What parameter would you change if you want to modify the pruning of old Puppet data from default 30 days?

The parameter that controls the pruning of old Puppet data is "prune_until." This parameter is specifically designed to set the limit on how long old data will be retained before it is pruned or removed. By default, Puppet retains data for 30 days, but adjusting the "prune_until" parameter allows you to extend or shorten this timeframe as per your requirements.

Using this parameter effectively can help in managing the amount of historical data stored within Puppet, thereby improving performance and ensuring that the data remains relevant. The ability to customize this setting provides flexibility in data retention policies, which can be crucial depending on the operational needs of the environment.

The other options do not directly correlate with the time-based pruning of old data. They refer to different functionalities within Puppet or have incorrect naming conventions related to data pruning. Thus, "prune_until" is the correct term to modify retention settings for old Puppet data effectively.
