If all of the solaris hosts log to a different port or IP address, then there is no need to place hosts into the syslog configuration file. Every log message sent to the special IP/port is assumed to be from a solaris host. Then you just store them into a destination of your choosing. Evan. On 11/02/2015 02:18 PM, vijay amruth wrote:
@Evan, Right now we are just adding the hosts manually to the syslog file if there is way by which I don't need to add the hosts manually to the file.

Before I get too deep into how this is done, can I ask why you want to separate your logs for solaris and linux?

Thank you Evan.
Right now, we add a solaris server everytime we spin one,
its like this,
filter f_solaris { host('x.x.x.x') or host('x.x.x.2') or host('x.x.x.3') or host('x.x.x.4') or host('hostname1) or (hostname2) }
So everytime we spin a server we just go and add it manually to the config file, either with its host name or the ip. I want to be able to automate with filter functions and or regex so that I don't have to add manually to the config file on the server everytime. There is a similar config for linux hosts too
Hope I am clear. Appreciate you taking your time out for this.

The syslog server has to listen on the ipaddress:port combination. The solaris hosts need to syslog to the new ipaddress:port combination.
Since I don't know how you are processing your log lines in your syslog-ng configuration it is difficult to provide a lot of guidance, but here are a couple of examples.
---- option #1 Using a completely different source. - you must fill in the IP addresses and port numbers
source s_regular_syslog { tcp(localip(regularIP) port(regularPort) max_connections(5000) log_fetch_limit(20000) log_iw_size(1000000) tags("regular_syslog") ); };
source s_solaris_syslog { tcp(localip(solarisIP) port(solarisPort) max_connections(5000) log_fetch_limit(20000) log_iw_size(1000000) tags("solaris_syslog") ); };
log { source(s_regular_syslog); destination(d_regular_destination); }; log { source(s_solaris_syslog); destination(d_solaris_syslog); };
---- option #2 Using a tagged source. - you must fill in the IP addresses and port numbers
source s_all_syslog { tcp(localip(regularIP) port(regularPort) max_connections(5000) log_fetch_limit(20000) log_iw_size(1000000) tags("regular_syslog") ); tcp(localip(solarisIP) port(solarisPort) max_connections(5000) log_fetch_limit(20000) log_iw_size(1000000) tags("solaris_syslog") ); };
filter f_solaris { tags("solaris_syslog"); };
log { source(s_all_syslog) log { filter(f_solaris); destination(d_solaris_syslog); flags(final); }; log { destination(d_regular_destination); }; };
I hope that gives you the basics of what is needed.

Thank you Evan, great idea! Can we achieve this with regex on syslog-ng.conf file on the server side?

You could use a second interface on the syslog servers and configure the solaris servers to use this alternate IP address. You could also use a different port. Then you could tag the source with "solaris" and then use the tag filtering to separate those message out of the mix.
Just my $0.02

Thank you fo rthe reply Balazs.
Can we use filter functions like this below ?
filter f_solaris { host('uname == solaris') }
My idea is to identify solaris servers.
Thanks all, ~Vj

Well, probably the only sensible way is to filter based on IP addresses.

Hello All,
We are drawing logs from several hosts which include solaris(10,11) , linux (centos, ubuntu, rhel) into syslog servers, I want to be able to separate solaris logs, is there any pattern we can match for solaris logs that you may know ?
Thanks, Vijay Amrut.
