Description |
---|---|---|---|
EngineNumber |
smallint |
Number of the engine. |
|
CurrentKPID |
smallint |
Kernel process identifier (kpid) for the currently executing process. |
|
PreviousKPID |
int |
kpid for the previously executing process. |
|
CPUTime |
int |
Counter, reset |
Total time, in seconds, the engine has been running. |
SystemCPUTime |
int |
Counter, reset |
Time, in seconds, the engine has been executing system database services. |
UserCPUTime |
int |
Counter, reset |
Time, in seconds, the engine has been executing user commands. |
IdleCPUTime |
int |
Counter, reset |
Time, in seconds, the engine has been in idle spin mode. |
Yields |
int |
Counter, reset |
Number of times this engine yielded to the operating system. modify the rate of yielding during idle periods using runnable process search count. |
Connections |
int |
Counter |
Number of connections this engine handles. |
DiskIOChecks |
int |
Counter, reset |
Number of times the engine checked for asynchronous disk I/O. Modify the frequency of these checks with i/o polling process count. |
DiskIOPolled |
int |
Counter, reset |
Number of times the engine polled for completion of outstanding asynchronous disk I/O. The polling occurs whenever disk I/O checks indicate that asynchronous I/O has been posted and is not yet complete. |
DiskIOCompleted |
int |
Counter, reset |
Number of asynchronous disk I/Os completed when the engine polled for outstanding asynchronous disk I/O. |
MaxOutstandingIOs |
int |
Current number of I/O requests initiated by this engine that are not completed. |
|
ProcessesAffinitied |
int |
Number of processes associated with this engine. |
|
ContextSwitches |
int |
Counter, reset |
Number of context switches. |
HkgcMaxQSize |
int |
Maximum number of items Adaptive Server can queue for housekeeper garbage collection in this engine. |
|
HkgcPendingItems |
int |
Number of items yet to be collected by housekeeper garbage collector on this engine. |
|
HkgcHWMItems |
int |
Maximum number of pending items queued for housekeeper garbage collector at any instant since server started. |
|
HkgcOverflows |
int |
Number of items that could not be queued to housekeeper garbage collector due to queue overflows. |
|
Status |
varchar(20) |
Null |
Status of the engine (online, offline, and so on). |
Starttime |
datetime |
Null |
Date that the engine came online. |
StopTime |
datetime |
Date that the engine went offline. |
|
AffinitiedToCPU |
int |
Null |
