SQL Server Monitoring and Troubleshooting Simplified for DBAs with SQL Sentry

Problem

Our organization has business-critical overnight processes that start at 4:00 AM with various feeds into a SQL Server data warehouse used extensively across our organization for every client interaction. These overnight processes have numerous variables, including data volume, erroneous data, and performance issues (IO, Memory, CPU). Our entire company depends on this data for decision-making throughout the day and expects systems to be available by 8:00 AM for smooth business operations.

Unfortunately, there are times when the overnight processes fail, resulting in two or three hours of corrections before the SQL Server data warehouse is operational. This raises concerns across the entire organization and shines a negative light on the SQL Server DBAs. How can the DBA team better understand the performance in real time to address these issues and proactively ensure smooth business operations?

Solution

This is the exact situation that Abdul Rauf experienced working for an investment bank. Abdul said, "I think I was one of those proud DBAs. I don't need a performance monitoring solution. These tools get various metrics out of the DMVs and Windows. Why would I get a tool when I can do that myself?" He thought, "I'm not good if I use these tools."

Abdul did what typical DBAs would do to troubleshoot these issues—look at wait stats, IO metrics, determine which queries are running long, etc., based on scripts he has collected over the years. However, the reality was that the data collection and analysis process to find the issues took him 2 to 3 hours - hours when the business expected the SQL Server data warehouse to be operational to meet their customer needs. Whether the problem was related to parameter sniffing, out-of-date statistics, the need to rebuild indexes, or introducing new code, the organization suffered, increasing the already mounting pressure on the SQL Server DBAs.

From Hours to Minutes

Then, after attending a SQL event and influenced by industry leaders, Abdul had a change in mindset. He was convinced that moving from DIY (Do-It-Yourself) troubleshooting to proactive troubleshooting would reflect his maturity and confidence in his skill set. Abdul said, "Getting Sentry One literally changed my job from 3 hours of troubleshooting to 2 or 3 minutes to pinpoint where the problem occurred." That time savings is critical for DBAs because uptime is an unwritten expectation from the organization.

Abdul explained how he could quickly and easily get SQL Sentry up and running, get the evidence needed to decipher the issue, i.e., "see where the spike happened" in the SQL Sentry visual interface, and begin resolving the issue to meet the daily 8:00 AM deadline. Abdul said, "SQL Sentry literally saved me several hours - several hours that affected the entire business. I have been singing its praises ever since."

It Keeps Getting Better

As a by-product of using SQL Sentry, Abdul remarked, "Over time, batches got better and better. The recommendations were spot on and problems were less and less. This [SQL Sentry] really improved the overall performance." SQL Sentry was a trusted tool for DBAs to share information and help educate the Developers to prevent future performance situations that could impact the organization.

SQL Sentry Features
