Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML and run client-side by a JavaScript engine in the user's web browser. Node.js lets developers use JavaScript for server-side scripting—running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "<a href="https://www.hackthesec.co.in/search/label/Java">JavaScript </a>everywhere" paradigm, unifying web application development around a single programming language, rather than different languages for server side and client side scripts.now install the nodejs using following command line.</span></span><br />

<span style="color: #0b5394; font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b><u>Zabbix Email-Notification Setting</u></b></span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;"><b>E-mail settings</b></span></span><br />
<span style="font-family: verdana, geneva, sans-serif;"><span style="font-size: 15px; line-height: 26px;">Initially there are several predefined notification <b>delivery methods</b> in Zabbix. <b>E-mail</b> is one of those.</span></span><br />
<br />
<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 />
