@@ -21,7 +21,7 @@ Note the following behaviors of these data retention settings:
* Data in the `/wal` and `/head_chunks` directories counts toward the retention size limit, but Prometheus never purges data from these directories based on size- or time-based retention policies.
Thus, if you set a retention size limit lower than the maximum size set for the `/wal` and `/head_chunks` directories, you have configured the system not to retain any data blocks in the `/prometheus` data directories.
* The size-based retention policy is applied only when Prometheus cuts a new data block, which occurs every two hours after the WAL contains at least three hours of data.
* If you do not explicitly define values for either `retention` or `retentionSize`, retention time defaults to 15 days, and retention size is not set.
* If you do not explicitly define values for either `retention` or `retentionSize`, retention time defaults to 11 days, and retention size is not set.
* If you define values for both `retention` and `retentionSize`, both values apply.
If any data blocks exceed the defined retention time or the defined size limit, Prometheus purges these data blocks.
* If you define a value for `retentionSize` and do not define `retention`, only the `retentionSize` value applies.
