- Install Promonitor
This monitor will check the time interval between log switches and notify if it happens too often.
Oracle's recommendation is that the interval for log switches be 15 to 30 minutes apart, with a maximum of four log switches per hour
Create a new rule and set the thresholds accordingly. You must use multi-threshold syntax with this monitor.
