Columns
Column |
Type |
Nullable? |
Description |
|---|---|---|---|
| SVR_IP | varchar(46) | NO | The IP address of the server. |
| SVR_PORT | bigint(20) | NO | The port of the server. |
| ZONE | varchar(128) | NO | The name of the zone. |
| SQL_PORT | bigint(20) | NO | The SQL port. |
| CPU_CAPACITY | bigint(20) | NO | The total CPU capacity of the node. |
| CPU_CAPACITY_MAX | double | NO | The overcommitted CPU capacity of the node. It is controlled by the resource_hard_limit parameter: CPU_CAPACITY_MAX = CPU_CAPACITY * resource_hard_limit. |
| CPU_ASSIGNED | double | NO | The number of CPUs allocated to the OBServer node. It is the sum of the MIN_CPU specifications of all units on the OBServer node. The following constraint applies: CPU_ASSIGNED <= CPU_CAPACITY. |
| CPU_ASSIGNED_MAX | double | NO | The upper bound of the number of CPUs allocated to the OBServer node. It is the sum of the MAX_CPU specifications of all units on the OBServer node. The following constraint applies: CPU_ASSIGNED_MAX <= CPU_CAPACITY_MAX. |
| MEM_CAPACITY | bigint(20) | NO | The total memory size available for tenant allocation on the OBServer node, which is calculated as memory_limit - system_memory, in bytes. |
| MEM_ASSIGNED | bigint(20) | NO | The memory size allocated to the OBServer node, which is the sum of the MEMORY_SIZE specifications of all units on the OBServer node, in bytes. The following constraint applies: MEM_ASSIGNED <= MEM_CAPACITY. |
| LOG_DISK_CAPACITY | bigint(20) | NO | The total size of the log disk space, in bytes. |
| LOG_DISK_ASSIGNED | bigint(20) | NO | The size of the log disk space allocated to the OBServer node, which is the sum of the LOG_DISK_SIZE specifications of all units on the OBServer node, in bytes. |
| LOG_DISK_IN_USE | bigint(20) | NO | The size of the log disk space used by the OBServer node, in bytes. |
| DATA_DISK_CAPACITY | bigint(20) | NO | The total size of the data disk space on the OBServer node, in bytes. |
| DATA_DISK_ASSIGNED | bigint(20) | YES | This field is set to NULL, indicating that the disk space is not defined and can be used by other tenants.
NoteThis field was introduced in V4.3.3. |
| DATA_DISK_IN_USE | bigint(20) | NO | The data disk size used by the OBServer node, in bytes. |
| DATA_DISK_HEALTH_STATUS | varchar(20) | NO | The health status of the data disk. NORMAL: normalWARNING: abnormalERROR: error |
| MEMORY_LIMIT | bigint(20) | NO | The total memory size available to the OBServer node, in bytes. |
| DATA_DISK_ALLOCATED | bigint(20) | NO | The size of the data disk allocated to the OBServer node, in bytes
NoteThis field was introduced in V4.2.0. |
| DATA_DISK_ABNORMAL_TIME | timestamp(6) | NO | The last time when the data disk was in the WARNING or ERROR state. |
| SSL_CERT_EXPIRED_TIME | timestamp(6) | NO | The expiration time of the SSL certificate in use on the OBServer node when SSL is enabled, in microseconds. |
| SS_DATA_DISK_OPERATION_SUGGESTED | varchar(32) | YES | This field is set to NULL.
Note
|
| SS_DATA_DISK_SIZE_SUGGESTED | bigint(20) | YES | This field is set to NULL.
