Hello,

I need to run two syslog-ng instances on a machine. I'm going to receive two heavy "streams" of events. The two syslog-ng's will have different configurations files. My question is: Assuming that just one syslog-ng isn't enough, this is the best way to do this? There is any drawback? Is a virtualized system (for example Xen on the same machine) a better option (isolating the syslog-ng instances and configurations)?

Well, it also depends on what you are trying to achieve, but simply because you want to run two instances of syslog-ng, I would not put them both on virtualized systems. You need to specify the configuration file, pidfile and persistent config file paths via the command line explicitly, and may need to adjust the init script, but otherwise it should be perfectly doable to run two separated instances on the same machine. -- Bazsi
