Is it possible to view all the configuration files on the deployment server with SOS app. I have installed the app but I am able to view only the internal configuration files. I am using the deployment server as the master in clustering .
No. The S.o.S configuration file viewer is not designed to review the configuration located in a deployment server's app repository. It is designed to review the live configuration running on the search-head where the app is installed as well as on any search peers reachable by distributed search.
In addition to this, I need to state that:
It is unsupported to run the Deployment Server service on a Cluster Master instance.
