Configuring the RRD Database

To configure the RRD database using Fabric Manager Web Server, follow these steps:

  1. Choose Admin > Configure.
  2. Click Database in the left navigation pane.
  3. Enter the number of days to collect samples at 5-minute intervals in the top row of the Days column.
  4. Enter the number of days to collect samples at 30-minute intervals in the second row of the Days column.
  5. Enter the number of days to collect samples at 2-hour intervals in the third row of the Days column.
  6. Enter the number of days to collect samples at 1-day intervals in the bottom row of the Days column.
  7. Note     As of Cisco SAN-OS Release 3.1(1) and later, you can configure the sampling interval for ISLs. Select a sampling interval from the ISLs drop-down list.

  8. Click Apply to apply your changes, or click Defaults to reset the file sizes to the default values.
  9. If you are applying new values, or if the current values are not the default values, you see a message indicating that conversion of the RRD files will take a certain amount of time and that the database will be unavailable until then. The time it takes depends on the difference between the old and new values.

    Note     The system allows only one conversion process at a time. Once you start the conversion, the Apply and Default buttons change to Refresh and Cancel so that another process cannot be inadvertently started. This display is the same for all browsers accessing this server during this time. Click Refresh to view the latest progress of the conversion. Click Cancel to cancel the conversion job. If the job is successfully canceled, you see the Apply and Default buttons again. If the cancel is not successful, you see a message indicating that the cancellation has failed.

    If you want to perform this procedure, it is best to perform it before collecting a lot of data. Otherwise, the conversion can take a long time to complete.
