The Log Switch Frequency Map shows the incorrect number of logs cut on an Oracle RAC server. Log switch frequency map has a drop down for the instances and "ALL".
When viewing a single instance the chart shows the correct total number of logs created for ALL the instances, not just the one selected in the drop down list.
Selecting other instances doesn't change the map at all, still showing the total created across ALL instances. Selecting ALL, multiplies the number that was shown for one instance by the number of instances in the RAC server.
Waiting for fix in a future release of Toad for Oracle.
