1 ELK 是一个实时分布式的日志分析平台
ELK 是一整套的解决方案
（E）lasticsearch -- 数据库
（L）ogstash -- 收集日志、标准化的程序
（K）ibana -- 图形的展示工具
2 数据批量导入
-X 导入使用的方法 POST
--data-binary 导入数据的格式
@urfile 导入数据的文件名
_bulk 导入关键字
curl -X "POST" "http://192.168.1.13:9200/_bulk" --data-binary @shakespeare.json
如果没有 index 和 type ，我们需要自己指定一下 index 和 type
curl -X "POST" "http://192.168.1.13:9200/haha/xixi/_bulk" --data-binary @accounts.json
3 批量查询数据
查询一条数据
curl -X "GET" "http://192.168.1.12:9200/haha/xixi/1"
查询多条数据，使用 _mget
curl -XGET ‘http://192.168.1.11:9200/_mget?pretty‘ -d ‘{
"docs":[
{
"_index": "haha",
"_type:": "xixi",
"_id": 1
},
{
"_index": "haha",
"_type:": "xixi",
"_id": 2
},
{
"_index": "shakespeare",
"_type:": "act",
"_id": 91400
}
]
}‘
logstash 的安装
安装依赖包 openjdk
yum install java-1.8.0-openjdk -y
yum install logstash-2.3.4-1.noarch.rpm -y
ELK 工作结构模型
+-----------------logstash-------------------++--------+ | +--------+ +---------+ +-----------+ | +---------+ +----------+
| 数据源 | --->| INPUT | -->| FILTER | --> | OUTPUT | ---> | ES 集群 | -->| KIBANA |
+--------+ | +--------+ +---------+ +-----------+ | +---------+ +----------+
+----------------------------------------------+
logstash.conf 初始配置
input{
stdin{}
}
filter{
}
output{
stdout{}
}
插件文档的位置
https://github.com/logstash-plugins
codec 插件
stdout{ codec => "rubydebug" }
file 插件
file{
sincedb_path => "/var/lib/logstash/since.db"
start_position => "beginning"
path => ["/var/tmp/a.log", "/tmp/b.log"]
type => "filelog"
}
python 客户端，发送 tcp 数据
import socket
def tcpmsg(msg):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, socket.IPPROTO_TCP)
s.connect(("192.168.1.10", 8888))
s.sendall(msg+‘\n‘)
s.close()
def udpmsg(msg):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
s.sendto(msg+‘\n‘, ("192.168.1.10", 9999))
syslog 的配置
logstash.conf 配置
syslog{
host => "192.168.1.10"
port => 514
type => "syslog"
}
写 syslog 日志的命令
logger -p local0.info -t mylog "hello world"
配置 /etc/rsyslog.conf
local0.info @192.168.1.10:514
authpriv.info @@192.168.1.10:514
正则宏路径
/opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-patterns-core-2.0.5/patterns/grok-patterns
filter 配置，解析标准 apache 日志 grok{
match => ["message","%{COMBINEDAPACHELOG}"]
}
output 配置写入 ES 集群
if [type] == "filelog"{
elasticsearch {
hosts => ["192.168.1.14:9200"]
index => "weblog"
flush_size => 2000
idle_flush_time => 10
}}
完整的 logstash.conf 配置
input{
file{
sincedb_path => "/var/lib/logstash/since.db"
start_position => "beginning"
path => ["/var/tmp/a.log"]
type => "filelog"
codec => "json"
}
}
filter{
}
output{
if [type] == "filelog"{
elasticsearch {
hosts => ["192.168.1.14:9200"]
index => "weblog"
flush_size => 2000
idle_flush_time => 10
}}
}
