| Host Monitor Storage Directory | The directory where Host Monitor data is stored. The Host Monitor stores metric time series and health information. | firehose.storage.base.directory | /var/lib/cloudera-host-monitor | firehose_storage_dir | true |
| Time-Series Storage | The approximate amount of disk space dedicated to storing time series and health data. Once the store has reached its maximum size older data will be deleted to make room for newer data. The disk usage is approximate because we only begin deleting data once we've reached the limit. Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted. See the "Disk Usage" tab on the Host Monitor page for more information on how space is consumed within the Host Monitor. This tab also shows information about the amount of data retained and time window covered by each data granularity. | firehose_time_series_storage_bytes | 10 GiB | firehose_time_series_storage_bytes | false |
| Health Event Startup Policy | This setting controls whether health events are emitted when this monitoring role is started. If set to "none", then no health events are emitted. If set to "bad" then health events are emitted for subjects with bad or concerning health. If set to "all" then health events are emitted for all subjects for all health values. The default is "bad". | health.event.publish.startup.policy | bad | health_event_publish_startup_policy | false |
| Event Publication Log Quiet Time Period | To avoid producing excessive amounts of log output, the Event Publisher component of this role is limited to emitting one message per time period. This value controls the size of that time period. | health.event.publish.log.suppress.window.ms | 1 minute(s) | svcmon_event_publication_log_suppress_window | true |

| Time-Series Storage | The approximate amount of disk space dedicated to storing time series and health data. Once the store has reached its maximum size older data will be deleted to make room for newer data. The disk usage is approximate because we only begin deleting data once we've reached the limit. Note that Cloudera Manager stores time-series data at a number of different data granularities, and these granularities have different effective retention periods. Specifically, Cloudera Manager stores metric data as both raw data points and ten-minutely, hourly, six-hourly, daily, and weekly summary data points. Raw data consumes the bulk of the allocated storage space, weekly summaries the least. As such, raw data is retained for the shortest amount of time, while weekly summary points are unlikely to ever be deleted. See the "Disk Usage" tab on the Service Monitor page for more information on how space is consumed within the Service Monitor. This tab also shows information about the amount of data retained and time window covered by each data granularity. | firehose_time_series_storage_bytes | 10 GiB | firehose_time_series_storage_bytes | false |

The default is "bad". | health.event.publish.startup.policy | bad | health_event_publish_startup_policy | false |
