[syslog-ng]Locals in Syslog.

Hello. I`m working on a project where I need to set up a syslog-environment. I have about 140 servers that needs to send their syslog-info to a centralized syslog-ng server. My challenge is that I need to identify each server with their own local-value. Default, syslog has a limitation in how many locals you can define, isn`t it 8? Has anyone had experience with changing this value to whatever number; e.g 100? Regards Jon Hofstad
