實(shí)時(shí)讀取logstash日志，有異常錯(cuò)誤keywork即觸發(fā)報(bào)警。

補(bǔ)充知識(shí)：logstash 調(diào)用exec

我就廢話不多說(shuō)了，還是直接看代碼吧！

[elk@Vsftp logstash]$ cat t3.conf input { stdin { } } filter { grok { match => [ 'message','(?m)s*%{TIMESTAMP_ISO8601:time}s*(?<Level>(S+)).*'] } date { match => ['time', 'yyyy-MM-dd HH:mm:ss,SSS'] } mutate { add_field =>['type','tailong'] add_field =>['messager','%{type}-%{message}'] remove_field =>['message'] }} output { if ([Level] == 'ERROR' or [messager] =~ 'Exception' ) and [messager] !~ '溫金服務(wù)未連接' and [messager] !~ '調(diào)用溫金代理系統(tǒng)接口錯(cuò)誤' and [messager] !~ 'BusinessException' { exec { command => '/bin/smail.pl '%{messager}' '%{type}' ' } } stdout { codec =>rubydebug } } Vsftp:/root# cat /bin/smail.pl #!/usr/bin/perl use Net::SMTP;use HTTP::Date qw(time2iso str2time time2iso time2isoz); use Data::Dumper;use Getopt::Std;use vars qw($opt_d );getopts(’d:’);# mail_user should be your_mail@163.com $message= '@ARGV'; $env='$opt_d'; sub send_mail{ my $CurrTime = time2iso(time()); my $to_address = shift; my $mail_user = ’zhao.yangjian@163.com’; my $mail_pwd = ’xx’; my $mail_server = ’smtp.163.com’; my $from = 'From: $mail_usern'; my $subject = 'Subject: zjcap infon'; my $info = '$CurrTime--$message'; my $message = <<CONTENT; $infoCONTENT my $smtp = Net::SMTP->new($mail_server); $smtp->auth($mail_user, $mail_pwd) || die 'Auth Error! $!'; $smtp->mail($mail_user); $smtp->to($to_address); $smtp->data(); # begin the data $smtp->datasend($from); # set user $smtp->datasend($subject); # set subject $smtp->datasend('nn'); $smtp->datasend('$messagen'); # set content $smtp->dataend(); $smtp->quit();}; send_mail (’zhao.yangjian@163.com’); 2017-01-12 10:19:19,888 jjjjj Exception{ '@version' => '1', '@timestamp' => '2017-01-12T02:19:19.888Z', 'host' => 'Vsftp', 'time' => '2017-01-12 10:19:19,888', 'Level' => 'jjjjj', 'type' => 'tailong', 'messager' => 'tailong-2017-01-12 10:19:19,888 jjjjj Exception'}

以上這篇python實(shí)時(shí)監(jiān)控logstash日志代碼就是小編分享給大家的全部?jī)?nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
