I am thinking about how this would be done and whether Hyrax provide any of this information, or another tool within the service can scan the logs and obtain a standard of information.<br /> <br /> === Catalog Statistics ===<br /> ---------------<br /> Overall storage of accessible data (GB)<br /> Overall number of data files<br /> Overall number of data sets (groups of files from metadata structure, ideal for aggregations)<br /> Overall number of aggregated data sets<br /> Overall number of virtual data sets<br /> Overall number of CF compliant data sets<br /> ...<br /> <br /> === Catalog of data set statistics ===<br /> -----------------------<br /> Storage of accessible data (GB)<br /> Number of data files<br /> Time range of data<br /> Spatial range of data<br /> Number of unique variables in data files<br /> CF compliant data set<br /> Aggregation of data set<br /> ...<br /> <br /> <br /> === Data service statistics ===<br /> --------------------<br /> Number of unique visitors per day<br /> List of unique visitors names, ip address, host name, and application name<br /> Number of data requests per service (catalog, opendap, wms, ...)<br /> Number of data volume delivered per service<br /> List of application name, user name, and data-size delivered for data request<br /> Number of requests exceeding data request size thresholds<br /> List of unique visitors names, ip address, host name, and application name exceeding threshold<br /> Number of data request served asynchronously<br /> Number of data request using server-side processing<br /> ...<br /> <br /> <br /> === Service statistics per data set ===<br /> ----------------------<br /> Number of unique visitors per day<br /> List of unique visitors names, ip address, host name, and application name<br /> Number of data requests per service (catalog, opendap, wms, ...) per data set<br /> Number of data volume delivered per service per data set<br /> List of application name, user name, and data-size delivered for data request<br /> ...<br /> <br /> I’m thinking about this for an implementation plan and data service management.</div>
