Windows Server

Criando Web Site com alta disponibilidade Azure CLI (Bash)

Neste artigo iremos criar Web Site em alta disponibilidade, composto por duas VM Windows Server 2019 com IIS habilitado e um load balance, não iremos abordar aqui segurança como Application Gateway, WAF, API MAN, etc. Este artigo visa somente a criação via scritp de toda a infraestrutura (também não iremos abordar o deploy de qualquer aplicação neste artigo).

Add Perfom Monitor IIS Zabbix

Cenário:

1-) Servidor Windows Server 2012 R2 IIS 8.5

2-) Dois site públicos rodando dentro do IIS

3-) Zabbix monitorando

Eu precisa monitorar as conexões para o IIS, até ai temos o seguinte contador do Windows “perf_counter[\Web Service(_Total)\Current Connections]” este contador mostra as conexões correntes do IIS todo, ou seja todos os sites, eu precisava verificar as conexões de cada site, ai vem o pulo do gato.

No contato “perf_counter[\Web Service(_Total)\Current Connections]” substituímos o (_Total) pelo nome do site, neste exemplo (Intranet_corp) o nosso contador ficará desta forma “perf_counter[\Web Service(intranet_corp)\Current Connections]”.

Mas quando os agent do zabbix enviar as informações ele fará o envio do IIS todo o (_Total), agora vamos a configuração para o envio correto das informações.

No arquivo .conf do zabbix temos que fazer as seguinte alterações:

===============================================================================================
LogFile=c:\zabbix\log\zabbix_agentd.log
Server=xxx.xxxx.xxx.xxx
ServerActive=xxx.xxxx.xxxx.xxx
Hostname=SRV-WEB-SP-001

Alias = intranet_corp[anon]:perf_counter[\Web Service(_Total)\Current Connections]
===============================================================================================

Salve o arquivo, agora no item do template pode deixar desta forma:

“perf_counter[\Web Service(intranet_corp)\Current Connections]”

Pronta agora irá conseguir ver as conexões para este site, para cada site devemos adiciona-lo no .config do zabbix e um item no template no IIS.

Seja Feliz!!!!
