Methods and apparatus are described for collecting and storing large volumes of time series data. For example, such data may comprise metrics gathered from one or more large-scale computing clusters over time. Data are gathered from resources which define aspects of interest in the clusters, such as nodes serving web traffic. The time series data are aggregated into sampling intervals, which measure data points from a resource at successive periods of time. These data points are organized in a database according to the resource and sampling interval. Profiles may also be used to further organize data by the types of metrics gathered. Data are kept in the database during a retention period, after which they may be purged. Each sampling interval may define a different retention period, allowing operating records to stretch far back in time while respecting storage constraints.
