We performed a comparison between IDERA SQL Diagnostic Manager for SQL Server, Oracle Enterprise Manager, and SQL Sentry based on real PeerSpot user reviews.
Find out what your peers are saying about Oracle, Quest Software, SolarWinds and others in Database Development and Management."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."
"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."
"Memory and CPU utilization features are good."
"The ability to go back and look at historical data is the most valuable feature."
"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."
"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."
"This solution allows us to quickly drill down when there are issues."
"The most valuable feature of the solution is that it is a very user-friendly tool."
"It is a stable solution...The initial setup of Oracle Enterprise Manager was straightforward."
"Oracle Enterprise Manager is a scalable solution."
"It is a good tool for monitoring databases."
"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."
"It is a comprehensive, end-to-end solution for managing database consolidation, something that has been missing and difficult to do."
"It can also help with capacity planning, sizing, and maximizing overall performance in a large scale environment."
"To be able to go back in history and find out what was happening at certain times is the most valuable feature of the product."
"This solution has identified blocking, deadlock, memory pressure, and high CPU consumption issues."
"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."
"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."
"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."
"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."
"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."
"Oracle Enterprise Manager's scalability is an area with certain shortcomings where improvements are required."
"The solution is considered expensive."
"The tool's pricing is costly."
"In my experience, the monitoring could be improved."
"I would say mostly backup and recovery, through the Enterprise Manager. Or any corruptions, to be able to fix them through Enterprise Manager."
"I would like to improve the cost."
"I would like to see better pricing."
"The product must improve its support team."
"There could be some more metrics on the high availability to let us know when there are issues synchronizing between the hosts."
"If we can get details on wait types from system views, it will help identify a more detailed root cause."
