Executive SummaryUpdated on Oct 10, 2024

Nagios Core and Plixer Scrutinizer both compete in the network monitoring category. Plixer Scrutinizer might have the upper hand due to its detailed network traffic analysis and structured support options.

Features: Nagios Core offers extensive customization, flexibility, and integration of plugins, focusing on infrastructure monitoring with customizable notifications. Plixer Scrutinizer provides comprehensive network traffic analysis, data context enrichment, and integration with security products for efficient traffic monitoring.

Room for Improvement: Nagios Core has a steep learning curve, complex configurations, and limited built-in assistance, affecting scalability. Plixer Scrutinizer could improve its user interface, reporting process, and handling of high traffic volumes for complex configurations.

Ease of Deployment and Customer Service: Nagios Core predominantly requires on-premises deployment demanding user expertise and relies on community support. Plixer Scrutinizer offers structured support, easing deployment complexities with prompt technical aid through its licensing options.

Pricing and ROI: Nagios Core is free but requires an investment in skilled personnel, delivering ROI by minimizing server downtime. Plixer Scrutinizer uses a sensor-based licensing model, providing cost-effective network monitoring with competitive pricing and advantageous trial periods.

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

"We can get real time statistics of our servers which improves our monitoring."

"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."

"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."

"Nagios Core is very configurable. Whatever you want, you can do it."

"Nagios Core integrates with tools like Splunk, Datadog, or Dynatrace. It is usually used as a feed to provide more technical information about devices or hosts to another system."

"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."

"The scalability of Nagios Core is very good, we can add as many hosts as we like, and we can work with the concept master and client, making it very scalable and easy to use."

"You should really try Nagios; it will help a lot and I have found that it is the best buddy for system admins."

More Nagios Core pros

"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."

"Scrutinizer does exactly what we need it to do; we're very happy with it, we're not looking to change in the short-term or long-term, and it's a product that runs without any issues and gives the information that we need."

"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."

"There are other tools out there that will do what Scrutinizer does. But what I have found with Scrutinizer is that it does it very quickly. I've taken 25 million individual data fragments from the different sensors, and it has graphed that and mapped it and presented a picture within 30 seconds. It has a very efficient database algorithm that I am really impressed with."

"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."

"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."

"The ability to view the status of the top-10 at a glance is helpful. We immediately know which link is over-utilized or heavily used... and it's all in real-time."

"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."

Cons

"The NetEase reporting structure needs improvement, especially the availability report, which is weak."

"The configuration and reporting modules need to be improved."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"I believe Nagios Core will need to provide an option for big data platforms in the future."

"The core version is no match for the XI version."

"When compared to earlier versions, it looks like 4.x has lost the statusmap.cgi module."

"Nagios Core could improve by adding a user interface. If you want the user interface you have to use Nagios XI."

"The core version is no match for the XI version."

More Nagios Core cons

"It would be useful if there was a way to back up the configuration information."

"The reporting structure, the front-end GUI, also needs some work."

"The visual acuity of how it presents data can sometimes be confusing. It takes a bit for people to spin up how to look at the graphs."

"There is room for improvement around the data that they have on the website about solutions... they should have more templated solutions on their website. Going out and identifying how to do RTP performance with a Cisco router, or how to do application response times in an Arrista data center deployment was where most of the work was... They should spend some more time documenting solutions and putting together white papers."

"We couldn't get it set up properly."

"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."

"For updating the Scrutinizer platform, when we have the actual data, it never happens in one day. Every time we have the data, we are obliged to install a new server in order to integrate the old data, and every time it has a problem. Most of the time, we were obliged to scrap all the data because we couldn't transfer it to the new server. So, it would be very good if they could improve this part."

"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."

Pricing and Cost Advice

"Nagios Core is free to use."

"We have saved a lot of time, money, and effort in reducing disaster times, which is owed to Nagios quick alerting."

"The enterprise version has technical support. The version we are using is free."

"The solution is expensive."

"Nagios Core is a cheap solution."

"I would rate the solution's pricing an eight out of ten."

"We are using the free version."

"We are using the open-source, unpaid version."

More Nagios Core pricing and cost advice

"Compared to some of the other tools we have, it's incredibly reasonably priced."

"There are no extra costs. It's about $8,000 a year. The bang for the buck (cost) is definitely a plus."

"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."

"We have increased the license over time. We have added more licenses as the network has grown."

"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 just renewed. The pricing is 5,000 euro per year. This is the final price. All tax (20 percent) is included."

"There is a recurring maintenance fee after the initial purchase or if we want the license upgrade."

"Our entire solution, amortized over five years, is in the vicinity of $40,000 to $50,000 a year."
