Oracle’s Enterprise Manager is an on-premises monitoring and management tool. The console is designed primarily to manage other Oracle products, it but can integrate to manage non-Oracle components as well.

Splunk supports IT operations analytics with the Splunk IT Service Intelligence premium offering, a software application available to subscribers to Splunk Cloud or Splunk Enterprise log analytics and SIEM platforms.
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.
Splunk ITSI is a great tool (and toolbox) for combining together numerous and varied monitoring regimes to bring more holistic analysis and reduce alert fatigue. By leveraging the Splunk ITSI service and KPI modeling regime, ecosystem telemetry can be turned into a more reliable, clearer, high-level perspective on the current state of your components and services.
Monitoring Templates: There are out of box monitoring templates for each target types, you can customize them or use them as it is.
Administrative Groups: This is a relatively new feature in OEM Cloud Control. This lets you create and manage your targets and monitoring templates smarter and with less re-work.
DB Monitoring: There are so many cool DB monitoring features and visual graphics, that it can be used by both DBA and functional people to see what's going on in the database.
Bugs. Every version we upgrade to has a number of bugs. Some stop us from rolling to production OEM (we have a sandbox OEM), some are simply annoying. If I could improve on one thing, it would be for better QA from oracle before releasing each version.
Flash. I'm told that they are moving from Flash to Jet in version 13.3 and beyond (we are on 13.2 currently). That change cannot come soon enough. The OEM pages load SO slowly due to Flash.
Hierarchy Groups. OEM allows five Hierarchy groups. A Hierarchy group allows a top down metric/rule roll out. However, they limit you to five. I'd like to see them open that up, so that we can have any number of custom groups.
We have replaced our monitoring platform with Splunk & ITSI, and with the success, it's seen at our organization thus far we would be hard-pressed to pivot to another tool. Frankly, our business partners and application teams love Splunk & ITSI.
It's great! It does everything and anything you would want it to do. It can monitor things which doesn't comes out of the box by adding plug ins to it, for example, you can even monitor Oracle GoldenGate Replication by adding a plug-in to OEM Cloud Control.
Splunk IT Service Intelligence (ITSI) is a platform with extended functionality and provides various functionalities which can be utilized to improve the efficiency and accuracy in analyzing the data and detecting the attacks.
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.
During POC, pre-planning, and implementation, we have had interactions with numerous folks at Splunk. Everyone from sales & engineering to markets analysts to specific IT component SMEs, and a small professional services engagement to get started. They have all been exceptionally helpful and go above and beyond the call of duty. They actively reach out to ensure success is being realized and find ways to help proactively, instead of having to simply open support cases with the vendor.
Being an Oracle shop using Oracle Database and MySQL, management console from Oracle was a better choice than IBM or Microsoft even though we do use Microsoft Azure and storage/servers from IBM (on-prem).
Splunk has raised itself as a platform not just as a tool unlike other products in the market. If I talk about Moogsoft it also has similar capabilities but Splunk ITSI has more visibility and its GUI is making a different impact on the users. ServiceNow and Splunk are equally capable products however Splunk seems to have more tech-savvy people tools than ServiceNow.
We are a 7x24 shop. Oracle Enterprise Manager Cloud Control helps us meet that objective by proactively warning us before issues cause down time. Things like disk space, archive log issues or temporary table space issues.
Spreading the use of this tool outside of the DBA group has allowed us to not hire additional personnel for those teams. Over time, as folks have retired from our operations team, we are not replacing them. Instead we have used OEM Cloud Control to automate tasks.
We also now have the tools to measure up-time by using specific measurements inside of OEM. This allows us to report real numbers to management.
Splunk ITSI has reduced the number of alerts exposed to our Network Operations Center by 100x while increasing the context around outages.
Splunk ITSI has increased the accuracy of our incident detection by leveraging the Event Analytics system to weigh the behavior of the many characteristics of each component together instead of independently.
Splunk ITSI has reduced our incident MTTR (mean time to restore) by detecting issues faster, presenting them more clearly, and surfacing the salient details about the underlying issue.
