Edit the
dse.yamlfile. -
In the
dse.yamlfile, set the enabled option forcluster_summary_stats_optionstotrue.# Cluster summary stats options cluster_summary_stats_options: enabled: true refresh_rate_ms: 10000 -
Optional: To control how often the statistics are refreshed, increase or decrease the
refresh_rate_msparameter.The
refresh_rate_msspecifies the length of the sampling period, that is, the frequency with which this data is updated.
