Configure tiered storage alerts

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'};

Click Alerts from the main OpsCenter monitoring menu.

Click Manage Alerts > Add Alert.

In the Notify me when menu, select Advanced > DSE > TIER: metric name.

Specify the notification criteria, the table, and the tier on which to notify as well as the notification frequency.

Click Save Alert.
