Question

我已经通过NXlog成功将日志发送到Graylog2。但是，NXlog和Graylog2都运行在同一台服务器上。现在我想通过NXlog将日志从另一台服务器发送到Graylog2，但根本不能正常工作。你能帮帮我吗？这是我的NXlog配置：

User i_cdp
Group int

Panic Soft

#define CERTDIR /opt/cdp/nxlog/opt/var/lib/nxlog/cert
define CONFDIR /opt/cdp/nxlog/opt/var/lib/nxlog
define LOGDIR /opt/cdp/nxlog/opt/var/log/nxlog
define LOGFILE "%LOGDIR%/nxlog.log"

SpoolDir /opt/cdp/nxlog/opt/var/spool/nxlog

# default values:
PidFile /opt/cdp/nxlog/opt/var/run/nxlog/nxlog.pid
CacheDir /opt/cdp/nxlog/opt/var/spool/nxlog

<Input in>
    Module      im_file
    File       "/opt/cdp/jboss-eap/jboss/standalone/log/*.log*"
    Exec if $raw_event =~ /(\d\d\d\d\-\d\d-\d\d \d\d:\d\d:\d\d)/ $EventTime = parsedate($1);
    Exec $Hostname = 'bsul0850';
    Exec if $raw_event =~ /ERROR/ $SyslogSeverityValue = 3; \
    else $SyslogSeverityValue = 6;
    Exec $FileName = file_name();
    Exec if $raw_event =~ /WARN/ $Message = 'IMPORTANT!! ' + $raw_event;
    Exec $SourceName = 'jboss';

        Exec    if (file_exists(%LOGFILE%) and (file_size(%LOGFILE%) >= 5M)) file_cycle(%LOGFILE%, 8);
    </Schedule>

    # Rotate our log file every week on sunday at midnight
    <Schedule>
        When    @weekly
        Exec    if file_exists(%LOGFILE%) file_cycle(%LOGFILE%, 8);
    </Schedule>
</Extension>

我打开了端口12009，用于连接Nxlog的服务器和带有Graylog2的服务器之间的连接。然后我在Graylog-Gui上配置了一个输入： Input(GELF UDP on Port 12009) 但是，我检查连接，我只得到：

[i_cdp@bsul0850 etc]$ ssh -vvv bsul0959 -p 12009
OpenSSH_5.3p1, OpenSSL 1.0.1e-fips 11 Feb 2013
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to bsul0959 [10.41.66.84] port 12009.
debug1: connect to address 10.41.66.84 port 12009: Connection refused
ssh: connect to host bsul0959 port 12009: Connection refused

它说，拒绝了。所以有一种联系，因为我没有超时或类似的东西，我是对的吗？ Graylog服务器不接受连接。那么，我的配置有什么问题？ Graylog没有收到任何东西。

提前谢谢你：）

使用ssh检查开放端口有点奇怪。请注意，ssh使用TCP并且Graylog正在侦听UDP端口，因此您需要以不同方式进行诊断。

将NXLog连接到Graylog2
