I have a question about the granularity of historic data in Cloudera Manager in the chart builder.
In documentation I found, that service and host monitor manage internally the amount of their overall storage space for every granularity level. When the limit for a particular level is reached, the oldest data points at that level are deleted. It deletes the oldest data of the lowest granularity level.
When does Cloudera Manager know when it should delete old data?
Where can I configure the retention and granularity of the Cloudera chart builder?
