Analisando log Squid do Mikrotik no SARG

O problema do SARG não analisar os logs do Mikrotik é que os logs estão em formatos diferentes, o Mikrotik envia informações ao qual o SARG não entende, gerando uma confusão neste e resultando em não processamento das informações. Para esta integração serão necessários três softwares básicos: SARG, THE Dude e MK2SARG (software que desenvolvi).

Introdução



Depois de muito estudo, consegui fazer a integração do SARG com Mikrotik para análise dos logs de acesso dos clientes. O problema do SARG não analisar os logs do Mikrotik é que os logs estão em formatos diferentes, o Mikrotik envia informações ao qual o SARG não entende, gerando uma confusão neste, e resultando em não processamento das informações.

A solução que encontrei foi desenvolver um aplicativo que converte o arquivo de log no formato correto para análise.

Para esta integração serão necessários três softwares básicos: SARG, THE Dude, MK2SARG (software que desenvolvi).

SARG

Vou começar falando do SARG, uma ferramenta brazuca extremamente útil para análise de log de acesso de usuários. O arquivo principal é o sarg.conf, localizado na pasta sarg/etc. Este arquivo e necessário para o funcionamento do programa. Apesar de ser nacional, o arquivo de configuração está em inglês, deu um pouco de trabalho mas traduzi. Ele é bem intuitivo, as opções estão todas comentadas.

ARQUIVO: /sarg/etc/sarg.conf

Olá pessoal,

Parabens Deliam pelo excelente artigo.

Conforme o tutorial conseguir configurar a Dude para receber os logs do Mikrotik em tempo real, porém o programa mk2sargv2.exe de sua autoria que converte os logs, processa as linhas do syslog gerado pelo dude mas não gera o arquivo access.log para o sarg processar. Também não apresenta nenhuma mensagem de erro. Gostaria de sua ajuda.

Este programa que desenvolveu ele fazer a conversão automatica ? Assim poderia deixar todo processo mesmo no windows todo automatico :D

Talvez vc deva estar usando a versao 3 do MIKROTIK ROUTER OS. Os logs da versao 3, totalmente diferente, por isso n tem compatibilidade com meu programa. Para a versao 3, tenho que escrever 1 novo programa, ok? Pretendo fazer 1 programa novo, assim que tiver pronto, vou postar por aqui. Ate mais.

Bom dia !!
Deliam, primeiramente gostaria de parabenizá-lo pelo excelente tutorial.
E agradecer pois consegui utilizar seu programa para gerar os relatórios de acesso.
Estou testando o uso do mikrotik em minha rede, e um dos "problemas" era a falta de relatórios. Pois temos a necessidade de controlar o acesso dos colaboradores.

Obrigado mais uma vez.

Abraço.

[8] Comentário enviado por Fabio F em 07/05/2009 - 10:39h

Só uma dúvida,
Tem como eu gerar o arquivo de log na hora que eu quizer ??
Esse processo feito pelo seu programa tem que ser manual ?

Abraço.
