In the Notification Delivery settings, you can define and test global settings for notification delivery. If you do not want to use a specific notification method, just leave the respective fields empty.

icon-prtg-on-premisesIf you use PRTG on premises and open the system administration page from another administration page, PRTG will ask you to enter your credentials again for security reasons if 15 minutes (900 seconds) have passed since your last credential-based login. A dialog box will appear. Enter your Login Name and Password for PRTG in the corresponding fields and confirm to continue.

Note

This section describes one of four steps to set up the notification system in PRTG. To complete your notification setup, go through all of the following steps:

  1. Check and set up the Notification Delivery settings to define how and to which recipient PRTG will send messages.
    For detailed information, see section System Administration—Notification Delivery.
  2. Check and set up Notification Contacts for PRTG users so that you can define them as recipients of notifications.
    For detailed information, see section Account Settings—Notification Contacts.
  3. Check and set up Notification Templates to define the notification methods and their content.
    For detailed information, see section Account Settings—Notification Templates.
    icon-i-roundYou can also check or edit notification templates via the Notification Triggers tab. For more information, see section Sensor Notification Triggers Settings.
  4. Check and set up Notification Triggers for objects to define when notification messages will be sent.
    For detailed information, see section Sensor Notification Triggers Settings.

icon-i-roundWe recommend that you always set up at least two notifications with different delivery methods for a notification trigger, for example, one email notification and one SMS notification. If delivery via email fails (because of an email server failure or other reasons), PRTG can still notify you via your smartphone. Simply set your latency setting to a state trigger and a notification via a different delivery method than the one for the first trigger. Or set up a second trigger with another notification for the corresponding object.

icon-i-roundThis documentation refers to the PRTG System Administrator user accessing the PRTG web interface on a master node. If you use other user accounts, interfaces, or nodes, you might not see all of the options in the way described here. If you use a cluster installation, note that failover nodes are read-only by default.

SMTP Delivery

SMTP Delivery Mechanism

Define how PRTG sends emails using Simple Mail Transfer Protocol (SMTP). Choose from:

  • Direct delivery using built-in email relay server (default): Use the SMTP relay server built into PRTG. This server manages its own email queue. For each email, it looks up the target SMTP server via the MX record of the target domain, and sends the email.
  • Use SMTP relay server (recommended in LANs/NATs): Set up your own SMTP relay server to send emails. Enter data below.
  • Use two SMTP relay servers (primary and fallback server): Set up two SMTP relay servers—one as primary and one as fallback server. Enter data below.

icon-i-roundIf you monitor the IT infrastructure in your NAT or LAN, using your own LAN-based relay server ensures faster delivery of notification emails.

Sender Email

Enter an email address to use as sender of all emails. This setting is global and applies to all email notifications by default. You can override the sender email in the settings of individual Notifications.

Sender Name

Enter a name to use as sender of all emails. This setting is global and applies to all email notifications by default. You can override the sender name in the settings of individual Notifications.

HELO Ident

Enter the HELO Ident for SMTP. This must be a unique name, preferably the DNS name of the machine running PRTG. See SMTP RFC 2821: The sender-SMTP must ensure that the domain parameter in a HELO command is a valid principal host domain name for the client host.

SMS Delivery

icon-i-roundAlthough PRTG has built-in support for the Application Programming Interface (API) of some SMS providers, we cannot officially provide support regarding these SMS service providers. If you have technical questions about SMS delivery beyond PRTG, please contact your SMS provider directly.

icon-i-roundInstead of using a pre-configured provider, you can always use a custom URL that enables you to use extended parameters (this is also an alternative when using providers for which we offer pre-configured options).

You need an internet connection to send text messages via the HTTP API.
