下面将匹配 nginx access.log 和 error.log ，mysql 5.6的慢日志，php 的error.log 以及 php-fpm.log
1、/data/nginx/logs/access_log
access 日志
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
写入测试日志
echo '203.195.212.249 - - [20/Apr/2015:14:37:34 +0800] "GET /v1/coupon/get?access_token=c7e47389ddbe4113a2034798fa5f2084&card_code=http://betawsh.szsllt.com/vikduo/Cards/cancel/784&shop_user_id=103&sign_method=1×tamp=150420144004&sign=96A22ED636A178C1C71291AD7C0C1A0A HTTP/1.0" 200 41 "-" "-" "218.18.0.142"' >> nginx_test_access.log
匹配规则如下：
["message","%{IPORHOST:host_ip} - %{USERNAME:remote_user} \[%{HTTPDATE:time_local}\] \"%{WORD:method} %{URIPATHPARAM:request} %{WORD:procotol}/%{NUMBER:http_version}\" %{INT:status} %{INT:body_bytes_sent} %{QS:http_referer} %{QS:http_user_agent} %{QS:http_x_forwarded_for}"]
参考：http://blog.arganzheng.me/posts/use-logstash-to-collect-nginx-access-log.html
另：如果log_format 是完整的
log_format main '$server_name $remote_addr - $remote_user [$time_local] "$request" '
'$status $upstream_status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for" '
'$ssl_protocol $ssl_cipher $upstream_addr $request_time $upstream_response_time';
测试日志格式：

匹配规则如下：
# /data/logstash/bin/etc/patterns文件中，自定义的 MYTIME
# HOSTPORT %{IPORHOST}:%{POSINT}
filter{
grok{
patterns_dir => "/data/logstash/bin/etc/patterns"
match => [ "message", "(%{IPORHOST:server_name}|-) (%{IPORHOST:remote_addr}|-) - (%{USERNAME:remote_user}|-) \[%{HTTPDATE:time_local}\] \"%{WORD:method} %{URIPATHPARAM:request} %{WORD:procotol}/%{NUMBER:http_version}\" %{INT:status} %{INT:body_bytes_sent} %{QS:http_referer} %{QS:http_user_agent} %{QS:http_x_forwarded_for} %{USERNAME:ssl_procotol}? %{USERNAME:ssl_cipher}?

}
}
2、nginx error.log
/data/nginx/logs/nginx_test_access.log
有两种格式， notice的规则与 warn、error 的不一样
2016/07/13 15:32:38 [notice] 1285#0: signal 17 (SIGCHLD) received
2016/07/13 13:40:17 [warn] 1288#0: *110535 an upstream response is buffered to a temporary file /data/nginx/fastcgi_temp/3/01/0000000013 while reading upstream, client: 10.100.100.35, server: 10.100.200.19, request: "GET /log.php?auth=-curl HTTP/1.0", upstream: "fastcgi://127.0.0.1:9000", host: "posapitest.vikduo.com", referrer: "blank"

匹配规则如下：
filter{
grok {
match => { "message" => "(?%{YEAR}[./]%{MONTHNUM}[./]%{MONTHDAY} %{TIME}) \[%{LOGLEVEL:severity}\]" }
}
if [severity] == 'notice' {
grok {
match => { "message" => "(?%{YEAR}[./-]%{MONTHNUM}[./-]%{MONTHDAY}[- ]%{TIME}) \[%{LOGLEVEL:severity}\] %{POSINT:pid}#%{NUMBER}: %{GREEDYDATA:errormessage}(?:, client: (?%{IP}|%{HOSTNAME}))?(?:, server: %{IPORHOST:server})?(?:, request: %{QS:request})?(?:, upstream: \"%{URI:upstream}\")?(?:, host: %{QS:host})?(?:, referrer: \"%{URI:referrer}\")?" }
}
}else{
grok {

}
}
}
3、mysql slow_query.log

SET timestamp=1467014886;
SELECT * FROM `wx_user_infos`
LIMIT 3645250, 25;
或者：

SET timestamp=1467265916;
UPDATE `wx_infos` SET `modified`=1467265915 WHERE `id`=14687666;
匹配规则如下：
