I am a newbie to syslog-ng solution. I am trying to create a common config file to be distributed across client machines in San Jose, Dallas and Dublin colos. Every colo has 1 dedicated relay which forwards log data to a central server
(SJ|DU|DA)_ client --> (SJ|DU|DA)_ relay --> SYSLOG-NG server
the clients located in these colos have sj,du & da in their hostnames eg da1xxx058, du1xxx059, sj1xxx060. I want to setup the config in a way that based on hostname the config decides what relay to connect to.
Is this possible ?
Yep, it is. One way to do it is to use filters: you set up a filter that matches each colo, and set up your destinations so that each message that matches a given colo filter, goes to the appropriate relay. Something along these lines: filter f_colo_sj { host("^sj"); }; filter f_colo_du { host("^du"); }; filter f_colo_da { host("^da"); }; destination d_relay_sj { ... }; ... log { source(s_local); filter(f_colo_sj); destination(d_relay_sh); flags(final); }; log { source(s_local); filter(f_colo_du); destination(d_relay_du); flags(final); }; ...and so on and so forth. The disadvantage here is that you need a filter and a destination for each relay, but with only 3 relays, that's bearable. -- |8]
