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

"There are several monitoring tools, but IDERA SQL Diagnostic Manager is actually better than other competitors."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"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."
"The ability to go back and look at historical data is the most valuable feature."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"Memory and CPU utilization features are good."
"SQL monitoring time has been dramatically reduced and our IT Infrastructure team has improved SQL maintenance and monitoring knowledge over time just by using SQL DM."
"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."
"I like the reports of Enterprise Manager, as you have a lot of targets and can create generic reports based on some metrics of those targets, which allows me to have some sort of place to check all my targets."
"One of the most valuable features of Oracle Enterprise Manager has been the preventive reporting capability."
"I like that it's stable."
"In my experience it seems the best tool for monitoring Oracle products, ranging from software to hardware like the engineered systems (e.g. Exadata)."
"Enterprise Manager comes with a suite of products that includes agents for setup, making it easier to monitor databases as well as servers and SANs."
"Query tuning, historical graphs, real time statistics on query usage, easy to find blocking or locking queries, easy to kill queries, easy to add new datafiles to tablespaces about to run out of space, easy to explore table structure."
"The product gives us as much control as we can have by providing a complete picture of the whole set of Oracle products."
"I recommend Oracle solutions like T5 Super-Cluster, T5-8 and Oracle Solaris 11 operating systems, as they are highly scalable and fault-tolerant systems."
 

Cons

"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."
"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."
"One thing I'd like to see is the ability to view the execution plan and have the system automatically recommend potential query optimizations, especially at the query level."
"We don't find that it helps us with performance monitoring and diagnostics. We find that SentryOne does that better. Also, in terms of alerts, we had to customize them dramatically so that we didn't get alerted on every little thing."
"Some more granularity in alerting."
"Reporting and overall analysis of data gathered from SQL Server."
"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."
"RMAN tools need improvement."
"I would say the footprint on the server. Also the GUI can be tricky."
"It could be faster; sometimes it takes a while to make the connection. Sometimes, it's complicated, too."
"OEM needs to be a little bit faster."
"One of the drawbacks that I don't like is, quite often you'll see that the agent will show a status of Pending."
"Metrics settings could be improved to be more intuitive. Installation process could be easier."
"It is complicated to run it on Google Chrome."
"They should improve the hover text context. This would provide assistance whenever a task is attempted by a DBA."
 

Pricing and Cost Advice

"The pricing is reasonable, it's comparable with the competitors."
"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 product is very expensive."
"Evaluate your requirements carefully. Elaborate DR and HA setup of OEM can become expensive."
"The license is good but can be improved."
"There is only the standard licensing fee. There are no other costs."
"The licensing is the responsibility of our customers."
"It's expensive."
"Initially, our deal was for three years, and we extended it to five years. Oracle solutions are very costly."
"The product is highly-priced."
