Name Service: Lookups

This statistic shows requests made by the name service to back-end sources, such as LDAP, DNS, and NIS.

An understanding of operating system internals is helpful to interpret this statistic.

When to Check Name Service Lookups

Check the latency breakdown if long latencies are experienced on Oracle ZFS Storage Appliance, especially during administrative logins. The database name breakdown shows what the latency is for, and the source breakdown shows which remote server is responsible. For average latency, see Name Service: Lookups Average Latency.

Name service analytics should be used primarily to analyze performance and diagnose name service problems during investigations. Name service analytics should not be run continuously because they will unnecessarily consume system resources. You could generate an alert if the average latency substantially increases for a period of time, and the alert will appear on the dashboard. To set a threshold alert, see Configuring a Threshold Alert - BUI, CLI.
