[Performance counter] # Gen 1 Collections [Description] 
Displays the number of times the generation 1 objects are garbage collected since the application started. The counter is incremented at the end of a generation 1 garbage collection. Higher generation garbage collections include all lower generation collections. This counter is explicitly incremented when a higher generation (generation 2) garbage collection occurs. This counter displays the last observed value. The _Global_ counter value is not accurate and should be ignored.
