I am dealing with the known Cisco bug for Excessive logging of "vpn:vpn [INFO] device" messages in /var/log/messages file. It is filling our ingestion cap. I have tried numerous ways to block this from being ingested but nothing has worked(adding filter and log). Below is my syslog-ng.conf and I am looking for any advice to stop the "vpn:vpn [INFO] device" messages from being sent. There are no syslog ids for this either so blocking it from FMC also isn't working source s_sys { system(); internal(); # udp(ip(0.0.0.0) port(514)); }; destination d_cons { file("/dev/console"); }; destination d_mesg { file("/var/log/messages"); }; destination d_auth { file("/var/log/secure"); }; destination d_mail { file("/var/log/maillog" flush_lines(10)); }; destination d_spol { file("/var/log/spooler"); }; destination d_boot { file("/var/log/boot.log"); }; destination d_cron { file("/var/log/cron"); }; destination d_kern { file("/var/log/kern"); }; destination d_mlal { usertty("*"); }; filter f_kernel { facility(kern); }; filter f_default { level(info..emerg) and not (facility(mail) or facility(authpriv) or facility(cron)); }; filter f_auth { facility(authpriv); }; filter f_mail { facility(mail); }; filter f_emergency { level(emerg); }; filter f_news { facility(uucp) or (facility(news) and level(crit..emerg)); }; filter f_boot { facility(local7); }; filter f_cron { facility(cron); }; #log { source(s_sys); filter(f_kernel); destination(d_cons); }; log { source(s_sys); filter(f_kernel); destination(d_kern); }; log { source(s_sys); filter(f_default); destination(d_mesg); }; log { source(s_sys); filter(f_auth); destination(d_auth); }; log { source(s_sys); filter(f_mail); destination(d_mail); }; log { source(s_sys); filter(f_emergency); destination(d_mlal); }; log { source(s_sys); filter(f_news); destination(d_spol); }; log { source(s_sys); filter(f_boot); destination(d_boot); }; log { source(s_sys); filter(f_cron); destination(d_cron); }; # Source additional configuration files (.conf extension only) @include "/etc/syslog-ng/conf.d/*.conf" # vim:ft=syslog-ng:ai:si:ts=4:sw=4:et: # # source s_src { udp( port(514)); tcp( port(514));}; Confidentiality Notice: This message is confidential, intended only for the named recipient(s) and may contain information that is privileged, attorney work product or exempt from disclosure under applicable law.
