我正在尝试将相同的日志流发送到两个不同的弹性搜索索引，因为每个索引具有不同角色的用户。

我也使用文件作为目的地。这是一个示例：

2021-02-12T14:00:00+01:00 192.168.89.222 <30>1 2021-02-12T14:00:01+01:00 sonda filebeat 474 - - 2021-02-12T14:00:01.364+0100    DEBUG   [input] input/input.go:152      Run input
2021-02-12T14:00:00+01:00 192.168.89.222 <30>1 2021-02-12T14:00:01+01:00 sonda filebeat 474 - - 2021-02-12T14:00:01.364+0100    DEBUG   [input] log/input.go:191        Start next scan
2021-02-12T14:00:00+01:00 192.168.89.222 <30>1 2021-02-12T14:00:01+01:00 sensor filebeat 474 - - 2021-02-12T14:00:01.364+0100    DEBUG   [input] log/input.go:421        Check file for harvesting: /opt/zeek/logs/current/weird.log

当我只为 elasticsearch-http 使用一个目标时，配置了两个中的任何一个，一切正常，但是当同时使用两个目标时，syslog-ng 无法启动并且 systemcl 抱怨。

这是我的/etc/syslog-ng/syslog-ng.conf文件：

@version: 3.27
@include "scl.conf"
options { chain_hostnames(off); flush_lines(0); use_dns(no); use_fqdn(no);
      dns_cache(no); owner("root"); group("adm"); perm(0640);
      stats_freq(0); bad_hostname("^gconfd$");
};
source s_net { 
    udp( 
        ip(0.0.0.0) 
        port(514)
        flags(no-parse)
    );
};
log {
    source(s_net);
    destination(d_es);
    destination(d_es_other_index);   ######## comment this to avoid the error
    destination(d_file);
};

template t_demo_filetemplate {
    template("${ISODATE} ${HOST} ${MESSAGE}\n");
};

destination d_file {
    file("/tmp/test.log" template(t_demo_filetemplate));
};

destination d_es{
    elasticsearch-http(
        index("syslog-ng-${YEAR}-${MONTH}-${DAY}")
            url("https://192.168.89.44:9200/_bulk" "https://192.168.89.144:9200/_bulk")
        type("")
            user("elastic")
            password("password")
            batch_lines(128)
            batch_timeout(10000)
            timeout(100)
            template("$(format-json --scope rfc5424 --scope nv-pairs --exclude DATE --key ISODATE)")
        time-zone("UTC")
        tls(
            ca-file("/root/elastic_certs/elastic-ca.crt")       
            cert-file("/root/elastic_certs/elastic.crt")
            key-file("/root/elastic_certs/elastic.key")
            peer-verify(no)
        )
    );
};

destination d_es_other_index{
    elasticsearch-http(
        index("otherindex-${YEAR}-${MONTH}-${DAY}")
            url("https://192.168.89.44:9200/_bulk" "https://192.168.89.144:9200/_bulk")
        type("")
            user("elastic")
            password("password")
            batch_lines(128)
            batch_timeout(10000)
            timeout(100)
            template("$(format-json --scope rfc5424 --scope nv-pairs --exclude DATE --key ISODATE)")
        time-zone("UTC")
        tls(
            ca-file("/root/elastic_certs/elastic-ca.crt")
            cert-file("/root/elastic_certs/elastic.crt")
            key-file("/root/elastic_certs/elastic.key")
            peer-verify(no)
        )
    );
};

使用两个弹性搜索目标时出现的错误（journalctl -xe 似乎没有显示相关信息）：

# systemctl restart syslog-ng.service
Job for syslog-ng.service failed because the control process exited with error code.
See "systemctl status syslog-ng.service" and "journalctl -xe" for details.

还有我的 syslog-ng 信息：

$ syslog-ng --version

有没有办法同时做这两个弹性搜索索引？
