Configuring Service Monitor Data Storage
The Service Monitor stores time series data and health data, Impala query metadata, and YARN application metadata.
By default, the data is stored in /var/lib/cloudera-service-monitor/
on the
Service Monitor host. You can change this by modifying the Service Monitor Storage
Directory configuration (firehose.storage.base.directory
). To
change this configuration on an active system, see Moving Monitoring Data on an Active
Cluster.
- Time-series metrics and health data - Time-Series Storage
(
firehose_time_series_storage_bytes
- 10 GB default, 10 GB minimum) - Impala query metadata - Impala Storage (
firehose_impala_storage_bytes
- 1 GB default) - YARN application metadata - YARN Storage (
firehose_yarn_storage_bytes
- 1 GB default)
For information about how metric data is stored in Cloudera Manager and how storage limits impact data retention, see Data Granularity and Time-Series Metric Data.
The default values are small, so you should examine disk usage after several days of activity to determine how much space is needed.
