3.1. Prerequisites to installing syslog-ng PE The syslog-ng Premium Edition 7 Administrator Guide
The binary installer packages of syslog-ng Premium Edition include every required dependency for most platforms, only the
ncurseslibrary is required as an external dependency (syslog-ng PE itself does not use the ncurses library, it is required only during the installation).
For Java-based destinations (for example, Elasticsearch, Apache Kafka, HDFS), Java must be installed on the host where you use such destinations. Typically, this is the host where you are running syslog-ng PE in server mode.
DO NOT install syslog-ng PE on an NFS-mounted partition
DO NOT store the runtime files (for example, the configuration or the persist file) of syslog-ng PE on an NFS-mounted partition
