Cisco UCS Central collects and aggregates statistics data on Network, Temperature, Cooling and Power from the registered Cisco UCS domains. During Cisco UCS Central installation, you must specify a default location to store the statistics data. You can store the statistics data in the internal PostgreSQL database called "ucscentral-stats-db" or in an external database such as Oracle 11g, MSSQL, or Postgre SQL. If you have chosen internal storage as the default location during installation, the statistics data is stored only for a maximum of two weeks. If you want to retain the collected data for more than two weeks, it is recommended that you set up an external database, see External Database for Statistics.
The collected data is aggregated based on daily, hourly, weekly and real time records and stored in tables. You can run SQL query in this database to retrieve data specific to each of the report components, see Retrieving Data from the External Database. Cisco UCS Central database is the default database to store the data.
You can set up statistics collection interval using Cisco UCS Central CLI, to collect information from the registered Cisco UCS domains at a specified interval. When a new Cisco UCS domain is registered in Cisco UCS Central, Cisco UCS Central subscribes the new domain to the statistics collection interval you have specified. If you reconfigure the collection interval, the data is updated in the registered domains. The registered
Cisco UCS domains send statistics to
Cisco UCS Central based on the specified collection
Statistics collection interval can be one of the following:
Important: You can specify the statistics collection interval only in the
Cisco UCS Central CLI. You cannot set it from the
Cisco UCS Central GUI. You can view the statistics reports
only in the
Cisco UCS Central GUI and not in the
Cisco UCS Central CLI.
