<span style="color: #333333; font-family: "verdana" , "geneva" , sans-serif;"><span style="font-size: 15px; line-height: 26px;">Icinga is an open source computer system and network monitoring application. It was originally created as a fork of the Nagios system monitoring application in 2009.</span></span><br />

<span style="color: #333333; font-family: "verdana" , "geneva" , sans-serif;"><span style="font-size: 15px; line-height: 26px;">Icinga is attempting to get past perceived short-comings in Nagios' development process, as well as adding new features such as a modern Web 2.0 style user interface, additional database connectors (for MySQL, Oracle, and PostgreSQL), and a REST API that lets administrators integrate numerous extensions without complicated modification of the Icinga core.</span></span><br />

<div>
<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">There are several benefits of using a transparent proxy. First of all, for end users, a transparent proxy can enhance their web browsing performance by caching frequently accessed web content, while introducing minimal configuration overhead for them. For administrators, it can be used to enforce various administrative policies such as content/URL/IP filtering, rate limiting, etc.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">A proxy server acts as an intermediary between a client and a destination server. The client sends requests to the proxy server which then evaluates the requests and takes necessary actions. In this tutorial, we will be setting up a web proxy server using Squid, which is a robust, customizable and stable proxy server. Personally, I had administered a Squid server with 400+ client workstations for about a year. Although I had to restart the service about once a month in average, CPU and storage utilization, throughput and client response time were all great.</span></span></div>

On the client side it requires only a PXE-capable network interface controller (NIC), and uses a small set of industry-standard network protocols such as DHCP and TFTP.</span></span></div>

<span style="color: #333333; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">The concept behind the PXE originated in the early days of protocols like BOOTP/DHCP/TFTP, and as of 2015 it forms part of the Unified Extensible Firmware Interface (UEFI) standard. Given fast and reliable local area networks (LANs), PXE is the most frequent choice for operating system booting, installation and deployment.</span></span></div>

<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">To configure e-mail settings, go to <b>Administration → Media types</b> and click on <b>Email </b>in the list of pre-defined media types.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/media_types.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/media_types.png" /></a></div>
<span style="color: #0b5394; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b><u><br /></u></b></span></span>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">This will present us with the e-mail settings definition form.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/media_type_email.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/media_type_email.png" /></a></div>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Set the values of SMTP server, SMTP helo and SMTP e-mail to the appropriate for your environment.<b>Press Update when ready.</b></span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Now you have configured 'Email' as a working media type. A media type must be linked to users by defining specific delivery addresses (like we did when configuring a new user), otherwise it will not be used.</span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b>New action</b></span></span><br />
<br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Delivering notifications is one of the things actions do in Zabbix. Therefore, to set up a notification, go to <b>Configuration → Actions</b> and click on Create action.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/new_action.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/new_action.png" /></a></div>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">In this form, enter a name for the action.</span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">{TRIGGER.STATUS} and {TRIGGER.NAME} macros (or variables), visible in the Default subject and Default message fields, will be replaced with the actual trigger status and trigger name values.</span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">In the most simple case, if we do not add any more specific conditions, the action will be taken upon any trigger change from 'Ok' to 'Problem'.</span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">We still should define what the action should do - and that is done in the Operations tab. Click on New in there, which opens a new operation form.</span></span><br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/new_operation.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="https://www.zabbix.com/documentation/3.0/_media/manual/quickstart/new_operation.png" /></a></div>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Here, click on Add in the Send to Users block and select the user ('user') we have defined. Select 'Email' as the value of Send only to. When done with this, click on Add in the operation detail block.</span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><br /></span></span>
<br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">That is all for a simple action configuration, so click Add in the action form.</span></span><br />
