GS_WLM_USER_RESOURCE_HISTORY

GS_WLM_USER_RESOURCE_HISTORY stores information about resources used by users and is valid only on primary database nodes. Each record in this table indicates resource usage of a user at a time point, including the memory, number of CPU cores, storage space, temporary space, operator flushing space, logical I/O traffic, number of logical I/O operations, and logical I/O rate. The memory, CPU, and I/O monitoring items record only resource usage of complex jobs. For I/O monitoring items, this parameter is valid only when enable_logical_io_statistics is set to on. The function of saving user monitoring data is enabled only when enable_user_metric_persistent is set to on. Data in the system catalog GS_WLM_USER_RESOURCE_HISTORY comes from the PG_TOTAL_USER_RESOURCE_INFO view.

Table 1 GS_WLM_USER_RESOURCE_HISTORY

Name Type Description
username text Username
timestamp timestamp with time zone Timestamp
used_memory integer Used memory, in MB
total_memory integer Available memory, in MB. The value 0 indicates that the available memory is not limited and depends on the maximum memory available in the database.
used_cpu real Number of CPU cores in use
total_cpu integer Total number of CPU cores of the Cgroup associated with the user on the node
used_space bigint Used storage space, in KB
total_space bigint Available storage space, in KB. The value -1 indicates that the storage space is not limited.
used_temp_space bigint Used temporary storage space, in KB
total_temp_space bigint Available temporary storage space, in KB. The value -1 indicates that the maximum temporary storage space is not limited.
used_spill_space bigint Used space of operator flushing, in KB
total_spill_space bigint Available storage space for operator flushing, in KB. The value -1 indicates that the maximum operator flushing space is not limited.
read_kbytes bigint Byte traffic of read operations in a monitoring period, in KB
write_kbytes bigint Byte traffic of write operations in a monitoring period, in KB
read_counts bigint Number of read operations in a monitoring period
write_counts bigint Number of write operations in a monitoring period
read_speed real Byte rate of read operations in a monitoring period, in KB/s
write_speed real Byte rate of write operations in a monitoring period, in KB/s
