Spotting Unauthorized Configuration Settings in SQL Server
If someone makes unauthorized changes to SQL Server configuration settings, it could compromise the availability, performance or security of your servers. Using using Extended Events, and a custom metric, in SQL Monitor, Phil Factor offers a way to get an immediate notification of such changes, and investigate their cause. Read moreHow to Detect SQL Injection Attacks using Extended Events and SQL Monitor
Phil Factor shows how to monitor for the errors indicative of a possible SQL Injection attack on one of your SQL Server databases, using a SQL Monitor custom metric that uses diagnostic data from Extended Events. Read moreThe Changing Role of SQL Server Monitoring
Grant Fritchey explains how a modern monitoring tool must adapt, as our SQL Server databases grow in number and size, and migrate onto new cloud-based, containerized or virtual machine-based SQL Servers. Read moreTroubleshooting Blocking in SQL Server using SQL Monitor
SQL Monitor tells us immediately when significant blocking occurs, and where, during busy periods, and provides the full blocking chain, in an easy-to-digest graphical format, so we can diagnose and resolve the blocking quickly. Read moreMonitoring Distributed SQL Servers using SQL Monitor
If your SQL Server estate is large, or installed across different, isolated networks, or both, then you need a distributed monitoring solution. It is very easy to set up multiple base monitors in SQL Monitor, and then to manage the monitoring, alerting and troubleshooting for your entire SQL Server estate, from a single web interface. Read moreCustom Metrics for Detecting Problems with Ad-hoc Queries
Overuse of ad-hoc queries by applications is a common source of SQL Server performance problems. The symptoms include high CPU and memory pressure. Phil Factor offers a simple custom metric to monitor the percentage of ad-hoc queries being executed on a database, and shows how SQL Monitor can detect when the problem is happening, and show you the queries that are affecting the server. Read moreUsing SQL Monitor to Detect Problems on Databases that use Snapshot-based Transaction Isolation
Use of the read committed snapshot isolation level is often an effective way to alleviate blocking problems in SQL Server, without needing to rewrite the application. However, it can sometimes lead to tempdb contention. This article offers a small-scale solution (not suitable for use on large tables) to detect cases when tempdb contention is related to use of RCSI. Read moreMonitoring and Troubleshooting Deadlocks with Redgate Monitor
This article explains what SQL Server deadlocks are, why they occur, why they require immediate investigation, and the diagnostic data required to troubleshoot them. It then demonstrates an "Update Order" deadlock condition and shows how to find the cause quickly, in Redgate Monitor, using the Extended Events deadlock graph provided by the deadlock alert.
