When Summary Mode is active for the ResUsageSvdsk table, one row is written to the database for each node in the system. This row summarizes all AMP vdisk data in each node per log interval.
You can determine if a row is in Summary Mode by checking the SummaryFlag column for that row.
| IF the SummaryFlag column value is… | THEN the data for that row is being logged… |

| 'N' | normally. |
