This page allows LDAS users to obtain a graphical view of the numeric data inserted into a database table within a specified time. Only columns with numeric values can be selected.

View Database filters

  1. Select a database among the list.
  2. Select a table among the list.
  3. Select a time field among the list. Currently only insertion time is allowed.
  4. Select a column among the list. The list consists of columns with numeric data only.
  5. Specify the time ranges: one easy way is to select one of the time options: last minute, last hour, last day to get some time in the entry fields and then modify the times to your desire range.
  6. If you need to edit the resultant SQL, hit EDIT and enter your changes in text column. Your changes will be appended to the current SQL text. If you enter invalid text, the SQL may result in errors.
  7. Submit request to server by hitting the SUBMIT button.

Response:

The request is submitted as an LDAS getMetaData job request. Since the getMetaData has a limit on the number of rows that can be retrieved at one time, multiple requests will be automatically submitted to accumulate all the data for the entire time period and then returned to cmonClient. If you need to abort the request, select a request from the list and hit ABORT REQUEST. Your request will be aborted when the getMetaData job has completed instead of continuing with more request for the time period. Note that No partial results are returned from an abort..
