Column name | Description |
---|---|
last_run |
Time sp_monitor was last run. |
current_run |
Time sp_monitor is being run. |
seconds |
Number of elapsed seconds since sp_monitor was run. |
cpu_busy |
Number of seconds that the server computer's CPU has done [!INCLUDE ssNoVersion] work. |
io_busy |
Number of seconds that [!INCLUDE ssNoVersion] spent doing input and output operations. |
idle |
Number of seconds that [!INCLUDE ssNoVersion] was idle. |
packets_received |
Number of input packets read by [!INCLUDE ssNoVersion]. |
packets_sent |
Number of output packets written by [!INCLUDE ssNoVersion]. |
packet_errors |
Number of errors encountered by [!INCLUDE ssNoVersion] while reading and writing packets. |
total_read |
Number of reads by [!INCLUDE ssNoVersion]. |
total_write |
Number of writes by [!INCLUDE ssNoVersion]. |
total_errors |
Number of errors encountered by [!INCLUDE ssNoVersion] while reading and writing. |
connections |
Number of logins or attempted logins to [!INCLUDE ssNoVersion]. |
[!INCLUDE ssNoVersion] keeps track, through a series of functions, of how much work was done. Executing sp_monitor
displays the current values returned by these functions and shows how much they have changed since the last time the procedure was run.
For each column, the statistic is printed in the form number(number)-number% or number(number). The first number refers to the number of seconds (for cpu_busy
, io_busy
, and idle
) or the total number (for the other variables) since [!INCLUDE ssNoVersion] was restarted. The number in parentheses refers to the number of seconds or total number since the last time sp_monitor
was run. The percentage is the percentage of time since sp_monitor
was last run. For example, if the report shows cpu_busy
as 4250(215)-68%
, the CPU was busy 4,250 seconds since [!INCLUDE ssNoVersion] was last started up, 215 seconds since sp_monitor
was last run, and 68 percent of the total time since sp_monitor
was last run.
Requires membership in the sysadmin fixed server role, or execute permission directly on this stored procedure.
The following example reports information about how busy [!INCLUDE ssNoVersion] has been.
USE master;
GO
EXEC sp_monitor;
