環境

  • Cloud Insights ( CI )
  • ONTAP 9
  • ONTAP System Manager
  • NetApp ONTAP データ管理ソフトウェアのデータコレクタ(高度な指標が有効)

問題

  • パフォーマンスのポーリング が失敗し、 CI または OnCommand システムマネージャデータコレクタのランディングページに次のメッセージが表示されるため、パフォーマンスデータを取得できません。

Unable to poll performance ... error = Performance Recent Status
Internal error:
com.onaro.sanscreen.acquisition.framework.datasource.DataSourceErrorException: General Error

または

Data ONTAP API fail: System busy: 7 requests on table "perf_object_get_instances" have been pending for 1678674 seconds. The last completed call took 0 seconds.

  • storageperformance 該当 acq folder storageperformance_datacollectornameone of the timestamp folders log_sample.logする ONTAP クラスタのデータコレクタのサンプルログ( >> のエラーレポートで確認)を確認すると、次のエラーメッセージが表示されることがあります。

例:

2021-03-12 17:19:33,895 ERROR [com.onaro.sanscreen.acquisition.datasource.netapp_ontap.NetAppOntapPerformancePackage] datalake collect and report (Poll Count: 1207, Is Macro Poll: false) : [storageperformance] data-collector-name: 1 apis failed: [storageperformance] data-collector-name: perf-object-get-instances(Object : workload) failed: Trying to perform arithmetic between two counters with different cardinality. Counter "read_io_type" has 1 elements, but the other counter "read_io_type" has 10 elements. (1 times)
 

2021-03-12 17:21:54,206 ERROR [com.onaro.sanscreen.acquisition.datasource.netapp_ontap.builder.ZapiIterBase] Aborting all performance api calls due to: perf-object-instance-list-info-iter(Object : lif) failed: System busy: 7 requests on table "perf_object_instance_list_info" have been pending for 2922550 seconds. The last completed call took 0 seconds.

2022-03-19 01:13:22,377 ERROR [com.onaro.sanscreen.acquisition.datasource.netapp_ontap.NetAppOntapPerformancePackage] datalake collect and report (Poll Count: 10124, Is Macro Poll: false) : [storageperformance] data-collector-name: 15 apis failed: [storageperformance] data-collector-name: perf-object-get-instances(Object : workload) failed: RPC: Remote system error [from mgwd on node "node_name" (VSID: -1) to cm at 127.0.0.1] (1 times)

  • さらに statistics lif show、次に示すように、クラスタ SVM に対して CLI でコマンドを実行(クラスタ内のいずれかのノードのノード管理 LIF を介してアクセス)しようとすると、同様のエラーが発生する場合があります。 

:エラーメッセージは、 CI のパフォーマンスサンプルログから取得した強調表示された部分と同一である必要が performance-object  ありますが、 ZAPI コールは 2 つのエラーメッセージで異なる場合があります。

cluster1::> statistics lif show -vserver cluster1
Error: command failed: System busy: 7 requests on table "perf_object_get_instances" have been pending for 1147109 seconds. The last completed call took 0 seconds.
