我试图排除 syslog-ng 记录某些消息，例如此 LDAP 日志条目：
Sep 18 15:18:34 myserver slapd[9682]: conn=1043 op=24 SEARCH RESULT tag=101 err=0 nentries=1 text=
我有这个 syslog-ng 过滤器，我正尝试使用它来过滤掉这些消息：
filter f_not_ldap { not match("slapd" value(PROGRAM)); };
log { source(s_udp); filter(f_not_asa); filter(f_not_dbg); filter(f_not_ldap); destination(d_messages); destination(d_logserver); };
但那些 slapd 条目仍会发送到我的远程日志服务器。有人能告诉我我做错了什么吗？我还需要做什么才能过滤掉那些 slapd 条目？
提前致谢。
编辑：这是整个 syslog-ng.conf：
@version: 3.3
@include "scl.conf"
# Syslog-ng configuration file, compatible with default Debian syslogd
# installation.
# First, set some global options.
options { chain_hostnames(off); flush_lines(0); use_dns(no); use_fqdn(no);
owner("root"); group("adm"); perm(0640); stats_freq(0);
bad_hostname("^gconfd$");
};

答案1
那是第 184 行。我将其从：
log { source(s_src); destination(d_logserver); };
到
log { source(s_src); filter(f_not_ldap); destination(d_logserver); };
现在 LDAP 日志不再进入我的日志服务器，所以这个问题现在已经解决了。
答案2
filter f_not_ldap { not match("slapd" value(PROGRAM)); };
现在应替换为：
filter f_not_ldap { not message("slapd"); };
消息从版本 2.2 开始可用
