Nagios Core

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.

SolarWinds Security Event Manager (SEM)

It is well suited to monitor your Windows AD. You can get detailed login information and notifications like failures and lockouts. It also shows the IP address where it occurs so it makes locating the culprit a lot easier. It does well with monitoring for suspicious activity. It can alert you if It sees a client is trying to circumvent DNS so they can go through proxy avoidance tactics.

Pros

Nagios Core

  • Monitoring of services is one of the biggest benefits for our company. Being able to respond in a timely fashion keeps business smooth.
  • Hardware and device monitoring are easy to set up with proper parameters.
  • Notification to key staff to be able to respond quickly makes issues go away faster.

SolarWinds Security Event Manager (SEM)

  • SolarWinds easily provides the much needed visibily into changes in an Active Directory (AD) environment. Email alerting can be configured to alert a team if an account is locked out, disabled by another users, or if users and/or computers accounts are created.
  • SolarWinds allowed a searchable audit feature. Microsoft Windows can be configured to log many different parts of a system, but search those logs can be difficult. SEM allows you to search for specific users or events.

Cons

Nagios Core

  • 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.

  • Compared to other SIEMs, there are features that are missing. Machine learning, automatic event correlation, ability to correlate multiple sources together.
  • The UI is clunky, and the *New* event log analyzer page felt really disjointed from the rest of the product.
  • In my experience, the dashboards were almost unusable. They persisted across login per device, and even then they sometimes would reset and go back to the ''Getting Started'' look.

We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.

It is pretty likely that we will renew SEM when the time comes up. It is easy to use and maintain so there isn't much of a need to replace this product. It is also a pretty fair price for the capabilities provided by the SEM

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.

After learning best practices of the SEM it is fairly easy to use and manage. Just the initial configuration and revision process can take some time. After about a month of using the SEM, I was able to navigate through most aspects of it with no problems. It just takes some hands on practice to best utilize the SEM

I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.

Support for SEM is really good. For example, if the connector is not decoding the event correctly, SolarWinds will make a new connector to properly decode the event - this usually takes about two weeks. The support team is very knowledgeable about the inner workings of SEM and have full access to the system to resolve any internal issues.

Alternatives Considered

Nagios Core

I have been using Nagios for 10+ years, so I am very familiar with it. The learning curve with SolarWinds was more difficult for me to pick up than Nagios and it wasn't as easy (at first) to duplicate, edit, etc. in SolarWinds. I genuinely think Nagios is a great product for many reasons, one of which is the unbeatable price.

There may be more intuitive/automated solutions in the marketplace but because we already had a good relationship with SolarWinds, we decided to ultimately go with SolarWinds LEM. There are many resources available to help you make SolarWinds LEM work just as you need it to. It has never crashed or ran out of resources so we believe it is a good solid product.

Return on Investment

Nagios Core

  • Much better network device performance metrics allowing to troubleshoot and do before/after changes comparisons
  • Has helped us to integrate with our Service Management tool (through other 3rd party tools)
  • Important part of our overall network health dashboard providing granular details at the device level (not end-to-end performance)
  • Cost is very convenient

  • Faster turnaround when investigating access issues. LEM's search function allows you to quickly identify which ACL policy may be blocking a user's access - and as a result quickly resolve the issue.
  • Regulatory compliance. If you have regulatory compliance requirements for security monitoring, this product will likely check off a few boxes.
  • Stronger security posture. Not every company can afford a 24 hour Security Operations Center. Intelligent technology like LEM can help fill in those gaps to strengthen your security posture, and even allow for complex automated responses to threats during non-business hours.
