Performance Monitor ( v16 and following releases)

重要: If you have upgraded from a previous version to v16, the Performance Monitor data rollup will continue to use the previous version default rollup settings (see Performance Monitor (Prior to v16) section below). If you have installed a clean install of v16, then the Performance Monitor data rollup default settings are as follows:
  • Rollup raw data after. Raw data is data that is gathered during each reporting interval configured through Device Properties - Performance Monitors. Until raw data is rolled up, it takes up one row per poll in the database, and cannot be deleted from the database. When raw data is rolled up, it is consolidated into one row per hour. It is recommended to set this value as low as possible (as low as 1 hour), to avoid database overgrowth. Select the number of days and/or hours in the time boxes. By default, rolls up raw data after 12 hours. This means that between the 12th and 13th hour, rolls up raw data into hourly data.
  • Rollup hourly data after. After hourly data is rolled up to daily data, hourly entries are flagged as "deleted," and are overwritten with new performance monitor data. The number in the hourly data box must be greater than the number of raw data days. By default, rolls up hourly data after 3 days. This means that between the 24th hour on the 3rd day and the 1st hour on the 4th day, rolls up hourly data into daily data.
  • Expire daily data after. After daily data is expired, it is flagged as "deleted" and is overwritten with new performance monitor data. The number in the daily box must be greater than the number of hourly data days. By default, expires daily data after 90 days. This means that in between the 24th hour on the 90th day and the 1st hour on the 91st day, expires daily data.
    注: After a database entry is flagged as "deleted," although it still exists in the database, it is no longer included in report data. As new performance monitor data is gathered, database entries flagged as "deleted" are overwritten with new data.
