    2021/07/12 12:09 1/8 5. Zabbix appliance 5. Zabbix appliance As an alternative to setting up manually or reusing existing server for Zabbix, users may download Zabbix appliance. To get started, boot the appliance and point your browser at the IP it has received over DHCP. Booting Zabbix appliance Zabbix appliance versions are based upon the following OpenSUSE versions: Zabbix appliance version OpenSUSE version 2.2.0 12.3 It is available in the following formats: vmdk (VMware/Virtualbox) OVF (Open Virtualisation Format) KVM CD ISO HDD/flash image Preload ISO Xen guest Microsoft VHD Preload USB Zabbix Documentation 2.2 - https://www.zabbix.com/documentation/2.2/ Last update: 2018/09/04 11:39 manual:appliance https://www.zabbix.com/documentation/2.2/manual/appliance It has Zabbix server configured and running on MySQL, as well as frontend available. The appliance has been built using SUSE Studio. 1 Changes to SUSE configuration There are some changed applied to the base OpenSUSE configuration. 1.1 MySQL configuration changes Binary log is disabled; InnoDB is configured to store data for each table in a separate file. 1.2 Using a static IP address By default the appliance uses DHCP to obtain IP address. To specify a static IP address: Log in as root user; Open file /etc/sysconfig/network/ifcfg-eth0 in your favourite editor; Set BOOTPROTO variable to static; Set IPADDR, NETMASK and any other parameters as required for your network; Create file /etc/sysconfig/network/routes. For the default route, use default 192.168.1.1 - - (replacing with your gateway address).

  • The Open-‐Source Monitoring Landscape
    The Open-Source Monitoring Landscape Michael Merideth Sr. Director of IT, VictorOps [email protected], @vo_mike My History and Background • Working in IT since the mid 90’s • Mostly at startups in the Colorado Front Range area • Along for the ride during the “dot com boom” • Build my career using open-source tools Since the 90’s now, there’s been a sharp division in tools and methodology between the enterprise space and the startup and small business communi;es. Obviously, smaller businesses, especially in the tech sector, were early and eager adopters of open- source technology, and much quicker to learn to rely on open-source tool chains in business-cri;cal applica;ons. Up at the enterprise level, at the public companies, they’re only now fully-embracing Linux as a business-cri;cal tool, and I think that’s largely because “the enterprise” is star;ng to be defined by companies that either came up in the dot com era, like Google, or built the dot com era, like Sun, or Dell, or let’s say RedHat. So, the “enterprise” had their toolchain, built on commercial solu;ons like HPUX and OpenView and so on, and the startup community, the “dot com” community had a completely different toolchain, based on Linux, based on open standards and protocols, built with open-source components like GNU, and Apache, and ISC Bind and so on. I’m lucky enough that I’ve been able to spend my career in the startup sphere, working with that open-source toolchain. I started working in IT in the mid 90’s in the Colorado front range, and I’ve spent my ;me since then working for and consul;ng at early-stage startups and other “non enterprise” shops.

  • Zabbix Agent
    Installation of Zabbix server for Ubuntu 16.04 and ubuntu 16.10 Zabbix server : Zabbix is an Open Source, high-level enterprise software designed to monitor and keep track of networks, servers and applications in real time. Build in a server-client model, Zabbix can collect different type of data than are used to create historical graphics and output performance or load trends of the monitored targets. The server has the ability to check standard networking services (HTTP, FTP, SMTP, IMAP etc) without the need to install extra software on the monitored hosts. However, in order to gather data and create statistics about local services or other specific system resources that run on remote instances, such as CPU, disks, internal system process, RAM, etc, you need to install and configure a Zabbix agent. 1. Install a LAMP stack : Zabbix will need web server, a data base and PHP in order to correctly function,setting up a LAMP stack (linux, Apache,MySQL,and PHP) fulfills all of these requirements. sudo apt-get install lamp-server^ 2. Adding Apt Repository Before installing Zabbix first configure zabbixzone rpm repository in our system using following commands. Latest version of Zabbix 3.2 a. wget http://repo.zabbix.com/zabbix/3.2/ubuntu/pool/main/z/zabbix- release/zabbix-release_3.2-1+xenial_all.deb b. sudo dpkg -i zabbix-release_3.2-1+xenial_all.deb c. sudo apt-get update 3.

Locci*, F. Ehm, L. Gallerani, J. Lauener, J. Palluel, R. Voirin CERN, Geneva, Switzerland Abstract The CERN accelerator controls infrastructure spans sev- eral thousands of computers and devices used for Acceler- ator control and data acquisition. In 2009, a fully in-house, CERN-specific solution was developed (DIAMON) to monitor and diagnose the complete controls infrastructure. The adoption of the solution by a large community of users, followed by its rapid expansion, led to a final product that became increasingly difficult to operate and maintain. This was predominantly due to the multiplicity and redundancy of services, centralized management of data acquisition and visualization software, its complex configuration and its intrinsic scalability limits. At the end of 2017, a com- pletely new monitoring system for the beam controls infra- structure was launched. The new "COSMOS" system was developed with two main objectives in mind: firstly, de- tecting instabilities and preventing breakdowns of the con- trol system infrastructure. Secondly, providing users with Figure 1: Main types of control system hosts. a more coherent and efficient solution for development of their specific data monitoring agents and related dash- OBJECTIVES AND SCOPE boards. This paper describes the overall architecture of Reviewing the existing system and evaluating major COSMOS, focusing on the conceptual and technological products in the monitoring field (collectd, Icinga2, Zabbix, choices for the system.
