or whether they need to add more bandwidth. Also, we can see if we're able to get real-time environment data as well. The customization dashboard is really good. LogRhythm NetMon has its own in-built dashboards which are helpful in guiding customization."
"Visibility is a valuable feature, the ability to see even if the traffic is not going into the firewall"
 

Cons

"The product does not have SAP monitoring."
"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"Its simple deployment but complexity comes once you have to import more plugins."
"The user interface needs improvement."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"The platform's integration features often need to be improved."
"The training for this product is not very good and needs to be improved."
"Some of the automated tasks we can perform on QRadar cannot be performed on LogRhythm because the solution has limitations."
"There is an issue with tunneling in relation to how the connectivity is established between the end devices and where NetMon is installed. On the console, I often observe that there's a difference of a few seconds or maybe a minute, and this lag time should not be there."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"One thing that surprised me was the current version of LogRhythm does not natively support Windows 2016."
"LogRhythm NetMon's pricing model is an area of concern that should be made a little bit cheaper in comparison to the other players in the market currently."
"Their technical support isn't so great."
