IDERA SQL Diagnostic Manager for SQL Server vs. SolarWinds SQL Sentry

If you have several SQL servers and don't have a lot of time or resources to constantly monitor them, SQLdm will be very helpful. For one or two servers, it might be overkill. All of our servers are virtual, so having a tool that can monitor host metrics as well as guest metrics is a plus as well.

This solution is perfect for a team with a large server count and, at least, moderate experience supporting a SQL Server environment. If the environment is smaller or the team has less experience working with SQL Server performance tuning methodologies, then the tool may be overwhelming for the users.

• Database query optimization.
• Monitoring of databases in real time.
• Performance analysis and trends in the database.

• The Top SQL functionality has been extremely useful for identifying poorly performing queries by resource consumption.
• The flexibility of creating your own Advisory Conditions has allowed us to integrate our custom internal alerts into a centralized dashboard and alerting platform.
• Being able to highlight any chart on the dashboard and then tool-matching that window across all the other charts makes it much easier to correlate the different performance metrics against each other.

• Windows client has some issues. When you have small time intervals for your data collection, it can cause the client to become unresponsive and require you to restart it.
• It takes more time to get the web client running than it does to get the windows client running.
• The visualizations have been the same for the last eight years--could use a little bit of a refresh.

• Tuning advice: With all the graphs and data available, it's not always easy to determine the best thing to do. I'd like to see SentryOne provide some best practice analysis based on the historical information collected for the server being looked at.
• They could add help tips or links to help documents, when you select a graph on the dashboard. Inexperienced users tend to put blinders on and focus on one thing when they see a high counter or something out of the ordinary. It would be very useful to include a link that provides underlying help. The link would provide an explanation of the counter in detail and offer possible explanations as to why the counter is off.

Absolutely. SQL Sentry is an absolute must have for any company with a SQL Server estate. It provides a force multiplier to effectively manage SQL Server, and the feature sets are second to none. The support and expertise at SentryOne is incredible. They are very supportive of both the platform users and helping your business with the product

I accept that the flexibility of the alerting comes at a price. Other than the alerting SQL Sentry's interface is intuitive. Connecting to a new SQL instance, given that all the needed ports are open in your firewalls is straight forward. Reviewing the performance and queries for an instance is available in with a right click. As you dig in new tabs are created to present the detailed data. I find the ability to filter and rollup metrics on a query very helpful in dealing with the "it's running slow". You can easily compare the metrics of run times for the same query to let the user know, it's probably data your doing a billion reads instead of the usual 100 thousand.

The system is working perfectly in capturing data, but we do experience issues with SQL Timeout when viewing results in the remote clients. This may be due to the fact that our monitoring service is consuming most of the CPU, and it is the same server that is hosting the SQL Repository. We could probably fix the issue by separating the SQL instance from the monitoring service.

In most cases the pages load very quickly. In our particular case, we need to do some movement of services to separate our monitoring service to separate infrastructure from the repository. When we first started with SQL Sentry on 5 licenses, we did not have any issues. Since we have now grown that to 25, we are experiencing some challenges. We do not believe this to be a tool problem

Was suggested that we install the process monitors on a dev or qa database server, but we found it more useful to create an IT db server and put it there (along with a few other apps that we use for monitoring).

IDERA SQL Diagnostic Manager for SQL Server is an excellent tool, however I think Solarwinds Database Perfromance Analyzer is a slightly stronger more well rounded product

SQL Sentry offers more features and is customize-able to fit our business needs. It has more centralized management and support. The company's technical support is also top notch. It is also worth mentioning that SentryOne Team Blog is an excellent source. One can find lots of valuable troubleshooting skills on the blog site - very educational and informational.

We are running 25 instances through a single monitoring service and it is able to keep up. We are finding that this many instances in our environment is about as many as can be handled. We will need to deploy additional monitoring services. Luckily, there is no additional licensing costs to deploy additional monitoring services. For us, it's just an additional Azure VM.

• It saves me a significant amount of time each week, freeing me up for other important tasks. I couldn't possibly monitor each server individually to the extent that SQLdm does.
• With the wealth of information I can get to easily, I can be more proactive in taking care of my environments rather than reactive. The times when other people notice something happening before I do are few and far between.

Incentivized

• Better customer service as it alerts me automatically to loss of service issues so I can react and either get things fixed before it impacts the customers or to let my management know as soon as possible
• It helps me find expensive SQL so our customers get better performance and we make better use of our resources
