Monitoreo de servidores Windows y Gnu/Linux y envío de alertas por correo al presentarse saturación de recursos monitoreados utilizando la herramienta Cacti

Abstract

Thomas Information Management Technical Services is a company dedicated to the processing and custody of physical and digital documents for private and government entities. One of the company's clients is the Banco Agrario de Colombia, for which the company developed SIGDOC, a custom software that allows bank officials to review customer documentation for credit studies. The SIGDOC application consists of various services such as databases, reporting, file sharing, proxies, email, applications, among others, which run on servers with operating systems like Windows Server, Linux Centos 6, Linux Centos 7, and Ubuntu. These servers are installed in different data centers that interconnect with the Banco Agrario's private network. It is essential for Thomas Information Management Technical Services to have monitoring systems for these servers that allow it to respond to potential incidents of SIGDOC system unavailability before they occur and affect queries and system performance. Being able to monitor the system allows the entire technology staff to act promptly in the face of any incident. To facilitate the monitoring task of the technology area, the CACTI tool was installed on an Ubuntu server. This tool allows monitoring the status of the servers' technological resources and sending alerts to the technology area staff whenever a saturation occurs on any server using a Zimbra mail server that was also installed on an Ubuntu operating system and parameterized to be interconnected with the monitoring tool. The monitoring tool, together with the alert system, allowed the technology staff to act promptly in the face of any saturation or unavailability incident of the SIGDOC system modules, thus guaranteeing the service level agreements (SLAs) that the company has contracted with the Banco Agrario and improving the quality of service and perception that bank officials have of the SIGDOC information system.
