Chronograf, a time series database management tool, allows users to manage alert history by storing data in the `chronograf` database and `alerts` measurement in InfluxDB. By default, this data is subject to an infinite retention policy but can be expired by shortening the duration of that policy through the Admin page in Chronograf. The recommended minimum duration for expiring alert history data is one hour. Additionally, starting with version 1.3.2.0, Chronograf's Data Explorer supports writing data to InfluxDB databases, allowing users to write data directly within the tool instead of using the deprecated web admin interface.
