The only thing that would limit the number of instances that I am aware of are conflicts for opening things like network ports, connections to databases, maybe FIFOs, etc. I would look at that as a place to start. What kind of errors are you getting when you try to start the second instance? Jim ---- David Campeau <David.Campeau@tn.gov> wrote:
Hello,
I've been using syslog-ng to filter syslog before forwarding on to a log collector. However, I need to spin up a second instance for testing purposes. I've found a little bit of information on-line, but it hasn't completed the entire picture.
This is the command used to start up the 2nd instance. I'm pointing to separate .conf .persist .pid and .ctl files -- However, it's still not working. I suspect the issue is due to OS log sources. How do a change log sources?
syslog-ng --cfgfile=/usr/local/bin/syslog-ng-Second-Instance/syslog-ng.conf --persist-file=/usr/local/bin/syslog-ng-Second-Instance/syslog-ng.persist --pidfile=/usr/local/bin/syslog-ng-Second-Instance/syslog-ng.pid --control=/usr/local/bin/syslog-ng-Second-Instance/syslog-ng.ctl &
This is the upper part of the syslog-ng.conf file for the 2nd instance I wish to run.
@version: 3.3.4 @include "scl.conf" options { time-reap(30); mark-freq(10); keep-hostname(yes); chain-hostnames(no); use-dns(no); ## log-fifo-size(500000); ## Tuning Options ## flush_lines(10000); ## Tuning Options ## flush_timeout(10000); ## Tuning Options };
source s_second_instance { syslog(transport("udp") port("518")); #### Will receive test syslog on port 518 };
destination d_syslog_udp { syslog("10.X.X.X" transport("udp") port("514") throttle(4000) ); };
I'm hoping someone has experience or has seen information on how to run a 2nd instance on the same box.
Best Regards,
David
