如何在elasticsearch中查看Logstash打到elasticsearch的数据

# cat syslog02.conf 
#filename:syslog02.conf #注意这个是要用#号注释掉
input{
    file{
        path => ["/var/log/*.log"]
    }
}
output{
    elasticsearch {
        hosts => ["12x.xx.15.1xx:9200"]
    }
}

查看配置文件是否有问题:

# ../bin/logstash -f syslog02.conf -t
Sending Logstash's logs to /usr/local/logstash/logs which is now configured via log4j2.properties
[2016-12-01T09:54:46,512][FATAL][logstash.runner          ] The given configuration is invalid. Reason: Expected one of #, input, filter, output at line 1, column 1 (byte 1) after

在output->elasticsearch下增加一个index配置:

cat syslog02.conf 
#filename:syslog02.conf
input{
    file{
        path => ["/var/log/*.log"]
    }
}
output{
    elasticsearch {
        hosts => ["123.57.15.154:9200"]
        index => "syslog02_log"
    }
}

再次简测配置文件:

# ../bin/logstash -f syslog02.conf -t
Sending Logstash's logs to /usr/local/logstash/logs which is now configured via log4j2.properties
Configuration OK
[2016-12-01T11:40:56,791][INFO ][logstash.runner          ] Using config.test_and_exit mode. Config Validation Result: OK. Exiting Logstash

启动并在后台执行:

# ../bin/logstash -f syslog02.conf &
