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.

An affordable product with great integration capabilities
Plixer Core Platform is a valuable feature and a good software. Plixer Scrutinizer uses NetFlow analysis to monitor whatever is there in a network. Price-wise, Plixer Scrutinizer is not an expensive product. Basically, Plixer Scrutinizer is an affordable product. Plixer Scrutinizer is a tool that allows for customization, especially in scenarios where customers need new product features. Plixer Scrutinizer is a tool that can integrate with any other brand or product in the market, so it is not an area of concern.

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 monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"The solution's most valuable feature is its simplicity."
"The alerting system is very effective."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"Nagios XI is stable."
"They have very accurate and fast support."
"We have had many requests to understand in the network which devices are connected to others. Most people don't have this information or are able to establish a map of data flow everywhere around the network. Scrutinizer can really help with this. We are using it to understand who is talking to what, how, and which protocols can help us to improve security and analyze flow."
"I really feel, after reviewing three at one time and knowing some other ones, the bang and performance for the dollars, and the capacity and the flexibility; it's really second to none in those situations."
"It helps us determine what is going on with our Internet and who is hogging it all up, and if we get a real high throughput or a throughput that's going over and getting dropped fairly quickly, we can tell who (or what device) is consuming that traffic."
"The most valuable features of the solution are the ability to track what a device is doing and to go back historically. It is also able to go down to, and identify, very low levels of traffic."
"The solution helps to enrich the data context of our network traffic. It allows me to see what applications are most in use on a slightly historical basis, going back a day or week at tops. It allows me to tune QoS or traffic shaping around what's being used. It saves me from having to unnecessarily upgrade, if I don't need to."
"It's agnostic as far as what your network gear is. As long as it supports an sFlow, JFlow, NetFlow, some kind of flow monitoring, Plixer will support it very well."
"One feature I found most valuable in Plixer Scrutinizer is the very extensive reporting. Reporting is very flexible, though sometimes you need a little bit of support from Plixer Scrutinizer to create custom-made reporting in a very short time. Reporting is a very strong feature of the product."
"If you really want to know what's happening on your network, this is one of the best tools that you can use."
 

Cons

"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"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 part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"It would be useful if there was a way to back up the configuration information."
"In Plixer Scrutinizer, scalability is an area with minor concerns where improvements are required."
"They're working on the security areas, so it can provide more insight."
"We couldn't get it set up properly."
"Data retention needs improvement. Data retention is a thing where we are looking for a better way to collect flow data for a longer time to do forensic research on security incidents. By default, data retention is quite low. We need detailed data in safe storage for a longer time, e.g., for a couple of months. An improvement would be a way to export data into a secure long-term storage."
"It would be useful if there was a way to back up the configuration information. E.g., if you wanted to deploy a new instance or disaster recovery, you could quite easily deploy and restore the config, as opposed to having to restore all the NetFlow data. If there was just a button that said "backup config information", that would be good."
"Though Plixer Scrutinizer has network detection and response, it's an area that needs just a little more rounding out. Another room for improvement in the solution is its lack of SaaS offering which some customers were looking for. My company deals in small to medium businesses, mid-market, and some customers wanted the SaaS feature which Plixer Scrutinizer doesn't offer. What I'd like to see in the next release of the solution is for it to have a SaaS offering because my company also deals with educational spaces and smaller businesses that just don't have the staff that can implement this. If there's either a managed service or SaaS-based offering to just make it a little easier for those types of customers, it would be a great addition to Plixer Scrutinizer."
"From what I understand it is that the solution is not very scalable in a high volume traffic environment with a large number of flows."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is an expensive solution."
"Licensing costs are reasonable."
"The pricing is high with separate licensing for the product and support."
"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 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."
"We pay our one-off cost for the licenses, per device, in blocks of 50. And then we pay an annual maintenance fee of about $15,000 Australian, which is, at this point in time, about $9,000 US, for those 250 devices. The upfront costs for the 250-license use, were about $50,000 Australian, which is about $32,000 US."
"It's about €10,000 a year for initial license and yearly maintenance costs. In addition, the hardware costs are about €10,000 once every five years."
"Our entire solution, amortized over five years, is in the vicinity of $40,000 to $50,000 a year."
"We just renewed. The pricing is 5,000 euro per year. This is the final price. All tax (20 percent) is included."
"There are no extra costs. It's about $8,000 a year. The bang for the buck (cost) is definitely a plus."
"I rate Plixer Scrutinizer's price a three on a scale of one to ten, where one is low price or affordable, and ten is high price or expensive."
"We recently bought a license upgrade, so we will integrate more exporters. We upgraded from a 25 exporter license to a 50 exporter license. Therefore, there will be more flows, and this will be an extension. I don't know when we will purchase a faster server, because the server that we have is quite new."
"We have increased the license over time. We have added more licenses as the network has grown."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
