PG_TOTAL_USER_RESOURCE_INFO displays the resource usage of all users. Only administrators can query this view. This view is valid only if use_workload_manager is set to on.

Table 1 PG_TOTAL_USER_RESOURCE_INFO columns

Name

Type

Description

username

name

Username

used_memory

integer

Memory used by a user, in MB.

  • On a DN, it indicates the memory used by users on the current DN.
  • On a CN, it indicates the total memory used by users on all DNs.

total_memory

integer

Memory used by the resource pool, in MB. 0 indicates that the maximum available memory is not limited and depends on the maximum available memory of the database (max_dynamic_memory). The calculation formula is as follows:

total_memory = max_dynamic_memory * parent_percent * user_percent

On a CN, it indicates the total maximum available memory on all DNs.

used_cpu

double precision

Number of CPU cores in use. Only the CPU usage of complex jobs in the non-default resource pool is collected, and the value is the CPU usage of the related cgroup.

total_cpu

integer

Total number of CPU cores of the Cgroup associated with a user on the node

used_space

bigint

Used permanent table storage space (unit: KB)

total_space

bigint

Available storage space (unit: KB). -1 indicates that the storage space is not limited.

used_temp_space

bigint

Used temporary table storage space (unit: KB)

total_temp_space

bigint

Available temporary table storage space (unit: KB). -1 indicates that the storage space is not limited.

used_spill_space

bigint

Size of the used operator flushing space, in KB

total_spill_space

bigint

Size of the available operator flushing space, in KB. The value -1 indicates that the operator flushing space is not limited.

read_kbytes

bigint

On a CN, it indicates the total number of bytes logically read by a user on all DNs in the last 5 seconds, in KB.

On a DN, it indicates the total number of bytes logically read by a user from the instance startup time to the current time, in KB.

write_kbytes

bigint

On a CN, it indicates the total number of bytes logically written by a user on all DNs in the last 5 seconds, in KB.

On a DN, it indicates the total number of bytes logically written by a user from the instance startup time to the current time, in KB.

read_counts

bigint

On a CN, it indicates the total number of logical reads performed by a user on all DNs in the last 5 seconds.

On a DN, it indicates the total number of logical reads performed by a user from the instance startup time to the current time.

write_counts

bigint

On a CN, it indicates the total number of logical writes performed by a user on all DNs in the last 5 seconds.

On a DN, it indicates the total number of logical writes performed by a user from the instance startup time to the current time.

read_speed

double precision

On a CN, it indicates the sum of average logical read rates of a user on all DNs in the last 5 seconds, in KB/s.

On a DN, it indicates the average logical read rate of a user on the DN in the last 5 seconds, in KB/s.

write_speed

double precision

On a CN, it indicates the sum of average logical write rates of a user on all DNs in the last 5 seconds, in KB/s.

On a DN, it indicates the average logical write rate of a user on the DN in the last 5 seconds, in KB/s.

send_speed

double precision

On a CN, it indicates the sum of the average network sending rates of a user on all DNs in the last 5 seconds, in KB/s.

On a DN, it indicates the average network sending rate of a user on the DN in the last 5 seconds, in KB/s.

recv_speed

double precision

On a CN, it indicates the sum of the average network receiving rates of a user on all DNs in the last 5 seconds, in KB/s.

On a DN, it indicates the average network receiving rate of a user on the DN in the last 5 seconds, in KB/s.
