Processes and databases
Published 28 March 2024
Blocking Processes
Information from the blocked process report. For each blocking process, you’ll see the full blocking chain, along with the details of which application issued the process, resources involved (tables, indexes, etc.), the SQL text being executed, and more. Blocking processes can raise the blocking process alert (see List of alerts for details).
For more information on troubleshooting blocking, see: Blocking Processes Overview.
SQL User Processes
Information is collected from the sys.dm_exec_requests, sys.dm_exec_sessions, and sys.dm_exec_connections views.
For each SQL user process, you'll see information including the last command requested, timestamps, and the program that issued the command.
Processes (Server)
Name of each server process, including WMI processes, how long it’s been running, and sparklines of its processor and memory use, over the period.
Availability Groups
There is also a list of availability groups (AGs) showing the status of each one. Click on an AG to go to its Overview page, revealing useful information on the status of the primary and available replicas and metrics such as log growth, the size for the send and redo queues, length of transaction delays and more.
See: Availability group overview for more details.
Error log
A list of any recorded errors from the SQL Server error log.
Databases
A searchable list of databases, with database-level attributes (name and availability) and a sparkline of transactions per second and database size for each one. If you click on a database, you'll see a whole range of database-level metrics, properties and details of recent backups.
Counters
SqlServer:Database-Performance (transactions, log activity).
Transactions/sec
Number of transactions started for the database per second. Each data point shows the average number of transactions per second since the previous data point.
Active transactions
Number of active transactions for the database. Each data point shows the number of active transactions at the point the data was collected.
Log bytes flushed/sec
Average size of the log flush per second. Each data point shows the average log bytes flushed per second for this database since the previous data point.
Log flushes/sec
Number of log flushes per second for this database, averaged since last collection time.
Log flush waits/sec
Number of transaction commits per second waiting to be flushed from the log cache to the physical transaction log file on disk.
SqlServer:Database-Storage (total file sizes and space usage for data and log files).
Total data file size
Total size of all data files (.mdf and .ndf files) for the specified database.
Total log file size
Total size of all log files (.ldf) for this database.
Total log space used
Total transaction log file size currently containing log records.
