Adrian,
It is not possible to keep such logs. They are just part stored in the client and not in the server. Also, one cannot set retention for persistent logs on a duration basis. These are basically size-based.
What you can do is:
- Keep a client opened.
- Use Server.log and not System.log in your workflows. This logs are created in the Server and can be found in the events tab from the Workflow or any of it's category (folder).
To add, in the configuration you have two parameters: General tab -> Advanced configuration:
Max number of events
Max number of runs
These will set how much entries per workflow will be kept and how much finished runs will be kept. Purge is done on a hourly basis.
Settings these to zero will retain all logs, beware though that the database will grow indefinitely and performance will therefore degrade. But, these settings only apply for Workflow events, if you are talking about Execution logs (just shown under the execution logs tab when a Workflow execution is selected), this settings don’t apply.
I hope the above info is useful.
