Configuring tiered storage alerts

Configure tiered storage alerts to monitor data distribution and performance metrics for storage tiers.

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

Note: 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 Storagefor 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.
