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

"The ability to go back and look at historical data is the most valuable feature."
"Baselining our SQL Servers has made a huge impact."
"Memory and CPU utilization features are good."
"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."
"Ability to identify bottlenecks, deadlocks and slow running queries and run monthly and daily reports."
"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."
"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."
"The masking features are good, and many new options and features are available in OEM for masking when compared to other tools."
"The most valuable features are security and speed."
"SQL Tuning Advisor, ADDM, Top Activity, ASM Space Manager, Incident Notifications"
"With standardized monitoring templates and incident rule sets, we are able to consistently monitor, manage and alert all DBAs in each group to the same level SLA for our customer's needs."
"I like the performance tuning features, particularly since it gives me a good glimpse of what has been happening."
"I have found the uptime of all of our systems to be most valuable with this solution. This is important because we need to guarantee specific uptime and preventive maintenance. We need to know upfront if there are going to be any issues on the database so we can proactively solve those."
"Initial installation of 12c OEM is convenient and straightforward."
"Excellent product for enterprise monitoring: The tool is able to monitor several other database products across various OS platforms."
 

Cons

"Some more granularity in alerting."
"Tech support has been okay, not that great, but they made sure that we got what we were looking for."
"Reporting and overall analysis of data gathered from SQL Server."
"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 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."
"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."
"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."
"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."
"One of the drawbacks that I don't like is, quite often you'll see that the agent will show a status of Pending."
"In a large organization with large number of targets, managing systems on an individual basis can be time consuming and difficult."
"I would like to have more details and privileges. I would say more grantable and obtainable privileges are needed."
"They should improve the hover text context."
"I've had problems with its reliability and speed. Sometimes even giving it a large amounts of software and hardware to run on, it can still be sluggish and fail to respond as quickly as you would think."
"Customer service: Fair, when needed."
"Sometimes it will take some time to open forms, so I feel it should be a little bit faster."
"Customer Service: 2 out of 5. I often choose to open an SR as a last resort."
 

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."
"It is part of Real Application Testing, so no new investment is necessary for clients who already are already using RAT."
"The basic functions are free. You only pay license fees for advanced features."
"The licensing is the responsibility of our customers."
"We are satisfied with the pricing."
"The product is highly-priced."
"Oracle Enterprise Manager is a free-of-cost solution. Oracle Enterprise Manager can be expensive only if you go for its licensing part."
"Be careful to only enable the packs for which you have a license as this is an issue we see time and again."
"The solution is free."
