This document explains how to install and configure an environment for analyzing SAP Web Dispatcher (WD) logs with logstash, elasticsearch and Kibana under Linux. Kibana 3 needs a running web server. The example shown here is using nginx, but won’t detail how to set up nginx. Components referred to in Read more…
SMP 3 connects to a authentication provider using SSL. For SMP 3 to be able to connect successfully to the SSL enabled backend service, the server certificate of that backend must be installed in SMP 3. This means to install the certificate into the keystore used by SMP 3. The Read more…
