You can define database retention periods (that is how long databases should keep data) in the PerformanceGuard web interface:

You can only do this if you're a PerformanceGuard administrator.

Backend Database

Select ADMINISTRATION > Setup > Parameters ad then select the Status tab.

Alternatively, you can define backend database retention parameters directly in the database if you edit the Value column of the Status table. SQL example:

use pguard

update pguard.status set value='600' where parameter='KEEP_PERIOD_AGGREGATE_DATA'

The backend server schedules and executes data deletion jobs according to these values. Any parameter value changes will take effect immediately. The following is a non-exhaustive list of parameters:

KEEP_PERIOD_AGENTS

Data from PerformanceGuard agents that haven't been online during this period will be deleted from the database.

Unit: Hours

Default value: 336 (336 hours = 14 days = two weeks)

This parameter won't have any effect if you set it lower than the lowest value of the parameters KEEP_PERIOD_AGGREGATE_DATA, KEEP_PERIOD_TRANSACTION_DATA or KEEP_PERIOD_CITRIX_AGGREGATE_DATA.

KEEP_PERIOD_TREND_DATA

All performance data aggregated at trend level (hours) will be deleted after this period.

Unit: Days

Default value: 470 (470 days = 15,4418 months = 1.25 years)

KEEP_PERIOD_TRANSACTION_DATA

Performance data related to transaction filters aggregated at agent group level will be deleted after this period.

Unit: Hours

Default value: 1488 (1488 hours = 62 days = two 31-day months)

KEEP_PERIOD_CITRIX_AGGREGATE_DATA

Citrix session performance data will be deleted after this period.

Unit: Hours

Default value: 1488 (1488 hours = 62 days = two 31-day months)

KEEP_PERIOD_BTM2_DATA

Business Transaction Monitoring performance data aggregated at agent group level will be deleted after this period.

Unit: Hours

Default value: 1488 (1488 hours = 62 days = two 31-day months)

KEEP_PERIOD_BTM2_DETAIL_DATA

Business Transaction Monitoring performance data at agent level will be deleted after this period.

Unit: Minutes

Default value: 10080 (10080 minutes = 168 hours = seven days = one week)

KEEP_PERIOD_AGGREGATE_DATA

Other performance data aggregated at agent group level will be deleted after this period.

Unit: Hours

Default value: 1488 (1488 hours = 62 days = two 31-day months)

KEEP_PERIOD_DETAIL_DATA

Agent resource data will be deleted after this period.

KEEP_PERIOD_PROCESS_DATA

Agent process data will be deleted after this period.

Unit: Minutes

Default value: 10080 (10080 minutes = 168 hours = seven days = one week)

KEEP_PERIOD_TRAFFIC_DETAIL_DATA

Unit: Hours

Default value: 48 (48 hours = two days)

Frontend Databases

Data retention periods (also known askeep periods) on frontend databases are also controlled by the agent configuration settings (ADMINISTRATION > Agent Configuration > Configurations > [Edit] > Advanced).

See also Agent Configuration Group Settings > Advanced.
