Hello everyone! As part of my coursework, I researched the capabilities of a domestic cloud platform, Yandex.Cloud. The platform offers various services to address practical tasks. However, sometimes it is necessary to configure your cloud application with a sufficiently complex infrastructure based on these services. In this article, I want to share my experience in deploying such an application. What do I want to achieve? Grafana — […]

While developing a solution for a client, two tasks arose that I wanted to solve elegantly using Zabbix's standard functionality. Task 1: Monitoring the current firmware version on Mikrotik routers. This task is easily accomplished by adding an HTTP agent to the template. The agent retrieves the current version from the Mikrotik website, while a trigger compares the current version with the actual one and issues an alert if there's a discrepancy. When […]
According to statistics, the volume of network traffic increases by about 50% each year. This leads to an increase in the load on equipment and, in particular, raises the performance requirements for IDS/IPS. You can purchase expensive specialized hardware, but there’s a cheaper option — implementing one of the open-source systems. Many beginner administrators believe that installing and configuring a free IPS […]
