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.

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

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

"The solution is quite efficient."

"Nagios Core is a great tool for monitoring the infrastructure including MSM queues, and when we use the agent, we can add other things as well."

"Before we implemented Nagios, we did not know which servers were up or down until a customer told us, and now I can see trends over time and it gives me perspective of what needs to be improved so we are able to work proactively as opposed to reactively."

"We have the ability right now to see and create reports to tell whether or not we're meeting our SLAs on our production servers, through it."

"We are using Nagios Core on a VM and it's working very well, even though the specs of the VM are very low because it doesn't require much storage."

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

"Extensibility is good as this makes it easy to write checks on your own."

More Nagios Core pros

"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."

"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."

"The internal reputation of our IT to resolve historical bandwidth problems has 100 percent improved."

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

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

"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."

"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."

"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."

Cons

"Application level monitoring is limited."

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

"Nagios Core does not have a graphic display."

"Setup is bit complicated due to the large set of libraries it needs, but this may be because it's open source."

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

"I would like to see a much better Nagios Manager GUI that can support all type of configuration items, and advance search options."

"It would be nice if it was hosted in cloud. Also, they need to improve the graphs."

"I like to have the option to configure Nagios using the web interface."

More Nagios Core cons

"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."

"We were trying to set up some configuration, but it just wasn't quite working properly; we couldn't get it set up properly."

"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."

"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."

"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."

"There is room for improvement around the data that they have on the website about solutions."

"In Plixer Scrutinizer, scalability is an area with minor concerns where improvements are required."

Pricing and Cost Advice

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

"It's free."

"The product is cheaply priced."

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

"It's free."

"Lessening the price point would be an improvement."

"Nagios Core is a cheap solution."

"Nagios Core is free to use."

More Nagios Core pricing and cost advice

"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."

"The license is per device. We have 50 devices."

"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."

"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."

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

"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."
