Description |
|---|---|---|---|
| TENANT_ID | bigint(20) | NO | Tenant ID |
| SVR_IP | varchar(46) | NO | Node IP |
| SVR_PORT | bigint(20) | NO | Node port |
| STAT_ID | bigint(20) | NO | Stat ID |
| STAT_NAME | varchar(64) | NO | Stat name |
| VALUE | bigint(20) | NO | Stat value |
The following table describes the values in the STAT_NAME column. | Stat name | Description | Stat ID | Stat type | | ------------|------|------------|----------------| | DB time | Total time of database activities, which is the sum of CPU time and non-idle wait time. | 200001 | 3072 | | DB CPU | CPU time of database activities. | 200002 | 3072 | | background elapsed time | Total time of background process execution. | 200005 | 3072 | | background cpu time | CPU time of background processes. | 200006 | 3072 | | non idle wait time | Total time of non-idle waits, which is the total time that a session is in a wait state but not in an idle wait state. | 200010 | 3072 | | idle wait time | Total time of idle waits, which is the total time that a session is in an idle wait state. | 200011 | 3072 | | background database time | Total time of database operations executed by background processes. | 200012 | 3072 | | background database non-idle wait time | Total time of database operations executed by background processes in non-idle wait states. | 200013 | 3072 | | background database idle wait time | Total time of database operations executed by background processes in idle wait states. | 200014 | 3072 | | concurrency wait total time | Total wait time due to concurrency issues, such as wait time due to resource locking. | 220001 | 3072 | | user io wait total time | Total wait time of user processes waiting for I/O operations (such as data reads and writes to the disk) to complete. | 220002 | 3072 |
| application wait total time | Total wait time generated by user application code (such as lock waits caused by row-level locks or explicit lock commands).| 2200013 | 3072 |
