Re: [SR-Users] Manage blacklisting on network errors

Hello, you probably want to check the dispatcher module docs out for this ds_mark_dst(..) function. You find also some RPC commands to e.g. inspect on shell. You can also try the event-routes documented there to log some info. https://kamailio.org/docs/modules/stable/modules/dispatcher.html#dispatcher… Cheers, Henning -- Henning Westerholt – https://skalatan.de/blog/ Kamailio services – https://gilawa.com<https://gilawa.com/> From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of Marat Gareev Sent: Thursday, September 9, 2021 8:02 PM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Subject: [SR-Users] Manage blacklisting on network errors Hello! I have a simple config for routing requests with failover and blacklisting on 408, 480 and 503 codes from servers. This is a part of config: # Wrapper for relaying requests route[RELAY] { # the base event routes t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); t_on_failure("MANAGE_FAILURE"); if (!t_relay()) { sl_reply_error(); } exit; } # Manage incoming replies onreply_route[MANAGE_REPLY] { xlog("L_NOTICE", "$rr ($rs) [$cs] ($ci) $si:$sp - $ua\n"); if ( t_check_status("(503)|(408)|(480)") ) { xlog("L_WARN", "Server will be blacklisted: $si:$sp ($rs)\n"); } } # Manage failure routing cases failure_route[MANAGE_FAILURE] { if ( !t_check_status("(503)|(408)|(480)") ) { exit; } ds_mark_dst("IP"); # blacklist if (t_is_canceled()) exit; if (!ds_next_domain()) { send_reply("503", "Service Unavailable"); exit; } route(RELAY); } If there is a timeout or network error on the server side, it is blacklisted. How can such cases be managed and how can they be logged? I didn't find this on the module page: https://www.kamailio.org/docs/modules/stable/modules/tm.html
