Likelihood to Recommend I would recommend all system administrators use some form of network monitoring if they are not already doing so, and I'd definitely recommend people consider OpenNMS if they're shopping around. Small businesses will benefit from the low-cost of entry (it's free!), whilst getting all the enterprise features. Larger businesses can benefit from paid support plans.
However, there's no getting around the fact that you will require some advanced networking and sysadmin knowledge to get the most out of OpenNMS, or at least, be prepared for a steep learning curve. If you don't have the resources to devote this time initially, you may struggle.
Read full review 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.

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. Read full review Cons We've had a few issues with delayed alerting. I haven't quite figured out how to make topologies work yet, but I haven't spent a ton of time on it either. We've also had a bit of trouble importing some MIBs, but that usually boiled down to working with the vendor to make sure we had the right MIBs and dependencies.

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. Read full review Usability Navigation is clean and neat.
Read full review Support Rating I still rate OEM as a must-have tool for central management of Oracle fleet. The pros and cons of the product is prominent. Meanwhile, I also acknowledge that OEM was design about a decade ago. At that time, it did not have the landscape we have today, such as cloud, DEVOPS, machine learning, etc. I hope in future releases, the design will incorporate those features.
Read full review Alternatives Considered OpenNMS's more attractive GUI and its price break were the main reasons our company chose to explore and use this product. However, it never managed to actually replace
Nagios which had a much more established hold within the company. Perhaps we were over-monitoring, but our company claimed a $100k loss per hour of downtime.
Read full review 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.

Read full review Return on Investment Initial adoption required quite a lot of resources and time to get everything right. Totally worth it for us; just be prepared for a gradual process that will get better and better with time. Once setup and running smoothly, it provides us with all the reporting we could hope for, at near zero cost. With OpenNMS, we're able to offer a much more reliable service to our customers, and spend a lot less time dealing with issues.
