DSE Metrics Collector configuration examples
These configuration examples show how to:
-
View the current configuration
-
Enable and disable metrics collection
-
Adjust the interval of metrics collection
-
Adjust the interval to refresh configuration changes
-
Set the maximum size of the local data directory (2 GB limit)
-
Adjust the node system information reporting period
After you make configuration changes with dsetool insights_config, you must disable and then re-enable DSE Metrics Collector to read the configuration file again.
Examples
View the current DSE Metrics Collector configuration
dsetool insights_config --show_configThe results of the default configuration:
{
"mode" : "ENABLED_WITH_LOCAL_STORAGE",
"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"
}Enable metrics collection when collectd is configured to report to a real-time monitoring system
dsetool insights_config --mode ENABLED_NO_STORAGEEnable metrics collection with local storage
dsetool insights_config --mode ENABLED_WITH_LOCAL_STORAGEConfigure 1500 MB for the DSE Metrics Collector local data directory
dsetool insights_config --data_dir_max_size_in_mb 1500|
The maximum size of the local data directory must not exceed 2 GB. |
The default directory for local storage is /var/lib/cassandra/insights_data.
To change the directory to store collected metrics, see Configuring the data and log directories for DSE Metrics Collector.
Change the node system reporting duration to 1 week
Use an ISO-8601 time duration string.
dsetool insights_config --node_system_info_report_period P1WDisable metrics collection
dsetool insights_config --mode DISABLEDConfigure the metric sampling interval for 60 seconds
dsetool insights_config --metric_sampling_interval_in_seconds 60Configure 120 seconds for the configuration refresh interval
Push configuration changes to all nodes in the cluster every 2 minutes:
dsetool insights_config --config_refresh_interval_in_seconds 120|
After you make configuration changes with dsetool insights_config, you must disable and then re-enable DSE Metrics Collector to read the configuration file again. Wait at least 30 seconds for the changes to propagate to all nodes. |
