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

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

"The solution is very complete and mostly easy to manage."

"This is probably the greatest advantage of Nagios - it can be customized to a degree to suit your monitoring needs."

"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."

"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."

"Nagios allows IT staff and end-users to see the status of critical services on the network and can alert and notify selected users if critical services fail, reducing the mean time to recover."

"This is a fit for purpose product which means that if you have a definite list of requirements and are not willing, or unable, to spend money on big enterprise tools, then Nagios is a tool to go to."

"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."

More Nagios Core pros

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

"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."

"If you have a large network then this product is totally invaluable."

"We didn't experience any bugs."

"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."

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

"For security purposes, it is really a very powerful product."

More Plixer Scrutinizer pros

Cons

"We're using the free version, which limits us in terms of the things that we can do. If we had the paid version, a lot of our issues would probably go away. For example, we can't isolate instances that are being built or updated with the production ones. When they're being built, on Nagios, they're showing in red. It'd be nice to be able to partition those off until they're all green, and then we can bring them into the environment. This is probably because we've got the free version and not the paid version. If we went for the paid version, it would probably allow us to do exactly what we want to or remove the restrictions that we have, but if we are able to isolate instances in the free version, it would make life much easier."

"Nagios Core can improve the graphical interface, it would make things a little easier."

"Some of the reporting functionality is a bit basic and configuration is a chore although by the use of NagiosQL this can be made a lot easier."

"It would be nice if the company offered a sales or contract manager that was dedicated to our company so that we would have some sort of link to Nagios, and if we had issues or questions, we'd be able to contact them directly."

"Lessening the price point would be an improvement."

"The alerting mechanism in Nagios Core could be improved."

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

"The mapping is a little hard."

More Nagios Core cons

"I wish the reporting side was easier to work with, but it does a decent job."

"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."

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

"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."

"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 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."

"The reporting structure, the front-end GUI, also needs some work. It needs some getting used to. It works fairly well, but it's a technical tool rather than a user tool. You have to understand the structure of the databases before you can really use it."

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

Pricing and Cost Advice

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

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

"The product is cheaply priced."

"Nagios Core is free to use."

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

"We are using the free version."

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

"Lessening the price point would be an improvement."

More Nagios Core pricing and cost advice

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

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

"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 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."

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

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

"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."

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