  • API calls return a "null" value
    • When reviewing the recordings from the Nimble array found on the Cloud Insights Acquisition Unit (AU), the following error is found:
      2023-03-02 13:49:38,526 ERROR [com.onaro.sanscreen.acquisition.framework.datasource.BaseDataSource] [storageperformance] Nimble - Runtime exception: null
      java.lang.NullPointerException: null
          at com.onaro.sanscreen.acquisition.datasource.hp_nimble_rest.builder.NimbleVolumeSampleSetBuilder.build(NimbleVolumeSampleSetBuilder.java:60) ~[hp_nimble_rest.jar9778417344889969336.jar:?]
    • Recordings are zip files located in /opt/netapp/cloudinsights/acq/logs on the AU.
      Review the /root/log_sample.log located in the zip for the error message.
    • This can also be validated by running the following API:
      GET https://ip_or_fqdn:5392/v1/volumes/detail
    • We expect EACH volume to have an attribute with an array like:
      avg_stats_last_5mins":{"combined_iops":0,"combined_latency":0,"combined_throughput":0,"read_iops":0,"read_latency":0,"read_throughput":0,"write_iops":0,"write_latency":0,"write_throughput":0}
