Find current and Max utilization of processes, sessions,resources..etc

I see that many users are trying to find the current utilization and max utilization of processes, sessions, enqueue_locks, resources…etic.

You will get the resource limit details from v$resoruce_limit

SQL> select resource_name, current_utilization, max_utilization from v$resource_limit;
