System: NSCD Operations

This statistic shows requests made to NSCD (Name Service Cache Daemon).

An understanding of operating system internals may be required to properly interpret this statistic.

When to Check NSCD Operations

This can be used to check the effectiveness of the NSCD cache, by using the hit/miss breakdown. Misses become backend requests to remote sources, which can be examined using System NSCD backend requests.
