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.

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

"Key features include the GUI interface, its notification capabilities, and the real-time reporting."

"The most valuable features are the reports and the way it generates the report in a graphical manner."

"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."

"It has made the life of the network operations staff more proactive in managing the resources of the infrastructure. It prevents disasters long before they can take place."

"I like the way the solution sends alerts and how it keeps on escalating them."

"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."

"Monitoring with Nagios Core is helpful because it provides immediate alerts if something goes down, such as a server, or wireless router, or if there's a cable break. This allows us to respond promptly to any issues."

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

More Nagios Core pros

"We didn't experience any bugs."

"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 of the most valuable features of Plixer Scrutinizer is the reporting, particularly how easy it is to drill down into the reports. Another valuable feature of the solution is its overall visibility. It's great. I also liked Plixer Scrutinizer in terms of deployment time and that it's very simple to set up. Once you get the appliance set up and connected, the customer starts to see results immediately, versus other solutions where that could take a while."

"Plixer Scrutinizer is an affordable product. Plixer Scrutinizer is a tool that allows for customization, especially in scenarios where customers need new product features."

"Visualization of the network traffic is the most valuable feature. It allows you to drill into information quite quickly."

"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."

"The most valuable features of Plixer Scrutinizer are its ease of use, accessibility, and UI."

"It helps us determine what is going on with our Internet and who is hogging it all up. 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."

Cons

"The initial setup process could be easier."

"Bandwidth monitoring is the pain point for me because Nagios Core does not monitor bandwidth effectively like Cacti does."

"Cloud monitoring is an area for improvement because there aren't too many plugins available."

"It is a bit slow due to latency."

"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."

"The interface could be improved."

"Would benefit from aggregations if a particular server goes down."

"The user interface could be more interactive because it is pretty basic."

More Nagios Core cons

"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."

"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 was a price lift because previously the product was privately owned, and now there is some external capital in the organization, so pricing could be lower, though, for Plixer Scrutinizer, there is almost no competition at this price point."

"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."

"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."

"I wish the reporting side was easier to work with, but it does a decent job. I also wish the reporting side was a little more intuitive or they offered more reporting examples."

Pricing and Cost Advice

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

"It's free."

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

"Most the plugin features are free."

"We are using the free version of Nagios Core."

"Lessening the price point would be an improvement."

"It's free."

"The solution is expensive."

More Nagios Core pricing and cost advice

"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."

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

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

"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."

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

"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."

"Currently, the license for Plixer Scrutinizer is subscription-based and at a yearly fee. The price would depend on the amount of traffic you pull in. For example, there are several blocks from a 10K flow, a 40K flow, and a 100K flow, and based on the number of devices that you receive the flows from, that's the license, and it is not a per-interface pricing model, so that is a very strong, very competitive pricing feature of Plixer Scrutinizer. Licensing for the product is also not based on the number of storage, compared to some competing products that are priced based on the amount of storage you need, particularly based on the retention and the amount of data. Plixer Scrutinizer licensing is based on the device, and it's more in the direction of $10,000 because, with just $1,000, you don't have anything."
