"ts" stands for Time Series. This is where the Service Monitor role in the Management Service stores data for Time Series information. You can configure retention policies in the configuraiton of your Service Monitor role. There's also a page to help you understand the disk usage in detail, as described below: Time-Series Storage firehose_time_series_storage_bytes 10 GiB 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.
