# Cleaning data

# Cleaning collected Performance Analytics data {#ariaid-title1}

Performance Analytics scores and snapshots may grow over time and should be routinely
cleaned to ensure optimal performance and accurate data.

Performance Analytics uses a scheduled job to remove old scores and snapshots.  
The Clean PA collections scheduled job is active by default and has no impact on performance. By default, the job runs daily so it only has to delete a small amount of data.  
Hinweis:  
The dictionary attributes nibble_size and nibble_sleep affect the behavior of the collection cleaner job if the attributes are defined for one of the Score (pa_scores, pa_scores_l1, pa_scores_l2) tables or the Snapshot (pa_snapshots) table. For more information, see [Altering tables and fields using dictionary attributes](https://www.servicenow.com/docs/access?context=c_DictionaryAttributes&version=australia&pubname=australia-platform-administration&ft:locale=en-US).

## Modify the Clean PA collections job {#ariaid-title2}

Modify the scheduled job to configure when Performance Analytics scores and snapshots
are cleaned. The scheduled cleanup job should not run while a data collection job is
running.

### Vorbereitungen

Role required: pa_admin or admin

### Warum und wann dieser Vorgang ausgeführt wird

By default, the Clean PA collections job runs at 05:00 which is appropriate when
using the default data collection jobs. If you create additional data collection jobs,
you may need to change the start time of the Clean PA collections job.

### Prozedur

1. Navigate to AllPerformance AnalyticsAutomationSchedules.
2. Select the Clean PA collections job.
3. Make any necessary changes.  
   For example, change the Run time field value to change when the job runs.
4. Click Update.
