使用logstash
收集系统上的日志,并使用 grok
解析日志,使用mutate
修改解析出来的字段类型、删除字段、重命名字段,最后将解析好的日主输出到 elasticsearch
中。html
vim output-es.yml
java
input { file { id => "mutate-id" path => ["/Users/huan/soft/elastic-stack/logstash/logstash/pipeline.conf/output-es/*.log"] start_position => "beginning" sincedb_path => "/Users/huan/soft/elastic-stack/logstash/logstash/pipeline.conf/output-es/sincedb.db" codec => multiline { pattern => "^\[+" negate => "true" what => "previous" charset => "UTF-8" auto_flush_interval => 2 } } } filter { grok { match => { "message" => "(?m)^\[%{INT:pid}\]%{SPACE}%{TIMESTAMP_ISO8601:createTime}%{SPACE}\[%{DATA:threadName}\]%{SPACE}%{LOGLEVEL:LEVEL}%{SPACE}%{JAVACLASS:javaClass}#(?<methodName>[a-zA-Z_]+):%{INT:linenumber}%{SPACE}-%{GREEDYDATA:msg}" remove_field => ["message"] } } mutate { convert => { "pid" => "integer" } rename => { "msg" => "message" } } # 格式化 createTime 将 源格式 转换成 目标格式 date { match => ["createTime","yyyy-MM-dd HH:mm:ss.SSS","yyyy-MM-dd HH:mm:ss.SSS"] target => "@timestamp" remove_field => ["createTime"] } } output { # 能够经过 template 或 template_name 指定es模板的名字 elasticsearch { hosts => ["http://localhost:9200","http://localhost:9201","http://localhost:9202"] user => "springboot_logstash" password => "123456" index => "springboot-%{+YYYY.MM.dd}" template_overwrite => "false" } }
elasticsearch
配置参数解析:hosts
: es
的访问地址,建议使用非master
节点。user
: 访问es的用户名。password
:访问es的密码。index
:在es中的索引名称。template
:设置本身的es模板路径。template_name
:使用es中的索引模板名称。上方的es的密码是明文的,可能存在泄漏,能够使用 logstash keystore
来解决。web
{ "error": { "root_cause": [ { "type": "security_exception", "reason": "action [indices:data/ write/bulk] is unauthorized for user [logstash_system] on indices [], this action is granted by the index privileges [create_doc,create,delete,index,write,all]" } ], "type": "secu rity_exception", "reason": "action [indices:data/write/bulk] is unauthorized for user [logstash_system] on indices [], this action is granted by the index privileges [create_doc ,create,delete,index,write,all]" }, "status": 403 }
当咱们使用系统自带的logstash_system
用户时,可能会报indices:data/write/bulk
这个操做没有权限,解决方法以下(本身新建一个用户和角色)。
