SQL Server channel requirements
Trust Protection Foundation logs events to the location that is defined in the default channel. At installation time, the events log to the Trust Protection Foundation database. However, if there are large volumes of events, you may want to consider creating a separate database and corresponding custom SQL Server channel just for processing log events.
As a general baseline, Trust Protection Foundation generates about 10 events per certificate renewal. Daily events include validation checks and certificate monitoring. The space you need for your database depends on a number of factors. These include, but are not limited to, how many events per second you are storing and how long you want to keep the data.
IMPORTANT You must ensure the database server that stores the channel data does not run out of disk space. If the server runs out of disk space, the log server cannot operate.

WARNING! If you are using your Trust Protection Foundation server as your logging server, if your server runs out of disk space, the entire set of Palo Alto Networks services on that server will stop working.
When using a separate MS SQL database, please refer to the Supported Databases section in the general System Requirements, as the specifications are the same.
