This topic provides guidelines for using the reporting feature in Eucalyptus.
- Eucalyptus recommends that you run reports from the data warehouse. The
Cloud Controller (CLC) generates the data. The data warehouse is a store of
the stale data exported from the CLC.
- Monitor the rate of information collected and written to the CLC database. The database
expands through usage and event-driven records. More report information stored in the CLC
database lessens the effectiveness of the CLC to perform its cloud duties. If the database gets
too large, export the data to the data warehouse then delete the data from the CLC.
- Be careful about deleting data in the CLC. If you delete data in the CLC
after you export it, you should use the data warehouse to generate all
future reports. This ensures that you have a comprehensive picture of your
cloud data.
- You can't import data from different clouds into the same data
warehouse.
