Here's what it does, and how it works. Read moreTracking SQL Server Configuration Across All Your Servers Using SQL Monitor
The Estate Configuration reports SQL Server configuration across all your servers, so you can quickly investigate ad-hoc or unauthorized changes to any settings that might affect their performance, stability, or security. Read moreWhy is my SQL Server Query Suddenly Slow?
A SQL Server query is suddenly running slowly, for no obvious reason. Grant Fritchey shares a 5-point plan to help you track down the cause and fix the problem. Read moreIs Tempdb Causing a Bottleneck?
One of your SQL Server instance shows a major dip in performance or throughput, affecting all the user databases. You notice that the slow interludes coincide, as if orchestrated. On investigation, it appears that several transactions running over that period were using a lot of space in tempdb. However, which of them, if any, are causing the tempdb bottleneck, and why? Read moreTen Reasons your SQL Server Monitoring will Scale
This article explains ten ways that SQL Monitor tackles the problem of scaling out the coverage of a single, lightweight monitoring system, and so allows your teams to maintain the health and performance of larger collections of databases and higher numbers of monitored SQL servers. Read moreImproving SQL Monitor’s Database Performance
Jeremiah Peschka, a tech lead for SQL Monitor development, explains the new SQL Server configuration options available for the data repository, and how enabling them might improve SQL Monitor performance, when reading and writing monitoring data. Read moreWhen SQL Server Performance Goes Bad: Rogue Indexes
Phil Factor explains how SQL Monitor helps focus performance tuning efforts on the tables and queries where 'rogue indexes' might be a significant problem, and then how to identify both 'missing' indexes that might be beneficial to the overall workload, and those that are unused or duplicated, and so are doing more harm than good. Read moreWhen SQL Server Performance Goes Bad: Implicit Conversions
In this article, you'll learn how to detect and remove a common cause of SQL Server query performance problems: reliance on implicit datatype conversions. We'll use a combination of plan cache queries, extended events, and SQL Monitor. Read moreIntroduction to Analyzing Waits using SQL Monitor
Phil Factor sets out with the modest aim of giving you enough of an introduction to waits to better understand the wait information you get from a SQL Server monitoring tool like SQL Monitor, and the rather overwhelming amount of information available in the underlying DMVs and Extended Events. Read moreAutomate Responses to Bad Deployments with SQL Monitor
Jamie Wallis explains how SQL Monitor can both reveal quickly who ran a deployment, and when, and automate the incident-response workflow to ensure it's dealt with swiftly. By extending such workflows to development and test servers, as well as production, the feedback cycle starts earlier, and you can stop problems from ever reaching the users. Read moreWhen SQL Server Performance goes Bad: the Fill Factor and Excessive Fragmentation
Phil Factor on the fill factor, pages splits and index fragmentation, and how SQL Monitor can help you decide if a custom fill factor for certain indexes might help alleviate performance issues. Read moreSQL Monitor Roadtrip: Preparation
Setting up SQL Monitor without a bit of preparation work is a bit like embarking on a road trip without first learning to drive. Phil Factor show the essential kit and route maps you need for the journey. Read moreAdding Reports Users to SQL Monitor
SQL Monitor 10.0.5 now supports a user role called "Reports user". A user added to this role, by an administrator, will be able to 'self-serve' SQL Monitor reports but won't be able to configure any other aspect of the monitoring service. Jeremiah Peschka explains how it works. Read moreWhat’s New in SQL Monitor 10?
SQL Monitor 10 packs a lot more under the hood in terms of connectivity, establishing cause-and-effect, and alerting. This article provides the high-level tour of the features we've introduced or improved, and why. Read moreTagging SQL Server Changes in SQL Monitor
How to use RAISERROR() in T-SQL to send annotations to SQL Monitor, so you can observe the direct impact of application tasks, or server changes, on the SQL Server metrics. Read moreMonitoring TempDB Contention using Extended Events and SQL Monitor
When the tempdb database is heavily used, processes in any database on the instance will be forced to wait, due to contention as the SQL Server engine tries to manage allocation pages in tempdb. Phil Factor shows how to monitor for signs of trouble. Read moreTracking the number of active sessions on a database using SQL Monitor
Phil Factor creates a simple custom metric to track the number of sessions that have recently done a read or write on a database. Having established a baseline for the metric, you'll be able to spot, and investigate the cause of, any wild deviations from normal behavior. Read moreMonitoring SQL Server Performance: What’s Required?
A monitoring tool must provide us with an understanding of the often-complex performance patterns that databases exhibit when under load, so that we can predict how they will cope with expansion or increase in scale. It must also helps us spot the symptoms of stress and act before they become problems that affect the service, and understand better what was happening within a database when an intermittent problem started. Read moreMonitoring the Application with SQL Monitor: Website Activity
Using a PowerShell script that collects log data from a web server, plus a SQL Monitor custom metric, Phil Factor offers a way to check for suspicious website errors and unusual patterns of activity, right alongside your database monitoring. Read moreManaging the SQL Server Estate
Rodney Landrum describes how a monitoring tool must help us monitor, analyze and predict resource usage, including costs, across a growing and diversifying estate, and also help the organization to connect server resource usage and error conditions directly to their impact on business processes. 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 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 SQL 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 SQL Monitor, using the Extended Events deadlock graph provided by the deadlock alert. Read moreInvestigating problems with ad-hoc queries using SQL Monitor
Phil Factor demonstrates the performance problems that overuse of ad-hoc queries can cause and then how SQL Monitor can warn us when they are the cause of these problems on your SQL Servers, using built-in metrics such as SQL Compilations/sec metric and Batch Requests/sec.
