How to Install and Configure cAdvisor for Container Monitoring on RHEL 7 cAdvisor (Container Advisor) is an open-source agent developed by Google that collects, aggregates, processes, and exports resource usage and performance metrics for running containers. It provides a real-time web UI and a Prometheus-compatible metrics endpoint, making it the standard solution for container observability […]
Introduction How to Configure cAdvisor Container Metrics on FreeBSD 15 is a core administration task for any FreeBSD 15 server operator. FreeBSD 15 ships with the 15.0-RELEASE kernel, ZFS as the default root filesystem, Capsicum capability sandboxing improvements, and an updated ports tree. Unlike Linux distributions, FreeBSD uses rc(8) for service management, pf for packet […]
How to Build Grafana Dashboards for Linux Server Metrics on RHEL 7 Grafana is the de facto standard for visualising time-series data collected by Prometheus, InfluxDB, Graphite, and dozens of other data sources. A well-constructed Grafana dashboard can surface CPU saturation, memory pressure, disk I/O bottlenecks, and network anomalies at a glance, dramatically reducing the […]

Introduction Deploying configure blackbox exporter on a FreeBSD 15 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard base + ports approach […]
How to Configure SNMP Monitoring on RHEL 7 Simple Network Management Protocol (SNMP) is one of the most widely supported protocols for monitoring network devices, servers, storage appliances, and virtually any managed infrastructure component. Configuring SNMP on Red Hat Enterprise Linux 7 allows your monitoring platform — whether Zabbix, LibreNMS, Nagios, or Prometheus with the […]
Introduction This guide explains how to Configure OpenTelemetry Collector on FreeBSD 15 on FreeBSD 15. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained privilege […]
Introduction FreeBSD 15 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up install graylog log management on FreeBSD 15 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any Linux distribution. This guide […]
Introduction Deploying set up the elastic stack elk on a FreeBSD 15 machine differs from Linux in several important ways: packages come from the FreeBSD Ports Collection or the binary pkg repository, services are registered in /etc/rc.conf via sysrc(8), and firewall rules are written in pf.conf(5) syntax. This tutorial stays entirely within the standard base […]
