Smokeping, programado en perl, es un monitor de latencias basado en RRDTool (del mismísimo autor), mide el retardo de ICMP y varios servicios (DNS, SSH, HTTP, SMTP, LDAP, etc). En esta entrada, mostraremos como instalar desde el código fuente Smokeping, como integrarlo en el servidor web Nginx y configurarlo básicamente en CentOS 6.4

• Smokeping Webpage: http://oss.oetiker.ch/smokeping/
• Webserver: Nginx 1.5.11
• Smokeping: 2.6.9
• Centos: 6.4

Agregamos el repositorio creando el fichero /etc/yum.repos.d/nginx.repo

[nginx]

yum install nginx

Hacemos un backup de la configuración predeterminada actual.

mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf_backup
