  • Use dmseg to check your Linux system's kernel message buffer | Network World

    The dmesg command displays the content of the kernel's message buffer since the system's most recent boot. It displays a lot of details on how the system is working and problems it might be running into that you won't normally see. That can be a lot of data, but there are several tricks for paring it down.

    For example, Even though the system queried below has only been up a little more than three days, it's collected more than a thousand lines of data.

  • Working with gnome-boxes - Unixcop the Unix / Linux the admins deams

    In my PC I’ve worked with Virtual box for years. Then virtual box, for some reason, was removed from the Debian repository. As I wasn’t using those VMs for something critical I’ve just didn’t bother to find out why or to search some alternate repo. Few months ago I need some virtual machines on my PC, so I began working with gnome-boxes.

  • How To Install Terminalizer on Ubuntu 20.04 LTS - idroot

    In this tutorial, we will show you how to install Terminalizer on Ubuntu 20.04 LTS. For those of you who didn’t know, Terminalizer is a very useful terminal recording tool designed for different distributions of the Linux operating system. Terminalizer works in the same way as a desktop screen recorder but instead runs in your terminal.

  • How to Install Telegraf Configure InfluxDB2 output in Debian 11

    In this guide we are going to learn how to install Telegraf and configure InfluxDB v2 output on a Debian 11.

    Telegraf is a plugin-driven server agent for collecting & reporting metrics, and is the first piece of the TICK stack. Telegraf has plugins to source a variety of metrics directly from the system it’s running on, pull metrics from third-party APIs, or even listen for metrics via a statsd and Kafka consumer services. It also has output plugins to send metrics to a variety of other datastores, services, and message queues, including InfluxDB, Graphite, OpenTSDB, Datadog, Librato, Kafka, MQTT, NSQ, and many others.

  • How to Install and Configure InfluxDB2 in Debian 11

    InfluxDB is the database in which we will store the metrics sent from the agent. This database is designed to withstand high write and read loads.

    InfluxDB is an open source time series database. It has everything you need from a time series platform in a single binary – a multi-tenanted time series database, UI and dashboarding tools, background processing and monitoring agent. All this makes deployment and setup a breeze and easier to secure.

    The InfluxDB Platform also includes APIs, tools, and an ecosystem that includes 10 client and server libraries, Telegraf plugins, visualization integrations with Grafana, Google Data Studio, and data sources integrations with Google Bigtable, BigQuery, and more.

  • How to Install and Use Ping Command in Linux

    PING is undoubtedly a millennial word. It’s rooted in quotidian life and henceforth has become a concept to be unveiled. Many of us might be known of the fact that the word ‘ping‘ is not actually a word but an acronym. PING stands for Packet Internet Groper. The meaning
    says it all.

  • How to use monitoring to troubleshoot Ansible Automation Platform | Enable Sysadmin

    Running an Ansible automation controller in OpenShift provides an easy way to scale an Ansible automation controller. However, as with any virtualization platform, you need to enable the Ansible automation controller to run as efficiently as possible.

    Often, OpenShift runs on top of another virtualization platform, and understanding how resources are used at the various virtualization levels is essential. Overcommitting CPU and memory resources in your virtualization platform can impact OpenShift performance. Therefore, it is important to have a 1:1 commit ratio for CPU and memory in your virtualization platform and let OpenShift manage resource overcommitment. In addition to looking at CPU and memory overcommitment, you need to understand what other pods are running on the OpenShift instances in order to prevent resource conflicts.

    Proper management of OpenShift guarantees the availability of the Ansible automation controller and other applications running in the OpenShift environment. Quotas on namespaces set the maximum amount of CPU and memory resources a project can consume, limiting the impact one project can have on other projects. In addition, the request and limit settings for the task container set the CPU and memory resources the Ansible automation controller has for running jobs.

    By default, the Ansible automation controller installer sets the CPU request to 1,500 millicores and the memory request to 2GBs. You can use the task_cpu_request and task_mem_request variables to set request sizes for the task container in the Ansible automation controller installer inventory. These settings directly impact the number of forks an Ansible automation controller instance has available for running jobs.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
