Chose Icinga
PRTG was the solution that was implemented before. As Icinga is Open Source we saved the licensing fee, as we ran out of free checks. I also had knowledge in Icinga so we switched over.

Nagios is inferior to Icinga in my opinion, as Icinga has the better Web UI, which I use the …
Chose Icinga
Installation and initial configuration is straight forward. However the system can grow in complexity very quickly, if not managed correctly.
Chose Icinga
Icinga was initially a fork of Nagios. Over time, the configuration language was replaced with something more programmatic. This configuration language is one of the big sellers of this product. It allows flexible, quick configuration of large sets of hosts and services with …
Chose Icinga
While Icinga holds its own against old stalwarts like Nagios and Zabbix, it simply can't compete with the new generation of SaaS service/server monitoring software in terms of ease of use, feature-completeness, integration with things like Cloudwatch, CloudHealth, New Relic, …
Chose Icinga
There are two main competitors of Icinga in my opinion, Nagios, and NetFlow based monitoring solutions. Both are good, Icinga, is a more refined version of Nagios with a much better API and backwards compatibility to the platform. If you are running Nagios, you can transfer …
Chose Icinga
Icinga is better than Nagios because of its nicer user interface. New Relic can monitor CPU/memory and disk usage, but it's more of a performance and application troubleshooting tool rather than monitoring.
LevelBlue USM Anywhere
Chose LevelBlue USM Anywhere
We have not used any competitive products. The ones we looked at when we made the initial purchase were too expensive.
Chose LevelBlue USM Anywhere
It unifies a lot of network tools in one product including Nagios.
Chose LevelBlue USM Anywhere
AlienVault’s strength is that it is highly capable SIEM with a nice feature set. Unified Security Management Platform comes with more advanced features in performance, administration, reporting, and technical support. It offers greater coverage against attack with more than 600 …
Chose LevelBlue USM Anywhere
The AlienVault Unified Security Management is much more affordable than the above mentioned products. Installation and configuration is simplistic and provides much of the same dashboards and raw log viewing. The AlienVault USM does not include extra parts such as specific …
Chose LevelBlue USM Anywhere
When comparing the differences between all these programs we noticed that AlienVault Unified Security Managementblew the competitors out of the water not only in pricing but in so much more. The features that they were offering were not only amazing selling points but some of …
Chose LevelBlue USM Anywhere
I've evaluated HP ArcSight but it's very costly.
Nagios Core
Chose Nagios Core
We selected Nagios because of the size of its community. We've used some of the others in the field over the past few years, Nagios had the best features out of the box coupled with it's following made it an easy selection.

Icinga GmbH
Icinga is a world-class monitoring system. It can be used for most general monitoring situations. It is not a silver bullet, however, and there are instances where domain-specific monitoring systems are necessary. However, the output from those monitoring systems can be funneled into Icinga as a central monitoring and alerting system.

At this point I'm saying a 4. While the marketing material make it appear to be easy to use and it was relatively easy to set up, as previously mentioned, each event description is based upon the individual asset making it nearly impossible for the administrator to be a SME for each asset. For example, if one of the assets reporting is a router, the administrator monitoring alerts would need to know what the various events are that can be triggered as an event for the particular router; however, if the asset is a workstation, the administrator would need to know the various events that are triggered for workstations.

Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.

  • AlienVault USM is simple and easy to deploy. Sensors can be deployed in as little as 15 minutes through the setup wizard.
  • The USM UI is easy to understand. I've trained multiple analysts who are able to perform their duties on their first day, in part because of USM Anywhere's ease of use.
  • Top-notch built-in compliance templates and reporting features.

Cons
Icinga GmbH
  • High learning curve, setting up Icinga from scratch can be a bit of a challenge starting out.
  • If the io2db process fails you UI stops updating, which can be very frustrating.
  • There is no simple mechanism for adding new hosts and services through the web UI, it's all very config-file based.

  • Personally, I've wished I could purchase a service that would configure AV for my environment. I get a lot of traffic on a daily basis and I almost need to hire an analyst that just works on AV.
  • Some of the filters when looking for a specific alert aren't that easy to use.

  • Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
  • Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.

Icinga is a solid solution which does everything it promises. It is backwards compatible with most Nagios instances, making the transition very easy. Once you get the hang of installing new plugins and editing configuration files expanding its monitoring capabilities are easy.

The centralized logging and retention for PCI compliance was our main driver, and it is meeting that need. Otherwise there has been enough frustration with the lack of documentation and the need to customize through the CLI that I would be open to alternatives.

Once you are able to navigate the different panels, finding what you need is quite easily. Before getting used it it can be a bit of challenge . Each panel is quite well laid out and the filtering search capabilities are quite strong.

The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.

We do have issues with maintenance on the AlienVault USM as the disk fills up from time to time with other data sources. Sources for scanning logs and net flow data isn't calculated in regular disk maintenance and can easily fill up our disk if we do not keep an eye on it with some custom Nagios plugins. The system does properly trim logging data from logging sources properly.

With the latest release of AlienVault USM overall performance has not been an issue. We have noticed single source events per second does not scale well with the overall system. 2,000eps on a vmware system with a single source produces delays of up to an hour for us. Pages, reporting and even raw log searches are rather quick though.

It was very well organized and helpful in using the product to the fullest extent. The instructor allowed time for folks who were involved with managed services to receive tuning tips in order to better support their customers. In addition, the course materials were automatically updated when the new version came out.

AlienVault USM was a very simple to implement and get up and running. We started with a trial version and had that up and going within an hour of receiving email instructions from the sales engineer. We never had to contact support to get the system up and going. It was extremely easy to convert over to a full license once we started with a paid version.

Splunk's ES is a paid add-on on top of an already pricey product. Finding a MSSP that supports Splunk and isn't a 6 figure annual commitment seems unlikely. LogRhythm did not have a cloud-based solution when we were considering SIEMs. Fantastic product though and have a good MSSP base. Devo did not have a MSSP partner base when we looked. Their product is fantastic too. AlienVault USM has good partners to choose from as well as an affordable cloud model, that's why we chose it.

Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].

Scalability
Icinga GmbH

The AlienVault USM is not very scalable. Some scalability can be achieved by installing additional sensors, but this only offers 500eps per sensor and is still overall limited by the installation type of VM or physical. We have also noticed the EPS (events per second) is rated overall and not towards a single source. A single source on a very healthy VMware partition tops out at 2,000eps for us, no matter how we configure it. Maybe this is a problem of the 5.2 release?

Return on Investment
Icinga GmbH
  • With one check you know which applications are faulty e.g. after an upgrade. Which is big time saver
  • You easily detect outages ion the applications so that your customer ideally does not even realize there was an outage.
  • Detect if the environment does deliver the same result as in the same time as before to detect shortages.
  • Additional information when debugging. Saved us several hours where we could simply point to a database which was slow.

  • Once you hit the 150 asset mark, you have to jump to their unlimited license. There is no middle ground. We were only 10 or so assets above the 150 so we had to chose to either not monitor those assets or pay the price of the upgrade.
  • AlienVault brings all the information to one place which makes it much quicker to track down problems.

  • With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
  • You can set up as many alerts as you want without incurring any fees.
