Displaying NIS statistics

You can display NIS statistics for storage virtual machines (SVMs) on the storage system to monitor performance and diagnose issues.

  1. Set the privilege level to advanced: set -privilege advanced.
  2. Use the statistics catalog object show command to identify the NIS objects from which you can view data.

    Example

    statistics catalog object show -object external_service_op*

    For more information about the statistics commands, see the Performance Monitoring Power Guide.
  3. Use the statistics start and statistics stop commands to collect a data sample from one or more objects.
  4. Use the statistics show command to view the sample data.

Monitoring NIS statistics​

The following examples display performance data for NIS queries. The following commands start data collection for a new sample:

vs1::*> statistics start -object external_service_op -sample-id nis_sample1
vs1::*> statistics start -object external_service_op_error -sample-id nis_sample2

The following command displays data from the sample by specifying counters that show the number of NIS queries sent versus the number of NIS queries received, failed, or timed out:

vs1::*> statistics show -sample-id nis_sample1 -counter instance|num_requests_sent|num_responses_received|num_successful_responses|num_timeouts|num_request_failures|num_not_found_responses

The following command displays data from the sample by specifying counters that show the number of times a specific error was received for a NIS query on the particular server:

vs1::*> statistics show -sample-id nis_sample2 -counter server_ip_address|error_string|count
