Monitor in-memory usage from within OpsCenter. The In-Memory option is a DataStax Enterprise feature only. More information about creating or altering a table to use in-memory is available in the DataStax Enterprise documentation DSE In-Memory section.
A metric and an alert are available for monitoring in-memory usage:
- The In-Memory Percent Used alert is available to configure for DataStax Enterprise nodes. If the in-memory usage exceeds the configured threshold, an alert is fired. Investigate the alert and adjust the memory threshold configuration as appropriate.
- The In-Memory Percent Used metric is available to
add as a separate
graph in the dashboard of OpsCenter versions 5.1.2 and later.
A visual cue (an In-Memory label next to the table name) in the Keyspaces area of OpsCenter indicates whether a table uses the In-Memory option. Click
