Configuring tiered storage metric graphs
About this task
Configure tiered storage graphs to visually monitor data distribution and performance metrics for storage tiers. Add graphs for the following metrics:
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 Cluster > Dashboard.
-
Clone the Default preset tab and give it a name such as Tiered storage.
-
Click Add Graph.
The Add Metric dialog appears.
-
Complete the dialog for each metric graph:
-
Choose the TIER metric from the Metric list.
-
Choose the nodes to monitor from the Node list.
-
Choose the tables to monitor from the Tables list.
-
Choose the tiers to monitor from the Tiers list.
-
Click Add Metric.
The graph appears in the dashboard.
-
Repeat these steps for each tier metric and the corresponding nodes, tables, or tiers that you need to monitor.
