SQL Server, General Statistics Object

The SQLServer:General Statistics object in SQL Server provides counters to monitor general server-wide activity, such as the number of current connections and the number of users connecting and disconnecting per second from computers running an instance of SQL Server. This can be useful when you are working on large online transaction processing (OLTP) type systems where there are many clients connecting and disconnecting from an instance of SQL Server.

This table describes the SQL ServerĀ General Statistics counters.

SQL Server General Statistics counters

Description

Active Temp Tables

Number of temporary tables/table variables in use.

Connection resets/sec

Total number of logins started from the connection pool.

Event Notifications Delayed Drop

Number of event notifications waiting to be dropped by a system thread.

HTTP Authenticated Requests

Number of authenticated HTTP requests started per second.

Logical Connections

Number of logical connections to the system.

The main purpose of logical connections is to service multiple active result sets (MARS) requests. For MARS requests, every time that an application makes a connection to SQL Server, there may be more than one logical connection that corresponds to a physical connection.

When MARS is not used, the ratio between physical and logical connections is 1:1. Therefore, every time that an application makes a connection to SQL Server, logical connections will increase by 1.

Logins/sec

Total number of logins started per second. This does not include pooled connections.

Logouts/sec

Total number of logout operations started per second.

Mars Deadlocks

Number of MARS deadlocks detected.

Non-atomic yield rate

Number of non-atomic yields per second.

Processes blocked

Number of currently blocked processes.

SOAP Empty Requests

Number of empty SOAP requests started per second.

SOAP Method Invocations

Number of SOAP method invocations started per second.

SOAP Session Initiate Requests

Number of SOAP Session initiate requests started per second.

SOAP Session Terminate Requests

Number of SOAP Session terminate requests started per second.

SOAP SQL Requests

Number of SOAP SQL requests started per second.

SOAP WSDL Requests

Temp Tables Creation Rate
