We are using Striim to replicate data from Oracle to BigQuery

I would like to know how can I find out for UI

  1. current archived logs being mined by log miner
  2. The current DDL ( LCR , logical count record ) being processed) 
  3. Number of DDLs or LCR in the current Transaction or SCN

Thank You

 In the UI, go to the Console by clicking ‘Console’ in the top nav.

 

Enter the command “mon <namespace>.<component name> [ <node> ]” for your OracleReader. 

For an OracleReader source, output will include the following:
