It tremendously cuts down our troubleshooting timeframe, but needs advanced SLA monitoring and reporting

They can do a better job with SLA reporting. It does some basic reporting, but it really doesn't offer the ability to monitor devices by groups, customers, or carrier to give an overall health performance of specifically-defined environments. That's where HelpSystems Intermapper could have done a better job. I would love to see advanced SLA monitoring and reporting in this solution. They already have a lot of ingredients. They already have SNMP polling. It is really about what people are looking for from SLA monitoring, especially someone who looks at the network topology. You want to see your endpoints. You want to see half of your endpoints by simply analyzing ICMP or SNMP-based availability of your endpoints. Having an ability to define your group and how you bring devices into your group would be a huge benefit.

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.

Quotes from Members

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

Pros

"It's a nice graphical interface, a nice map, that relates Layer 1 to Layer 3, virtually instantly, to the Helpdesk support staff. It provides a default place to get critical information so we can deploy our staff."

"The graphical alerting with the ability to obtain a quick overview of a monitored device is my favorite feature."

"The most valuable features are its: log history, real-time monitoring capabilities, accuracy - the number of false positives is very low, and the mapping features."

"It's all today portal-based which is a good feature for us."

"Right now, it is really a combination of network topology, network monitoring, and network analyzing, so, in my opinion, it is awesome."

"What is really cool about HelpSystems InterMapper is that because of its SNMP base, you can integrate all different makes and models on the same map. You, of course, can have more than one map, but you have an option to have visibility into the entire network from one centralized system. You can monitor IPs, routers, radios, DC power plants, and UPS. You can do it all from one network management and monitoring solution. That's what really makes HelpSystems Intermapper great. Another great thing about HelpSystems InterMapper is that you can really bundle different probes under one device. You can have a bundled device. You can monitor the physical status of a host based on the IP availability. You can also monitor services and actually see if anything happens. You can quickly determine whether it is the application layer, host layer, or network layer. HelpSystems Intermapper gives such a unique representation of a network. Ever since we started using HelpSystems InterMapper, we don't have to document everything in a detailed format and store it somewhere. Right now, it is really a combination of network topology, network monitoring, and network analyzing. So, in my opinion, it is awesome. When you have your SNMP topology defined, you don't require a dedicated NMS engineer to manage your system, which is another great thing about HelpSystems InterMapper. I see how our operators get so excited by having the ability to map a device or interface and connect interfaces together. HelpSystems InterMapper is also very operator friendly; not just user friendly, but also operator friendly. This is a unique feature, and it works really great."

"Put Intermapper in as your base to start from, hands-down."

"The solution has a couple of features which are really interesting; it's not a fancy or expensive solution but we wanted to have a cost effective one and it's doing its job pretty well."

"Nagios XI is an outstanding network Monitoring tool, which can be tweaked to suit any environment and it is a good solution for business looking for remarkable features at zero cost."

"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."

"I can monitor a phone on a desk to very big servers of any company."

"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."

"The most useful aspect of this solution is the ability to customize it for the client agent."

"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."

"An excellent solution that is easy and intuitive to implement."

"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."

More Nagios XI pros

Cons

"I have seen instances where Intermapper does not seem to recover from network changes."

"It's a smaller solution so tools are not as advanced as you would find in a larger solution"

"I'd love to see more of the network management side of it coming back into it."

"They can do a better job with SLA reporting. It does some basic reporting, but it really doesn't offer the ability to monitor devices by groups, customers, or carrier to give an overall health performance of specifically-defined environments. That's where HelpSystems Intermapper could have done a better job. I would love to see advanced SLA monitoring and reporting in this solution. They already have a lot of ingredients. They already have SNMP polling. It is really about what people are looking for from SLA monitoring, especially someone who looks at the network topology. You want to see your endpoints. You want to see half of your endpoints by simply analyzing ICMP or SNMP-based availability of your endpoints. Having an ability to define your group and how you bring devices into your group would be a huge benefit."

"I'd love to see more of the network management side of it coming back into it. If we were able to run scripts to bounce ports on switches, that would be great. It's asking a lot, but it's actually very doable because I do it through scripting into other products. If we could incorporate that directly into Intermapper, that would be fantastic."

"It's a smaller solution so tools are not as advanced as you would find in a larger solution"

"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."

"Backup mechanisms and some kind of templating system for dashboards are needed."

"We'd like to see more integration capabilities."

"The GUI could be improved."

"The scalability of Nagios XI is scalable. However, it is not easy to do."

"Nagios XI isn't really good for scaling, in my experience."

"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."

"The tool's AI model needs to be fixed."
