Configuring tiered storage alerts

About this task

Configure tiered storage alerts to monitor data distribution and performance metrics for storage tiers. Add graphs for the following metrics:

Alerts are not supported for TIER: Max Data Age.

Prerequisites

  • For centralized configuration convenience, configure the strategy and tiers in Lifecycle Manager and run a configuration job to push the configuration to all applicable nodes.

  • Apply tiered storage to a table schema and define the maximum age of data in each tier:

    CREATE TABLE ks.tbl (k INT, c INT, v INT, PRIMARY KEY (k, c))
    WITH COMPACTION={'class':'org.apache.cassandra.db.compaction.TieredCompactionStrategy',
        'tiering_strategy': 'TimeWindowStorageStrategy',
        'config': 'strategy1',
        'max_tier_ages': '3600,7200'};

    See DSE Tiered Storage for complete details.
