tenantName string Name of the tenant.
totalQueries number Total number of queries submitted to Impala.
successfulQueries number Number of queries that finished successfully.
oomQueries number Number of queries that failed due to insufficient memory.
timeOutQueries number Number of queries that timed out while waiting for resources in a pool.
rejectedQueries number Number of queries that were rejected by Impala because the pool was full.
avgWaitTimeInQueue number Average time, in milliseconds, spent by a query in an Impala pool while waiting for resources.
peakAllocationTimestampMS number The time when Impala reserved the maximum amount of memory for queries.
maxAllocatedMemory number The maximum memory (in bytes) that was reserved by Impala for executing queries.
maxAllocatedMemoryPercentage number The maximum percentage of memory that was reserved by Impala for executing queries.
utilizedAtMaxAllocated number The amount of memory (in bytes) used by Impala for running queries at the time when maximum memory was reserved.
utilizedAtMaxAllocatedPercentage number The percentage of memory used by Impala for running queries at the time when maximum memory was reserved.
peakUsageTimestampMS number The time when Impala used the maximum amount of memory for queries.
