Monitoring ILM evaluations

You can track ILM evaluation attributes to monitor how objects are being managed by the StorageGRID Webscale system.

Before you begin

You must be signed in to the Grid Management Interface using a supported browser.

About this task

Objects are managed by applying the ILM policy defined for your StorageGRID Webscale system. The ILM policy and associated ILM rules determine how many copies are made, how those copies are made, the appropriate placement, and the length of time each copy is retained.

Steps

  1. Select Grid.
  2. Select deployment > Overview > Main.

  3. In the ILM Activity section, review the key attributes for ILM evaluations:
    Awaiting - All
    The total number of objects awaiting ILM evaluation.
    Awaiting - Client
    The total number of objects awaiting ILM evaluation from client operations (for example, ingest).
    Scan Rate
    The rate at which objects in the grid are scanned and queued for ILM.
    Scan Period - Estimated
    The estimated time to complete a full ILM scan of all objects.
    Note: A full scan does not guarantee that ILM has been applied to all objects.
    Awaiting - Evaluation Rate
    The current rate at which objects are evaluated against the ILM policy in the grid.
    Repairs Attempted
    The total number of object repair operations for replicated data that have been attempted. This count increments each time an LDR tries to repair a high-risk object. High-risk ILM repairs are prioritized if the grid becomes busy.
    Note: The same object repair might increment again if replication failed after the repair.
