Offers effective monitoring of resources but lacks the ability to connect to an AWS instance and write custom queries.
We use it mainly for monitoring, including CPU, memory, and disk space, and for troubleshooting purposes We've set up alerts to notify us when performance deviates from the baseline we've configured for each resource. So, whenever that happens, we get an alert and can investigate immediately. So,…

Performance issues have been identified and monitored effectively during peak hours
The weaknesses I would like to address in Oracle Enterprise Manager involve the dealing of Grid Infrastructure. Oracle Enterprise Manager's handling of Grid Infrastructure needs some improvement. I want to see additional features in the future that deal with security in relation to Oracle Grid Infrastructure. I want to improve these two components.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"One of the things that it is used for is to detect anything that could possibly cause our systems not to function well, and it has helped us to determine that before anything has actually happened."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"We're able to diagnose issues prior to their actually becoming issues. Without the alerting, we wouldn't have a clue as to what was going to happen. With the alerting, it gives us a heads-up that a specific threshold has been met, and we need to take specific action."
"The best part of SQL DM is the ability to customize alerts and counters. This allows our team to find an issue then alert on the issue at a granular level."
"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Overall, it has allowed us to do more with database management and run more databases on a given server, because we're able to isolate issues quicker and take the proactive steps necessary to correct them."
"The most valuable features are disk space projections for planning, and also the Snapshotting ability, to look back in time, to see what was going on the server at a particular time. It's basically the output of an sp_who2."
"In my experience it seems the best tool for monitoring Oracle products, ranging from software to hardware like the engineered systems (e.g. Exadata)."
"When looking at, and selecting, a vendor to buy from, the most important criteria I look for are the stability of the product, scalability, and technical support after that."
"We are going to minimize the downtime; if the system is down, it will page us and we are going to get to that issue, and it also tells us when the system is running slow so if some people are experiencing performance issues we can see that, and it is a very useful graphical user interface for the management to understand."
"If you run Oracle Products from Oracle OVM, Oracle Database, Web Logic, etc. Oracle Enterprise Manager is by far the best way to provide a single console and monitoring and alerting solution."
"The look and feel I think. Fast and compatible."
"I think what I really like in this product is that DBAs and my management development team don’t have to sit and manually write queries."
"One can think of Database Consolidation Workbench OEM 13c as the “Holy Grail” of Database Consolidation."
"The ability to scale is excellent."
 

Cons

"I would absolutely love to create customized dashboards but, unfortunately, they don't provide me the information that I need to create the report. The report I need is the detail or the transaction detail that's happening on those Snapshots. I'd like to be able to go back through time and search for things. I don't have that functionality, which is very disappointing. That's pretty bad and frustrating because I could query it and find out so much information about what's hitting my environment and when, but instead, they want control over it and to not give me that information. So it's encrypted. I can't pull it out and that is really bothersome."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"I'm going to do an upgrade which may resolve my issues, but one area for improvement is its ability to handle the amount of data that we collect with it. We're likely one of the largest installations, with over 300 servers being collected with this product, and sometimes there are gaps. That would really be my only concern, in terms of how the data is collected and stored, for consistency."
"Scalability is what I mentioned earlier, regarding room for improvement. It doesn't seem to scale out to an environment as large as ours, with just a single monitoring server."
"With basic SQL training in my history, I've found at times I needed to Google SQL counters, for example, to understand what was occurring or how to configure SQL DM to be useful."
"Reporting and overall analysis of data gathered from SQL Server."
"It would helpful if SQL DM could mark when changes are made within the program."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"I don't think anybody can walk on water. Software is buggy and that's the nature of the beast."
"The issues we've had with Enterprise Manager go hand-in-hand with our issues with SOA Suite. There are performance issues that we see tied to SOA Suite and the B2B functioning, all of which impacts Enterprise Manager."
"BI Publisher integration; EM CLI commands."
"It's quite user-friendly when integrating, but when propagating user access and agents, it's not so intuitive."
"OEM needs to be a little bit faster."
"The fact that Oracle Enterprise Manager is an expensive solution is a matter of concern and needs to be considered for improvement."
"It would be helpful if OEM is integrated with OBIEE reports and free report viewer without a license."
"One of the biggest issues, especially for 12c grid control, is the performance; to be able to monitor and find the root cause of performance issues immediately, in real time."
 

Pricing and Cost Advice

"We were upgraded to Premium Support without their actually asking us, when we were quoted. Then I asked for Standard Support and that they had to re-quote us that. But they don't do that by default. They upcharge you by default, which I didn't think was very nice, without even asking."
"The pricing is reasonable, it's comparable with the competitors."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"The product’s price is reasonable."
"We are satisfied with the pricing."
"The license is good but can be improved."
"There are a few bugs with the software which require opening SRs with Oracle Support which contribute to the day-to-day cost. Perhaps 8 hours per month is spent dealing with support, just as a rough guess."
"The solution is inexpensive to purchase."
"The product is highly-priced."
"The product is very expensive."
