Track repaired SSTables for incremental repairs
Configure dashboard graphs to visually monitor the progress of repaired SSTables at the node and table levels during an incremental repair.
The DSE OpsCenter Repair Service uses the SSTables Repaired metrics to determine whether it should run incremental repairs, based on the configured value of the incremental_threshold option.
Add graphs for the following metrics:
-
Percent Data Repaired [percentage-repaired]
Percentage of data (uncompressed) marked as repaired across all non-system tables on a node. Tables with a replication factor of 1 are excluded.
-
TBL: Percent Data Repaired [cf-percentage-repaired]
Percentage of data (uncompressed) marked as repaired for a given table on a node. This metric is only meaningful for replication factor > 1.
The SSTables Repaired metrics are meaningful only for keyspaces that have a replication factor of 2 or greater.
For a keyspace that has an RF=1, the percentage repaired is 0.

Configure tables to include in incremental repairs. Adjust the incremental threshold if necessary. For more information, refer to Configure incremental repairs.

Click Cluster, and then click Dashboard.
-
Clone the Default preset tab and give it a name such as
Repairs. -
Click Add Graph.
-
On Add Metric, select the SSTables Repaired metric.
-
Select the nodes to monitor from the Node list.
-
Click Add Metric.
-
Click Add Graph.
-
On Add Metric, select the TBL: SSTables Repaired metric.
-
Select the tables to monitor from the Tables list.
-
Repeat this procedure for all DSE clusters you need to monitor for incremental repairs.
