A.1 Data Expiration Policy
This section lists the order in which Sentinel Log Manager chooses to delete data from the archive or
from the local storage locations. Sentinel Log Manager deletes the data types in their listed order
until the required space is available.
Data is deleted in the following order:
1. All partitions (both online and archive) are deleted as soon as the keep at most time limit of
their retention policy completes.
2. Partitions that are successfully archived (oldest first until none-left or the desired amount of
space is available).
3. Partitions that are not yet archived, but completed their retention policy's keep at most time
limit (ordered by the largest amount of time completed the keep at most limit, until none left or
the desired amount of space is available).
If at least half of the desired space is not yet been freed, then partitions are deleted prematurely,
considering that the incoming data is more important than any old data.
4. Partitions that are not archived and completed their policy's keep at most time limit (ordered by
the shortest amount of time before the keep at most limit, until none left or at least half of the
desired amount of space is available, but the current UTC day partitions are not deleted).
A.2 Database Users
The installer creates and configures a PostgreSQL database with users.
There are several users created by default:
dbauser: The database owner (database administrator user). The password is set during the
installation process.
appuser: A user that is used by the Sentinel Log Manager server process (the ConnectionManager)
to log in to the database. The password is randomly generated during the installation process, and it
is intended for internal use only.
admin: The administrator credentials can be used to log in to the Sentinel Log Manager Web
interface. The password is set during the installation process.
