This tool can be used as a Nagios monitoring plugin.
It checks if mysql AUTOINCREMENT columns are getting close to overflow.
By default it produces a WARNING if any autoincrement value reaches
70% of the maximal value that can be stored in the column, and a
CRITICAL if it reaches more than 85% of the maximal value.
Please run
perldoc -F check.autoincrement
to read the tool's documentation, including the options.
