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.

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

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

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services."

"We mostly use Nagios Core to integrate with Python and Bash Script."

"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."

"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."

"Its an awesome product to use."

"Reliability Security Flexibility Functionality Availability - controllability anywhere and with different methods"

"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."

More Nagios Core pros

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

"We didn't experience any bugs."

"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."

"The reporting and generating troubleshooting reports would be the best feature; our host-to-host conversation reporting."

"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."

"My boss and I have been very happy with the product."

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

"Compared to other solutions, the functionality Scrutinizer delivers is better."

Cons

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

"A better UI for graphing would make it better. The present graphs are not very friendly and good to see."

"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."

"The initial setup was complex, mainly because it was in Linux and had many packages that we're not used to."

"Nagios SLA. I'm currently working on Nagios Digger, which has many code-level problems."

"The interface could be improved."

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

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

More Nagios Core cons

"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."

"Though Plixer Scrutinizer has network detection and response, it's an area that needs just a little more rounding out."

"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."

"They're working on the security areas, so it can provide more insight."

"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."

"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."

"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."

"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."

Pricing and Cost Advice

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

"Nagios Core is a cheap solution."

"We are using the free version."

"The product is cheaply priced."

"Lessening the price point would be an improvement."

"It's free."

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

"The Nagios Core (PNP4Nagios + Core) is free and can be setup by Netadmin within a few hours. The only additional cost is the cloud server."

More Nagios Core pricing and cost advice

"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."

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

"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."

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

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

"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."
