“The reserve the database maintains for {1} is insufficient. This data is stored on disk(s) {2}. The database size is {3} MB, the reserve size is: {4} MB ({5}%).

Detector parameters

  • Reserve Threshold [% of Database Size] (number as percentage)
    The threshold value of the remaining free space, expressed as a percentage of the current size of the database.

This number is represented in the alert message as parameter {5}.
