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

"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."

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

"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 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 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."

"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."

"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."

"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."

"Nagios is great for verify quality and quantity in a datacenter."

"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."

"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."

"Nagios is my favourite open source monitoring system."

"The overall performance of the product is superb."

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

Cons

"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 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. 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."

"There's no convenient way to manage notes as the only way is to manage them through the database."

"It can be quite difficult to know which drivers and agents to use when setting up."

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

"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."

"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."

"The Configuration Wizard needs improvement, because not all vendors are present."

"They need more documentation for the plugins."

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

Pricing and Cost Advice

"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."

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."

"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."

"Nagios XI is open source."

"Nagios XI is an expensive solution."

"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."

"Licensing costs are reasonable."

"The pricing is high with separate licensing for the product and support."
