memory-poller-report-threshold.md
The memory poller compares MemoryPollerReportThreshold
with the following expression:
RSS / available-memory
When this expression evaluates to a value higher than MemoryPollerReportThreshold
—by default, set to 0.93, then the memory poller writes a report to MemoryReport.log
, in the Vertica working directory. This report includes information about Vertica memory pools, how much memory is consumed by individual queries and session, and so on. The memory poller also logs the report as an event in system table
MEMORY_EVENTS
, where it sets EVENT_TYPE
to MEMORY_REPORT
.
