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."
"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."
"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."
"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."
"Baselining our SQL Servers has made a huge impact."
"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."
"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."
"Using this product, we have improved our process for generating revenue and sending out invoices to our customers."
"In my opinion, without Enterprise Manager no DBA can do their job."
"The dashboards are great for gathering analytic information and seeing where the problems are."
"We need 99.9995 uptime, and Oracle Enterprise Manager helps us to achieve this goal with its superior monitoring and management capabilities."
"My advice to others is Oracle Enterprise Manager is a stable and scalable enterprise compared to the other similar solutions."
"The job subsystem, monitoring subsystem, alerting, grouping of targets, and reporting features are valuable to us."
"In my experience it seems the best tool for monitoring Oracle products, ranging from software to hardware like the engineered systems (e.g. Exadata)."
"I find it nice that OEM provides a graphical way to manage both our database and E-Business Suite."
 

Cons

"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."
"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."
"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."
"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."
"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."
"The initial setup gives too many user rights to the server, so you have to put a user that is part administrator's group - that's the preferred way - on each server, which is kind of a risk. You want to do least privilege and you're not doing that."
"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."
"They can improve checking the status of the CPU, memory, and IO utilization from each task."
"Customer service: Fair, when needed."
"It was a very, very complicated product to set up."
"Still, there are lot of improvements that need to take place."
"Setting up provisioning can be challenging. Also there are a lot of bugs and some specific to platforms."
"UI is the part that I like to see improved in the future."
"Yes, configuration is a pain."
"One thing I would like to see is the option of agent less monitoring."
"There are a lot of options; it takes time. I don't see anything like a dashboard or something similar."
 

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."
"The license is good but can be improved."
"We are satisfied with the pricing."
"Oracle Enterprise Manager is a free tool from Oracle."
"The product’s price is reasonable."
"The basic functions are free. You only pay license fees for advanced features."
"The solution is free."
"As far as I know, you do not pay for Oracle Enterprise Manager separately. You can use Enterprise Manager for free if you already have an Oracle license for your database."
"The solution is inexpensive to purchase."
