Introduction to Zabbix - Company, Product, Services and Use CasesZabbix
About Zabbix Software:
Zabbix is an enterprise-class open source distributed monitoring solution designed to monitor and track performance and availability of network servers, devices, services and other IT resources.
Zabbix is an all-in-one monitoring solution that allows users to collect, store, manage and analyze information received from IT infrastructure, as well as display on-screen, and alert by e-mail, SMS or Jabber when thresholds are reached.
Zabbix allows administrators to recognize server and device problems within a short period of time and therefore reduces the system downtime and risk of system failure. The monitoring solution is being actively used by SMBs and large enterprises across all industries and almost in every country of the world.
In this session, we’ll review how previous efforts, including Netfilter, Berkley Packet Filter (BPF), Open vSwitch (OVS), and TC, approached the problem of extensibility. We’ll show you an open source solution available within the Red Hat Enterprise Linux kernel, where extending and merging some of the existing concepts leads to an extensible framework that satisfies the networking needs of datacenter and cloud virtualization.
In this talk, Vladi looks at the new Volume encryption option (due in CloudStack 4.18). He presents the new ability to use encrypted root and data volumes on different storage types, the benefits and the current limitations of the implementation.
Vladimir Petrov is a QA engineer with more than 20 years of experience in the IT field. He is using and testing Apache CloudStack for almost 3 years now. Currently working as a QA Engineer in ShapeBlue.

CloudStack Collaboration Conference 2022 took place on 14th-16th November in Sofia, Bulgaria and virtually. The day saw a hybrid get-together of the global CloudStack community hosting 370 attendees. The event hosted 43 sessions from leading CloudStack experts, users and skilful engineers from the open-source world, which included: technical talks, user stories, new features and integrations presentations and more.
OVN (Open Virtual Network) を用いる事により、OVS (Open vSwitch)が動作する複数のサーバー（Hypervisor/Chassis）を横断する仮想ネットワークを構築する事ができます。
本スライドはOVNを用いた論理ネットワークの構成と設定サンプルのメモとなります。
Using OVN, you can build logical network among multiple servers (Hypervisor/Chassis) running OVS (Open vSwitch).
This slide is describes HOW TO example of OVN configuration to create 2 logical switch connecting 4 VMs running on 2 chassis.
This presentation features a walk through the Linux kernel networking stack covering the essentials and recent developments a developer needs to know. Our starting point is the network card driver as it feeds a packet into the stack. We will follow the packet as it traverses through various subsystems such as packet filtering, routing, protocol stacks, and the socket layer. We will pause here and there to look into concepts such as segmentation offloading, TCP small queues, and low latency polling. We will cover APIs exposed by the kernel that go beyond use of write()/read() on sockets and will look into how they are implemented on the kernel side.
