Springboot集成syslog+logstash收集日志到ES
Springboot集成syslog+logstash收集日志到ES
1、背景
Logstash 是一个实时数据收集引擎,可收集各类型数据并对其进行分析,过滤和归纳。按照自己条件分析过滤出符合的数据,导入到可视化界面。它可以实现多样化的数据源数据全量或增量传输,数据标准格式处理,数据格式化输出等的功能,常用于日志处理。工作流程分为三个阶段:
- input数据输入阶段,可接收oracle、mysql、postgresql、file等多种数据源;
- filter数据标准格式化阶段,可过滤、格式化数据,如格式化时间、字符串等;
- output数据输出阶段,可输出到elasticsearch、mongodb、kafka等接收终端。
架构原理:springboot发出syslog日志,通过系统的rsyslog服务进行数据转发,logstash监听rsyslog端口过滤数据并发到es进行存储
2、springboot集成syslog

logback.xml文件配置
配置好日志之后,在root标签中添加appender才能生效;

<appender-ref ref="consoleLogAppender"/>
<appender-ref ref="infoFileAppender"/>
<appender-ref ref="errorFileAppender"/>
<appender-ref ref="SYSLOG"/>
</root>
</configuration>
SyslogAppender是syslog的配置:
syslogHost:指的是syslog服务器的主机名/IP地址
port:syslog服务器的监听端口,默认为514 udp
facility:标识消息的来源
suffixPattern:描述日志的格式
3、rsyslog接收springboot应用的日志
1、服务器安装rsyslog服务
apt install rsyslog 安装
systemctl start rsyslog 启动服务
systemctl status rsyslog 查看服务状态
systemctl enable rsyslog 设置rsyslog服务器在启动时自动运行
2、配置rsyslog.conf
rsyslog的配置文件位于:/etc/rsyslog.conf
global(workDirectory="/var/lib/rsyslog")
module(load="builtin:omfile" Template="RSYSLOG_TraditionalFileFormat")
include(file="/etc/rsyslog.d/*.conf" mode="optional")
*.* @@localhost:12515
*.info;mail.none;authpriv.none;cron.none /var/log/messages
authpriv.* /var/log/secure
mail.* -/var/log/maillog
cron.* /var/log/cron
*.emerg :omusrmsg:*
uucp,news.crit /var/log/spooler
local7.* /var/log/boot.log
以上配置转发了12525端口的syslog,@@代表udp;
如果此时需要系统日志,则需要以下配置:tail -500f /var/log/messages 则会看到系统日志一直在刷新保存
module(load="imuxsock" SysSock.Use="off")
module(load="imjournal" StateFile="imjournal.state")
module(load="imklog")
module(load="immark")
$imjournalRatelimitInterval 0
如果需要将sprigboot日志同时也存储在messages文件,则需要以下配置:
注意:这里监听12525端口,则在logstash启动时,同时监听12525,会出现端口占用,则logstash不会接收到springboot日志数据;
# 监听 UDP 端口
module(load="imudp")
input(type="imudp" port="12525")
# 监听 TCP 端口
module(load="imtcp")
input(type="imtcp" port="12525")
修改完配置之后,执行 systemctl restart rsyslog 重新启动服务
4、集成logstash
1、拉取logstash镜像
logstash的版本要和ES的版本一致,否则可能出现其他问题
docker pull docker.elastic.co/logstash/logstash:7.4.0
2、配置logstash
除了以下配置,其他的都使用logstash容器中的默认配置,可以起一个空的容器,把这些默认配置(config目录和pipeline目录)复制出来
logstash.yaml:
config.reload.automatic: true
config.reload.interval: 3s
http.host: "0.0.0.0"
path.logs: /usr/share/logstash/logs/
logstash.conf:
status = error
name = LogstashPropertiesConfig
appender.console.type = Console
appender.console.name = plain_console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %m%n
appender.json_console.type = Console
appender.json_console.name = json_console
appender.json_console.layout.type = JSONLayout
appender.json_console.layout.compact = true
appender.json_console.layout.eventEol = true
# Define Rolling File Appender
appender.rolling.type = RollingFile
appender.rolling.name = rolling
appender.rolling.fileName = ${sys:ls.logs}/logstash-plain.log
appender.rolling.filePattern = ${sys:ls.logs}/logstash-%d{yyyy-MM-dd}-%i.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = [%d{ISO8601}][%-5p][%-25c] %m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size = 100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 20
rootLogger.level = ${sys:ls.log.level}
rootLogger.appenderRef.console.ref = ${sys:ls.log.format}_console
rootLogger.appenderRef.rolling.ref = rolling
pipelines.yml: 在pipeline目录中配置几个管道,则在这里对应配置
- pipeline.id: system-syslog
path.config: "/usr/share/logstash/pipeline/fscr-syslog.conf"
fscr-syslog.conf:
input {
syslog {
port => 12525
type => "system-syslog"
}
}
filter {
if [type] == "system-syslog" {
mutate {
# Remove ANSI escape sequences
gsub => [
"message", "\e\[\d+(;\d+)*m", ""
]
}
if [message] =~ /^\[/ {
dissect {
mapping => {
"message" => "[%{timestamp}] - [%{loglevel}] - [%{app}] - [%{thread_info}] - [%{source_class}] - %{log_message}"
}
}
}
mutate {
# Convert "WARN" to "WARNING"
gsub => [
"loglevel", "^WARN$", "WARNING"
]
add_field => [ "received_at", "%{@timestamp}" ]
add_field => [ "received_from", "%{host}" ]
add_field => [ "syslog_hostname", "%{logsource}" ]
add_field => [ "syslog_severity", "%{loglevel}" ]
add_field => [ "syslog_program", "%{app}" ]
add_field => [ "syslog_message", "%{message}" ]
add_field => [ "syslog_timestamp", "%{timestamp}" ]
remove_field => ["severity_label", "facility_label", "facility", "priority"]
}
date {
match => ["adjusted_received_at", "ISO8601"]
timezone => "Asia/Shanghai"
target => "@timestamp"
}
}
}
output {
if [loglevel] == "WARNING" or [loglevel] == "ERROR" {
elasticsearch {
hosts => ["http://esHost:9200"]
index => "logstash-%{+YYYY.MM.dd}"
template_name => "logstash" # 指定模板(该模板已经存在于es中)
template_overwrite => false
}
}
if [loglevel] == "WARNING" or [loglevel] == "ERROR" {
stdout {
codec => rubydebug
}
}
}
logstash.json索引文件:
{
"name": "logstash",

"logstash-*"
],

"refresh_interval": "5s"
}
},

}

}
},
"match_mapping_type": "string",
"match": "*"
}
}
],

},
"longitude": {
"type": "half_float"
}
}
},
"@version": {
"type": "keyword"
}
}
},
"aliases": {}
}
启动容器:
docker run --name logstash -itd --net=host \
-v /opt/fscr/middleware/logstash/logstash/config:/usr/share/logstash/config \
-v /opt/fscr/middleware/logstash/logstash/pipeline:/usr/share/logstash/pipeline \
-p 5044:5044 -p 9600:9600 \
logstash:8.8.0
容器启动后,无error日志,可以看到打印的日志信息,为正常启动;
