Reading OS logs from a cluster indexer node is controlled by the master node $SPLUNK_HOME/etc/master-apps/_cluster/local/inputs.conf , but that only affects the indexer nodes, not the master node itself.
If I configure outputs.conf in $SPLUNK_HOME/etc/system/local/ on the master node, will it then forward everything from the master node or only the monitored paths specified in inputs.conf ?
The thing is that I only want to forward OS logs (under /var/log or any other specified file), not the internal stuff from Splunk on the master node itself.
I would suggest a manual edit or deployment of *NIX App. Using deployment server.
