PRTG Manual: Notification Delivery

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, leave the respective fields empty.

If you use PRTG on premises and open the system administration page from a different administration page, PRTG asks 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 appears. 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. 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 sends messages.
    For more information, see section Notification Delivery.
  2. Check and set up Notification Contacts for users so that you can define them as recipients of notifications.
    For more information, see section Notification Contacts.
  3. Check and set up Notification Templates to define the notification methods and their content.
    For more information, see section Notification Templates.
    icon-i-round-blueYou 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 are sent.
    For more information, see section Sensor Notification Triggers Settings.

icon-i-round-blueWe 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. 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 a different notification for the corresponding object.

SMTP Delivery

icon-i-round-blueThis documentation refers to an administrator accessing the PRTG web interface on a master node. If you use other user accounts, interfaces, or failover 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.

Description

SMTP Delivery Mechanism

Define how PRTG sends emails using the Simple Mail Transfer Protocol (SMTP):

  • 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 with one as primary and one as fallback server. Enter data below.

icon-i-round-blueIf you monitor the IT infrastructure in your network address translation (NAT) or LAN, using your own LAN-based relay server ensures faster delivery of notification emails.

icon-prtg-on-demandThis option is not available in PRTG hosted by Paessler. PRTG hosted by Paessler uses SendGrid for email notifications. For more information, see the Paessler website: FAQ – PRTG hosted by Paessler.

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 Domain Name System (DNS) name of the PRTG core server system. 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.

Encrypt Connection

This field is only visible if you enable SMTP relay server above. Define the security level for SMTP connections:

  • If supported by the server (default): Use a secure connection (default).
  • Never: Use a connection that is not secure with plain text transfer.

icon-prtg-on-demandThis option is not available in PRTG hosted by Paessler.

Encryption Method

This setting is only visible if you enable SMTP relay server and encryption above. It is only relevant for secure connections. Select the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) version that your SMTP device supports.We recommend that you use the default value. If you do not get a connection, try with a different setting. Choose from:

  • SSL V2 or V3 (default)
  • SSL V3
  • TLS 1.0
  • TLS 1.1
  • TLS 1.2

SMS Delivery

icon-i-round-blueAlthough 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, contact your SMS provider directly.

icon-i-round-blueInstead of using a preconfigured 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 preconfigured options).

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