A solution to bring cloud security, billing, operations and management together. Rackspace Fabric offers a single platform for automated multicloud management. Service includes access to Rackspace cloud technology expertise, and provides a unified interface management for all cloud resources across Azure, AWS, GCP, and VMware, in a single, SaaS like operating environment.
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 am highly likely to recommend Rackspace Cloud Monitoring to a colleague. This is assuming they have a decent background in working on cloud servers. If you don't mind digging in yourself to solve problems, then this is a great resource. If you are just learning how to set up servers on your own, then I recommend at least hiring someone to help you use the service. With that being said, Rackspace makes it easy for people you may hire to seamlessly work within your account. They get their own separate developer account.
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.
Immediate email notifications: In case a service is down on our servers, we get immediate email notifications via rackspace cloud monitoring service. This helps us to know about the issues and we get in contact with support team to get it resolved.
Configuration on specific services: We can configure this monitoring on specific services. So for example if i don't want to get notified if MySQL concurrent users limit reached, then I do not need to configure this monitoring for MySQL. I can just use it whenever needed for defined services.
Group emails and technical contacts emails: The monitoring service can send email alerts to a number of email addresses. Primarily the ones who are added as a technical contact. It helps all people get notified about any issue.
Auto ticket management: Rackspace automatically creates a support ticket when a service is down and is notified by their monitoring service.
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.
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.
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.
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).
I also used Monitis as a monitoring service for our server. Rackspace'S monitoring sends immediate notifications while Monitis might take a couple minutes to understand if a service is down. Since Rackspace has their monitoring integrated with their support system, it helps us a lot and we don't need to call support all the time.
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.
