IDERA SQL Diagnostic Manager for SQL Server vs SQL Sentry comparison

"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."

"Monitors and alerts on our mission critical instances in real-time on a 24/7 basis."

"SQL DM made troubleshooting much easier and allowed multiple people to look into an issue with confidence."

"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."

"Memory and CPU utilization features are good."

"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."

"This solution has identified blocking, deadlock, memory pressure, and high CPU consumption issues."

"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."

"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."

"They can improve checking the status of the CPU, memory, and IO utilization from each task."

"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."

"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."

"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."

"It would helpful if SQL DM could mark when changes are made within the program."

"If we can get details on wait types from system views, it will help identify a more detailed root cause."

"There could be some more metrics on the high availability to let us know when there are issues synchronizing between the hosts."

"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."

"It's fairly expensive."
