Rsyslog 无法捕获远程日志

Question

我正在使用 Rsyslog 服务器配置 LogAnalyzer。我已完成 HTTP 配置。但我的 loganalyzer 仅记录来自本地主机的日志。我有点困惑在哪里配置 snmp 字符串/社区。尽管我在 MYSql 上检查过，但没有来自我的思科设备的日志。

请帮我。

# Provides TCP syslog reception
# for parameters see http://www.rsyslog.com/doc/imtcp.html
module(load="imtcp") # needs to be done just once
input(type="imtcp" port="514")

#### GLOBAL DIRECTIVES ####

# Use default timestamp format
$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat

#File syncing capability is disabled by default. This feature is usually not required,
# not useful and an extreme performance hit
#$ActionFileEnableSync on

# Include all config files in /etc/rsyslog.d/
$IncludeConfig /etc/rsyslog.d/*.conf

您能否验证您使用的防火墙是否设置为允许通过 UDP 和 TCP 流量在端口 514 上传入？如果是这样，那么暂时地禁用 SELinux 并重试。
