Oracle Enterprise Manager vs. Percona Monitoring and Management (PMM)

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.

I suggest you try [Percona Monitoring and Management (PMM)] at least once. Afterward, it
will make you feel relaxed. It really works and gives you more than your
expectations. It is equipped with multiple latest and advanced tools that will
fully satisfy you. So obviously there will be no need to concern other devices. It is
an excellent data management solution and also it is the best monitoring device than
any other.

• 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.

• Measure the time and performance of queries made in a database
• Integration with tools like Prometheus with the aim of storing information based on time
• Monitor our databases in the cloud, as well as optimize the performance of the database, improving the usability of customer applications

• 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.

• Sometimes it creates problems while serving a huge number of servers but I am sure its efficient team will overcome this problem soon and with its rapid advancements there will surely be more latest and advanced alerting options.
• Truly speaking this is a great invention with very few shortcomings. I never face any dependency issues.

I am using PMM for a long time now and the Dashboard provides a great overview for general server health and law. You get to watch if there are many queries when you get a problem. Time-based analysis for MySQL and MongoDB servers to confirm that your data works as efficiently as possible. We could improve database performance significantly.

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.

Percona has a history of being good at providing really informative materials in form of blog post, documentation, webinars or conference presentations. T is also true to the Percona Monitoring and Management, you can find excellent source of information on their site or on the forum. Support tickets are also handled well.

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.

Vividcortex is nice but is costly.

Datadog loses for me on the UI front and, of course, it will be a charged product.

Percona Monitoring and Management (PMM) has been best blend of technologies and is supported by the Percona community very well.
