With the slow operation plugin, slow executing operation can be found. This is done by checking on the caller side which operations take a lot of time executing.
This plugin is very cheap to use.
If set to 0, the plugin is disabled.

public long getPeriodMillis()
DiagnosticsPlugin
If a monitor is disabled, 0 is returned.
If a monitor should run only once, a negative value is returned. This is
useful for 'static' monitors like the SystemPropertiesPlugin
that run at the beginning of a log file but their contents will not
change.
