td_agent_bit_buffer_type filesystem

The back pressure buffer type for logs - store in memory or back up to disk. In most conditions, it would not be required to change the default value; but if high disk i/o is noticed, change the setting.

Valid values are memory and filesystem.

td_agent_bit_metrics_buffer_type filesystem The back pressure buffer type for metrics - store in memory or back up to disk. In most conditions, it would not be required to change the default value; but if high disk i/o is noticed, change the setting.

Valid values are memory and filesystem.

Note: td_agent_bit_buffer_type and td_agent_bit_metrics_buffer_type properties can be set at deployment time or can be modified using the Cluster Manager CLI.
Example: 
cm ls components

clustermanager set config --componentType <component type from ls components> --componentId <component id from ls components> --prop td_agent_bit_buffer_type --value filesystem
