Checking the collection of metadata for devices

After you add a device for monitoring, metadata is automatically collected on a regular basis. The type of device determines the metadata that is collected, which can include status, configuration, capacity, and performance metadata.

  • Status, configuration, and capacity metadata are collected by probes and aggregated once every 24 hours.
    • For DS8000 storage systems and their pools, the value for used capacity is collected once every hour. To customize that interval, contact IBM® Support.
    • For some devices, additional probes are automatically run when specific events occur on those devices, or when many events are detected in a short time period. To avoid performance bottlenecks in those cases, probes are not run more than once every 20 minutes.
  • Performance metadata is collected by performance monitors at the following intervals:
    • Every 5 minutes for IBM block storage systems
    • Every 5 minutes for Dell EMC Unity storage systems
    • Every 5 minutes for Hitachi VSP storage systems
    • Every 5 minutes for NetApp storage systems that are running ONTAP 9
    • Every 5 minutes for Pure storage systems
    • Every 15 minutes for other Dell EMC block storage systems.
    Restriction: Performance metadata is not collected for IBM Cloud Object Storage.
  • When you add storage systems that manage only file storage or storage systems that manage only object storage, you configure the schedule for collecting asset, capacity, and configuration metadata. For IBM Storage Scale 4.1.1 or later, if it is configured to collect node and file performance metadata, you can configure the schedule for collecting performance metadata.
  • When you add chassis for monitoring, configuration and status metadata is automatically collected for the related fabrics and switches. By default, configuration and status metadata is collected once every 24 hours and performance metadata is collected every 5 minutes. Event data is also received from switches when the configuration or status changes, so you can monitor the current state and health of a switch.
  • When you add vCenter Servers for monitoring, configuration and status metadata is automatically collected for their managed hosts and virtual machines. By default, configuration and status metadata is collected once every 24 hours and performance metadata is collected every 5 minutes.
To check the status metadata collection for a device, complete the following steps:
Device Instructions
Block storage (configuration, capacity, and performance)
  1. From the Resources menu, click Block Storage Systems.
  2. Check the value that is shown in the Data Collection column.
File and object storage (configuration, capacity, and status)
  1. From the Resources menu, click File Storage Systems or Object Storage Systems.
  2. For configuration, capacity, and status metadata, check the value that is shown in the Probe Status column.
IBM Storage Scale (performance)
  1. From the Resources menu, click File Storage Systems.
  2. For performance metadata, check the value that is shown in the Performance Monitor Status column.
Switches (configuration, capacity, status, and performance)
  1. From the Resources menu, click Switches.
  2. Check the value that is shown in the Data Collection column.
Hosts
  1. From the Resources menu, click Hosts.
  2. Check the value that is shown in the Data Collection column.

For block storage, switches, and hosts, the value in Data Collection column is an aggregate of the values for Probe Status and Performance Monitor Status. You can see the Data Collection column status as "Running" only if the Probe Status configuration and capacity collection status is "Successful" and Performance Monitor Status is "Running". If the Data Collection status is something other than "Running", have a look on Probe Statusand Performance Monitor Status column to find out the real problem.
