<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> 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.

i_podIf 15 minutes (900) seconds have passed since your last credential-based login and you open a system administration page from a different system administration page, PRTG asks you to enter your credentials again for security reasons. A dialog box appears. Enter your Login Name and Password and click OK to continue.

Note

You have to take the following four steps to set up and use notifications:

  1. Check and set up the notification delivery settings if you use PRTG on premises. These settings define how PRTG sends messages.
  2. Check and set up notification contacts for the user accounts. These contacts define the recipients to which PRTG sends notifications.
  3. Check and set up several notification templates. These templates define the notification methods and their content.
    i_round_blueYou can also check or edit notification templates via the Notification Triggers tab. For more information, see section Notification Triggers Settings.
  4. Check and set up notification triggers settings for objects. These triggers define when PRTG sends notifications.

i_round_blueUsually, there are three successive attempts to deliver a notification. If all of these attempts fail, the notification is lost. To never miss a notification, we recommend that you always set up at least two notifications with different notification methods for a notification trigger, for example, one email notification and one SMS notification. If delivery via email fails, PRTG can still notify you via smartphone as a fallback. For example, use the latency setting of a state trigger to choose a notification with a different notification method than in the first trigger condition, or set up a second trigger with a different notification method for the corresponding object.

i_square_cyanSee sections Notifications Based on Sensor Limits Step by Step and Notifications Based on Libraries Step by Step for step-by-step guides that describe potential notification setups.

i_square_cyanCustom notification scripts are also available in the PRTG Sensor Hub.

SMTP Delivery

i_round_blueThis documentation refers to an administrator that accesses the PRTG web interface on a master node. Other user accounts, interfaces, or failover nodes might not have all of the options in the way described here. In a cluster, note that failover nodes are read-only by default.

Setting

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.

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.

i_podThis option is not available in PRTG Hosted Monitor. PRTG Hosted Monitor uses SendGrid for email notifications. For more information, see the Paessler website: FAQ – PRTG Hosted Monitor.

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.

i_round_blueIf the name contains angle brackets (<>), PRTG replaces them with braces ({}) for security reasons. For more information, see the Knowledge Base: What security features does PRTG include?

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.

This setting is only visible if you select SMTP relay server above. Define the connection security for SMTP connections:

  • Use SSL/TLS if supported (default): Use a Secure Sockets Layer (SSL)/Transport Layer Security (TLS) secured connection.
  • Do not use connection security: Use an unsecure connection with plain text transfer.

i_podThis option is not available in PRTG Hosted Monitor.

SSL/TLS Method

This setting is only visible if you select SMTP relay server and connection security above. It is only relevant for secure connections. Select the SSL or TLS version that your SMTP device supports. We recommend that you use this option. If you do not get a connection, try with a different setting. Choose from:

  • SSLv2 or SSLv3 (default)
  • SSLv3
  • TLS 1.0
  • TLS 1.1
  • TLS 1.2

SMS Delivery

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.

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).

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

i_square_cyanFor information about sending SMS via separate hardware using third-party software, see the Knowledge Base: How can I send SMS text message notifications via a modem or a mobile phone with PRTG?

Define if PRTG sends the Server Name Identification (SNI) extension to the Transport Layer Security (TLS) protocol along with the HTTP request:

  • Do not send SNI (default): PRTG does not send the SNI when it executes the HTTP action.
  • Send SNI: PRTG sends the SNI when it calls the target URL. Specify the SNI below.
