  • How to install collectd and send metrics to Graphite/Statsd

    Collectd is a daemon which collects system and application performance metrics periodically and provides mechanisms to store the values in a variety of ways, in our case sending to Graphite. Collectd gathers metrics from various sources, e.g. the operating system, applications, log files and external devices, and stores this information or makes it available over the network. Those statistics can be used to monitor systems, find performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you’re at the right place, too.

    Grafana Loki is an open source log aggregation tool provided by the Grafana Labs. It is a horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream.

    Promtail is Loki’s log collector, which sends log tags to Grafana Loki for indexing.

  • How to Setup Central Logging Server with Rsyslog in Ubuntu 20.04 – Citizix

    Rsyslog is an open-source software utility used on UNIX and Unix-like computer systems for forwarding log messages in an IP network. It is an open-source utility for log processing. It permits the logging of data from different types of systems in a central repository. Rsyslog is a Syslog protocol with more extensions, features, and benefits.

    Rsyslog can deliver over one million messages per second to local destinations when limited processing is applied making it so powerful. By default, Linux uses the syslog daemon to record logs about how the system is running and then putting these logs into a central repository in: /var/log where we can examine and investigate them.
    In simple terms of meaning everything from kernel events to user actions is logged by Linux, allowing you to see al most any action performed on your pc or servers.

  • 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.
