适用场景

  • Cloud Insights ( CI )
  • ONTAP 9
  • ONTAP System Manager
  • NetApp ONTAP 数据管理软件数据收集器(启用了高级指标)

问题描述

  • 无法获取性能数据,因为性能轮询失败,并在 CI OnCommand System Manager 中的数据收集器登录页面中显示以下消息:

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

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.

  • 在查看 storageperformance 相关 ONTAP 集群的数据收集器的示例日志(位于 acq folder >> storageperformance_datacollectornameone of the timestamp folders 中的错误报告 log_sample.log中)后,可能会出现以下错误消息:

示例:

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)

  • 此外,如果尝试在 statistics lif show命令行界面中对集群 SVM 运行命令(通过集群中任一节点的节点管理 LIF 进行访问),则也可能会出现类似的错误,如下所示。 

注意: 此错误消息应与从 CI 中的性能示例日志中获取的突出显示部分相同,但这 performance-object  两个错误消息之间的特定 ZAPI 调用可能不同:

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.
