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.

Oracle Enterprise Manager

OEM is very well suited for all Oracle products, especially Oracle databases and Exadata machines; even not Oracle hardware, it is very good and displaying high level details.OEM is not well suited for older hardware vendors like AIX, HP-UX, DEC/Digital, Microsoft (sql server). This is a big negative as most large companies have a heterogeneous environment with many different vendor hardware and (database) software products.

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.

Oracle Enterprise Manager

  • Database status. Being able to see which databases are up/down, at a glance, allows us to quickly react to issues.
  • Reporting. We report on last backups, daily status, a host of metrics, and compliance levels of all our databases. With reporting we come into the office with a set of "status" reports and we know instantly if a database has issues.
  • Metrics. We have a number of KPI's and SLA's we need to meet. Metrics applied to the databases allow us to stay on top of those requirements as well as fix common issues without a DBA needing to log in to assess the issue.

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.

  • We also use OEM to monitor SQL Server. However, OEM only provided limited features for SQL Server. It would be nice if we can schedule backup jobs for SQL Server in OEM.
  • The ability to run SQL queries. You can't run queries in OEM. I have to go to SQL Developer or SQL PLUS to run. queries.

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.

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.

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.

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.

Oracle Enterprise Manager

Toad for Oracle is more suited for individual users who have a strong focus on database development, and it is not as comprehensive as Oracle Enterprise Manager. While it is quite decent in logical database layer tasks, such as schema objects and SQL, it lacks visibility into host level and I/O layer performance stats.

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

Oracle Enterprise Manager

  • You are practically blind without OEM. There are other tools available but are expensive and negatively impact database performance.
  • If a bug hits OEM and it skips monitoring or doesn't catch something, it can have extremely negative consequences.
  • Being able to deploy scripts through OEM has replaced thousands of hours of work.
