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.

Procedure

Click Alerts from the main OpsCenter monitoring menu.

The Active Alerts dialog appears.
Click Manage Alerts > Add Alert.

The Add Alert dialog appears.
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.
