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

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

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

"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."

"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."

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

"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."

"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."

"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."

"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."

"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."

"I really found Nagios a perfect fit for us and a good product to work with."

"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."

"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."

"Nagios has good scalability."

"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."

More Nagios XI pros

Cons

"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. 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."

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

"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."

"The user interface needs improvement."

"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."

"I would like to see support for notification via SMS."

"Implementation on Windows was painful."

"Initially, we encountered problems during the setup as some errors were noted due to a few prerequisites not being fulfilled and having some configuration files to edit and plugins to add."

"The reporting structure could be more streamlined."

"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."

"The product does not have SAP monitoring."

Pricing and Cost Advice

Information not available

"Licensing costs are reasonable."

"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."

"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."

"Nagios XI is an expensive solution."

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."

"Nagios XI is open source."

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."

"As it is not an agentless tool, I think it is expensive."
