SQL Server Deadlock Monitoring Tool

Quickly diagnose and resolve SQL Server deadlocks

Save time troubleshooting SQL Server deadlocks

SolarWinds® SQL Sentry displays deadlocks in SQL Server and shows you the total time lost during those deadlocks. You can find a metric called Victim Impact information in the deadlock summary report. With SQL Server Deadlock tool, you can:

  • View statements that executed while the deadlock occurred
  • Avoid installing agents or set trace flags to gather the relevant information about deadlocks
  • Eliminate the need to translate SPIDs or reference IDs—the host, application, and resource names are labeled in the deadlock graph

Identify victims and survivors of deadlocks in SQL Server

The first step in analyzing the impact of deadlocks on applications is to identify the “victims” (either a rolled back transaction or a failed process) and the “survivors.” SQL Server often chooses the least expensive transaction to roll back as the deadlock victim.

SQL Sentry resolves deadlock contention by identifying a victim based on process ID and supplying information about deadlock wait time, which helps ensure an effective resolution while offering you the deadlock monitoring insights you need.

Quickly visualize SQL Server deadlocks in the Management Studio

SQL Sentry can export captured deadlock information in an open file format. The files can be viewed and shared as needed. You can even view the files inside the SQL Server Management Studio (SSMS) for ultimate accessibility.

Share SQL Server deadlock information to help resolve issues

Depending on the type of deadlock, a database admin may need to share deadlock information with developers to come up with an optimal resolution.

SQL Sentry gives DBAs the ability to share information with the team via email and provides recommendations on ways to resolve the deadlock. For example, suppose a DBA finds an application in SQL Sentry and sees several queries in the same application are deadlocking the same objects. In that case, they can easily email the SQL Sentry deadlock report to their team and suggest the developers review SQL Sentry’s strategies for resolving deadlocks.

Use deadlock playback for faster analysis

The deadlock playback capability helps you analyze the source of deadlocks by displaying the events that led to the deadlock. This functionality can help you reverse-engineer a deadlock.

With the playback, you can watch the diagram cycle through the events, which is like watching the deadlock happen again in real time. Playback controls include the ability to skip forward, fast forward, rewind, change the playback speed, and zoom in or out on the deadlock graph.
