What is the log retention period?
---------------------------------
The monitor uses 2 different tables in the database to store history information regarding servers.
The first one is called the "uptime" table. This one keeps full track of the past 7 days, so that detailed information is available (e.g. which checks failed/passed etc).
This allows the monitor to create a detailed graph on the server info page.
In order to prevent the uptime table growing beyond reasonable, after a week the uptime records are archived to a different table.
Archiving means that per day only one record is stored with averages. This still allows some basic statistics, although they are not as detailed as the uptime records.
The retention period tells the monitor how long to keep records in the archive table.
