Counters belong to two categories
|
|
1. Active Counter - one that counts up and down
|
|
It is expected that this counter consists of the current
|
|
active items and hence this should not be wildly high, unless
|
|
there are large # of counted objects.
|
|
|
|
2. Cumulative Counters - counts values up and up
|
|
This count value is used to measure the # of times event(s)
|
|
related to this counter occurred.
|
|
|
|
Naming Conventions:
|
|
prefixes used are: Aac & Cac
|
|
Aac - Active Auxiliary Counter
|
|
Cac - Cumulative Auxiliary Counter
|
|
Ac - Auxiliar Counter
