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

"The alerting system is very effective."
"Nagios XI is stable."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"An excellent solution that is easy and intuitive to implement."
"The most valuable feature is the monitoring of processes."
"We love Nagios XI due to the fact that JPS Web is very useful."
"I can monitor a phone on a desk to very big servers of any company."
"Nagios XI helped me to draw the network and check for system failures."
"It has a very strong artificial intelligence engine."
"NetMon's best feature is traffic analysis."
"The most valuable feature is the log, which can be analyzed by our SIEM solution."
"It is a stable solution...It is a scalable solution."
"The analytics feature is the most valuable feature."
"LogRhythm NetMon's most impressive feature is that it's a bundled package, so you're not just relying on monthly data; you get a six-month view for more comprehensive indicators of compromise. This dual approach is precious. We implement LogRhythm NetMon in our cybersecurity strategy mainly for compliance and correlation of network, user, and decision activities, particularly for network firewalls and access control."
"The initial setup is straightforward because we can deploy an open server."
"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."
 

Cons

"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"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."
"Technical support is an area that needs improvement. It is not available 24/7."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"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."
"I would like to see better integration with multiple products. Integration is not something that is readily available for most of the products."
"The main concern is that LogRhythm has not improved NetMon but instead introduced a separate product, which many customers, including us, would prefer to be integrated into a single platform for easier management."
"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."
"Sometimes it may be difficult to incorporate new additional databases in NetMon, and we faced some challenges at that time."
"The training for this product is not very good and needs to be improved."
"Could use a topology diagram which would help get an exact visual."
"Sometimes it's hard to find the network devices' self-audit logs."
