In datastax cassandra 5.1, why is dsetool missing insights_config command?

Question

running dsetool insights_config on the DataStax Cassandra node returns Unknown command: insights_config whereas the documentation states that this command should be present.

Answer 1

DSE Metrics Collector was introduced in the DSE 5.1.14 (current version is 5.1.17) - make sure that you're using version that has this functionality. In my setup it works just fine:

(dse-5.1.17) ...\>dsetool insights_config --show_config
{
  "mode" : "DISABLED",
  "config_refresh_interval_in_seconds" : 30,
  "metric_sampling_interval_in_seconds" : 30,
  "data_dir_max_size_in_mb" : 1024,
  "node_system_info_report_period" : "PT1H"
}
