<%NUMBERING1%>.<%NUMBERING2%>.<%NUMBERING3%> PRTG Manual: Notification Templates

Send test notification ()

Triggers the notification immediately for testing purposes.

When you test notifications, PRTG does not resolve the placeholders, but rather sends the original variables instead.

Used by ()

Show all objects that trigger the notification.

Pause ()

Pauses the notification.

If you manually pause a notification, PRTG does not send messages when this notification is triggered.

Resume ()

Resumes the notification.

Clone ()

Creates a clone of the notification.

Delete ()

Deletes the notification.

You cannot delete predefined notifications.

Settings ()

Opens the settings of a notification template.

Template Name

Enter a name to identify the notification template.

If 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?

Tags

Enter one or more tags. Confirm each tag with the Spacebar key, a comma, or the Enter key. You can use tags to group objects and use tag-filtered views later on. Tags are not case-sensitive. Tags are automatically inherited.

For performance reasons, it can take some minutes until you can filter for new tags that you added.

Status

Select the status of the notification template:

• Started (default): PRTG executes the notifications that are defined in the notification template whenever it is triggered.
• Paused: PRTG does not execute any notifications that are defined in the notification template.

Schedule

Define if you want to use a schedule to activate a notification template only during specific time spans. This way you can pause notifications, for example, during regular maintenance periods or system restarts.

• None
• Saturdays
• Sundays
• Weekdays
• Weekdays Eight-To-Eight (08:00 - 20:00)
• Weekdays Nights (17:00 - 09:00)
• Weekdays Nights (20:00 - 08:00)
• Weekdays Nine-To-Five (09:00 - 17:00)
• Weekends

The overall status of the notification template must be Started (default) to apply any schedule settings.

For more information, see section Schedules.

Notification Handling during Scheduled Pause

Define how PRTG handles notifications that are triggered during a scheduled pause.

• Collect notifications and send them when reactivated: PRTG collects all notifications that are triggered during a scheduled pause and sends them all out once the paused status ends.
• Discard notifications during paused status: PRTG discards all notifications that are triggered during a scheduled pause.

If you manually pause a notification, PRTG never collects notifications that are triggered while the notification is paused.

Method

Define if and how PRTG collects and summarizes several notifications into one or more messages with a maximum of 1,000 characters:

• Always notify immediately, never summarize: PRTG always sends out one notification for each notification trigger that it receives as soon as possible, for example, immediately.
• Send first down message immediately, then summarize: When PRTG receives several down triggers, it sends the first notification immediately, then it continues to summarize notification triggers into one message, regardless of the sensor status.
• Send first down and up message immediately, then summarize: When PRTG receives several down or up triggers, it sends each first notification immediately, then it continues to summarize notification triggers into one message, regardless of the sensor status.
• Send all down messages immediately, summarize the others: When PRTG receives several down triggers, it sends out one notification for each trigger that it receives, but it summarizes notifications for all non-down triggers into one message.
• Send all down and up messages immediately, summarize the others: When PRTG receives several down or up triggers, it sends out one notification for each trigger that it receives, but it summarizes the notifications for all non-down and non-up triggers into one message.
• Always summarize notifications, regardless of type: When PRTG receives several notification triggers, it summarizes the notifications, regardless of the kind of notification trigger that it receives.
  The maximum number of notifications (see below) still applies.

Regardless of the option that you choose, PRTG never summarizes notifications of the types Send Slack Message, Send Microsoft Teams Message, Execute HTTP Action, Execute Program, and Assign Ticket because it always sends them immediately. PRTG can summarize the messages of all other notification types.

'first down' and 'first up' messages refer to the notification trigger condition and the clear condition respectively. You can also define warning or unusual states as notification trigger conditions or even thresholds or other triggers notification summarizations. The condition clear triggers, if applicable, are defined in the respective notification trigger conditions as well. The notification triggers all qualify as 'first down' or 'first up' messages.

PRTG collects up to 25 single notifications for one summarization and sends out the message as soon as this number is reached (or when the gathering time passes). If PRTG receives more than 25 notifications within the defined time span, you receive more than one message with up to 25 entries each. For example, if PRTG collects 74 notifications, this results in 3 summarized messages with 25, 25, and 24 collected notifications.

Subject for Summarized Email or SNS Messages

Define a subject that PRTG includes when it sends summarized notifications. The default subject is [%sitename%] %summarycount Summarized Notifications.

PRTG only uses the subject for the notification methods Send Email and Send Amazon Simple Notification Service Message.

You can use placeholders. For more information, see section List of Placeholders for Notifications.

Time Span for Summarizing Messages (in Minutes)

Define a time span in minutes to define how long PRTG collects notifications for summarization. Enter an integer.

If you enter a long time span, for example, 60 minutes, PRTG collects notifications for one hour before it sends them out summarized unless other features (see above) require an earlier message dispatch.

User Group Access

Define the user groups that have access to the notification template. You see a table with user groups and group access rights. The table contains all user groups in your setup. For each user group, you can choose from the following group access rights:

• No access: Users in this user group cannot see or edit the notification template. The object does not show up in lists.
• Read access: Users in this user group can see the notification template and view its settings.
• Write access: Users in this user group can see the notification template and view and edit its settings. However, they cannot edit its access rights settings.
• Full access: Users in this user group can see the notification template, view and edit its settings, and edit its access rights settings.

You can create new user groups in the User Groups settings.

Sender

Define which sender email address and sender name appear in the FROM part of the email notifications:

• Default: Use the default sender email address and sender name from the notification delivery settings.
• Custom: Enter a custom sender email address and sender name.

Sender Email Address

This setting is only visible if you select Custom above.

Enter an email address to use as the sender of the email notifications.

If you enter a custom sender email address, it overrides the email address in the notification delivery settings.

The outgoing Simple Mail Transfer Protocol (SMTP) server in the notification delivery settings must allow the email address so that it can deliver email notifications.

Enter a sender name to use as the sender of the email notifications.

If you enter a custom sender name, it overrides the sender name in the notification delivery settings.

Send to User

Select a user account to send the email notifications to. PRTG sends the email notifications to every active email notification contact for this user account. Leave None to not use this option.

Read/write users can send notifications to any user that is a member of the same user group as the read/write user.

Send to User, Send to User Group, and Send to Email Address all work simultaneously. Because of this, you can define more than one user as a recipient of this notification. PRTG sends the email notifications to the active email notification contacts of the user that you select, to the active email notification contacts of all members of the user group that you select, and to all email addresses that you enter under Send to Email Address.

Send to User Group

Select a user group to send the email notifications to all members of this user group. PRTG sends the email notifications to every active email notification contact of every user in the user group. Leave None to not use this option.

If you select a user group and a specific member of this user group as recipients, the user only receives one single email. This also applies if you enter an individual email address under Send to Email Address that is already defined as an email notification contact of the selected user.

If you define individual email addresses under Send to Email Address, define a specific user account under Send to User, and define a user group here, PRTG sends the message to the individual email addresses, to the individual user, as well as to the members of the selected user group. In all cases, PRTG sends one message with all recipients in the To part of the email.

Read/write users can send email notifications to all user groups that they are members of.

Send to User, Send to User Group, and Send to Email Address all work simultaneously. Because of this, you can define more than one user as a recipient of this notification. PRTG sends the email notifications to the active email notification contacts of the user that you select, to the active email notification contacts of all members of the user group that you select, and to all email addresses that you enter under Send to Email Address.

Send to Email Address

Enter one or more email addresses to which PRTG sends the email notifications. If you enter more than one email address, separate them with commas. Leave this field empty to only send email notifications to the email notification contacts of the user or to the members of the user group you choose above.

We recommend that you use Send to User and/or Send to User Group instead because you can then manage the notification contacts of users.

Send to User, Send to User Group, and Send to Email Address all work simultaneously. Because of this, you can define more than one user as a recipient of this notification. PRTG sends the email notifications to the active email notification contacts of the user that you select, to the active email notification contacts of all members of the user group that you select, and to all email addresses that you enter under Send to Email Address.
