ELK学习笔记之ELK分析syslog日志
0x00 配置FIlebeat搜集syslog并发送至
#配置 mv /etc/filebeat/filebeat.yml /etc/filebeat/filebeat.yml.bak vim /etc/filebeat/filebeat.yml filebeat.prospectors: - type: log enabled: true paths: - /var/log/messages fields: log_topics: syslog-1.202 max_bytes: 1048576 output.logstash: hosts: ["127.0.0.1:5044"] #启动 systemctl start filebea
0x01 配置Logstash从FIlebeat输入syslog日志并输出至Elasticsearch
#配置从beat 5044端口接收日志,且根据fields建立日志索引 vim /etc/logstash/conf.d/syslog.conf input { beats { port => 5044 } } output { if[fields][log_topics] == "syslog-1.202" { elasticsearch { hosts => ["192.168.1.202:9200"] index => "syslog-1.202-%{+YYYY.MM}" } } } #启动服务 systemctl start logstash
0x02 Troubleshooting
#日志排查 tailf /var/log/logstash/logstash-plain.log tailf /var/log/filebeat/filebeat #配置文件语法合规性排查 /usr/share/logstash/bin/logstash --path.settings /etc/logstash -f /etc/logstash/conf.d/syslog.conf --config.test_and_exit /usr/share/filebeat/bin/filebeat -c /etc/filebeat/filebeat.yml
