In the previous part of the SQL Server performance metrics series, we presented the most important and useful disk performance metrics. Now, we’ll show other important disk performance measures Read more »

So far, we have presented the most important memory and processor metrics. These metrics indicate system and SQL Server performance, and are useful for troubleshooting performance issues and bottlenecks. Besides memory and processor metrics, equally important are SQL Server disk metrics. Sometimes a metric from one category can be masked by other events and be misleading – e.g. a disk issue can cause processor bottlenecks. That’s why it’s necessary to understand the cause and effect of each metric Read more »

In the previous part of this series, we presented the processor metrics that indicate hardware component problems that can affect SQL Server performance

In this part, we will present processor metrics that are not necessary in every performance monitoring scenario, but are useful for deeper investigation and troubleshooting Read more »

In the Part 1 and Part 2 of the SQL Server processor performance metrics series, we described the most important processor performance metrics – Processor: % Processor Time, Process: % Processor Time, Processor Queue Length, Processor: % User Time, Processor: %Privilege Time, as well as various total times and thread metrics Read more »

In SQL server processor performance metrics – Part 1 – The most important cpu metrics, we described the Processor Queue Length and two most important processor time counters – Processor % Processor Time and Process % Processor time

In this part, we will continue describing important time processor counters Read more »

In the previous parts of the SQL Server performance metrics series, we described and recommended various memory metrics that should be tracked when monitoring SQL Server performance. Besides the memory metrics, monitoring processor usage and disk performance is recommended Read more »

So far, we have described the most popular and most important SQL Server memory metrics. Monitoring these metrics is recommended in every scenario when SQL Server performance monitoring and troubleshooting is needed. Besides the SQL Server Memory Manager metrics, the memory pressure can be indicated via the Buffer Manager metrics, as the buffer is the component that uses most of the SQL Server memory Read more »

We’ve started the SQL Server performance metrics series with the SQL Server memory metrics that should be monitored to indicate and help troubleshoot SQL Server performance issues

In this part, we will continue with SQL Server memory performance metrics and present Lazy Writes, Free List Stalls/sec, and Memory Grants Pending Read more »

In the previous parts of the SQL Server performance metrics series, we presented most important SQL Server memory metrics that indicate overall SQL Server memory pressure. The described metrics show how SQL Server uses memory and physical I/O to store, read and write data pages. In this part, we continue with SQL Server Buffer Manager metrics and memory counters Read more »

In the first part of this series, we started with most important SQL Server performance memory metrics. We described Pages/sec and Page faults/sec, what they indicated, and what the normal values were In this part, we will present three more memory metrics that affect SQL Server performance – Available memory bytes, Total server memory, and Target server memory Read more »

In the SQL Server performance basics article, we explained why performance monitoring was important and what you should consider before you start monitoring SQL Server performance Read more »
