Log files

System

We have an OD receiver Unix installation installed in /opt/opendeploy, with the log files configured to use /logs/opendeploy
A log file, "od.log" is created in /opt/opendeploy, and appended to at every deploy. This is in addition to the main log file /logs/opendeploy/[servername]_odrcvr.log. We need ALL the logs to go to /logs, and no writes to occur in the installation directory. How can this be accomplished?
After a week, we now have around a thousand log files in one directory, slowing down the server. As we do need to keep the logs, the solution is not as simple as to delete them.
Is there a way to remove the unique number from the deployment name so the receiver will really append to the log files instead of creating new files? We can live with four log files for each workflow, but not four new log files for each and every time something is deployed. In other
words, is there a way to configure the name used to not be unique for each and every deploy INSTANCE?
