You can send alerts to users via email (SMTP) or pager (SNPP). Many operating systems include an SMTP server (such as Sendmail or Postfix) with their distributions. If your operating system does not include a mail server, you must install one or specify a separate SMTP server in the system settings. Many pagers can accept messages via email, but Resource Manager also provides the option of sending pages via SNPP if you specify an SNPP server in settings.
Follow these steps to edit SMTP and SNPP settings.
You must be logged in to a user account with management privileges.
From the Navigation menu, select Advanced.
The Settings page appears.
Change the following SMTP settings as needed:
Table 14.1. SMTP Options
Field Description SMTP Host Set to the value of your corporate email server. SMTP Port Specify the port number (usually port 25). SMTP Username Enter a value if your mail server requires authentication; otherwise, leave this blank. SMTP Password Enter a value if your mail server requires authentication; otherwise, leave this blank. From Address for Email Enter a value if you want email to come from a specific email address. Use TLS? Select this option if you use transport layer security for your email alerts.
If you want to send pages, enter a value in the Page Command field. The pageCommand variable enables the system to execute pageCommand when a page is sent, and writes the message to the standard input of the subshell. The command prints any error messages to standard output. This enables a wider ranging of paging customization.
The standard page command is:
$ZENHOME/bin/zensnpp localhost 444 $RECIPIENT
This uses ZENHOME to send the page from the localhost; however, you can use any page command customizations you prefer. In this case $RECIPIENT is the paging address for the user, as set in the settings for each user.
